Mezmerising. I could sit and watch that skill at work all day. Amazing to see (to us mere mortals and however expensive it originally was ) now defect disgarded "junk" being brought back to life in this way. Had a great 17 minutes - thanks!
Very smooth troubleshooting and quick component replacement. For a lower end Harman Kardon I thought the build quality was totally adequate. Keep the videos coming. Thanks!
Awesome job man. I have the same issue with no sound output, with an AVR 235, but none of the fuses are blown. Even so, this video inspires me to try and search for the error and repair it.
NSluyter There's a surprising amount of commonality in some receivers - especially the amp sections. A Pioneer VSX-1021 for example has an almost identical amp unit to a Denon AVR-1910. I jokingly say that they "came out of the same hole". Anam is the big Chinese company that makes these.
Haha, must be a big hole! They probably make >50% of all receivers/amps. Price for a new AV receiver is so low nowdays, for $250eur you have a nice receiver. This must put some pressure on the repair market, such repairs quickly take you 1/2 day or more. Maybe you interested in my fb group facebook.com/groups/1624348004467344
Thank you :) Sorry to hear yours have failed too :/ I wouldn't trust those caps any further than I could throw them ! Worth a check indeed. Good luck with the repair!
Nice video! Question. I have a Harman Kardon AVR 354 receiver that behaves strangely. Random sound dropouts (lasting for ~1 second) occur in all sound modes, all inputs, with or without any external connections. Strangely, during the sound dropouts the front panel (and volume light/led) black out. During those intermittent and random sound/display dropouts, the power led remains on, and (apparently) all the relays stay on. Between these occurrences, the unit functions "completely" normal. After a while (time varies 10-20 minutes) the sound drops off completely (but the unit stays on, and the front panel working OK), but reappears "normal" once you switch to another input. At other (rare) times, the sound goes completely awry (~whistle). I tried repeated CPU resets, doesn’t change anything. In an attempt to see if anything wrong with the DSP/CPU, I reinstalled the most current firmware (this is done with the unit in standby), and everything went OK. The F110, F111 fuses and wire (jumper) from HDMI board to Regulator board upgrades (as per HK bulletin) have been addressed by the previous owner. I also measured different voltage (regulators), but all seem OK. Of course, the problem is that this issue is intermittent. My question is what connects the sound drop with front display and volume boards concomitant malfunction. I didn’t see anything similar on Internet; have you any idea where to look? I have basic electronic (incl. soldering) skills, if I only knew what needs to be checked/replaced.
I have inherited an AVR700 which seems to have a similar issue, lights but no sound. It's very similar inside so I'm hoping to use your excellent troubleshooting video to diagnose mine. One side note, I did find out that the "Tape Output" was producing audio when connected to a separate amp. The headphones output is dead. It seems like the issue lies after the preamp section. Thanks a lot for your excellent video sir ! Wish me luck, I'll report back.....
ive got an AVR7550hd. unit will work just fine for random amount of time (between 5secs and an hour) then shut down saying "4ch sensor failue" any ideas or thoughts?
Hey there great video! I have an HK AVR 132. It had been lying for a while & I set it up again today after a long time. I used to use a set of 8 Ohm speakers on it. This time I decided to add another set (which read 7ohms) and connected them in parallel to the stereo out put. I had not tested the amp before connecting the speakers. When I powered it up it played radio for a few seconds before displaying "PROTECT" and switching it back to stand by. I immediately disconnected the speakers and tried again this time it went to "protect straight away without even playing for a few seconds.. I read in the manual that you can reset the device by keeping it in standby and pressing the surround mode button for 5 secs. So I reset the device successfully and tried again but still the same situation. I realize that the resultant impedance from the 2 sets of speakers connected in parallel was around 3.2Ohms(both by calculation and on the multimeter) which is too low and almost a short circuit. Any ideas what I might have blown?
Naushad Kharas Hey! :) I am not sure but I would start by checking the fuses, then the output transistors (even though a few seconds shouldn't be enough to blow them :/ ) ! Is the AVR 132 rated for 8 ohm speakers ?
EcProjects Unfortunately unlike the AVR130 that you worked on there is no conventional fuse. The back panel has 8ohms written on it. I will check on the transistors. Thanks
great video. i have an avr5000 that loses memory (retune the radio and speaker settings) when the mains power is turned off. do you know where the memory cap or battery is located that maintains the memory?
Just wanna say great job.. Hopefully one day i'll have the knowledge you do. but for now i have a question (favor) I have a harman kardon avr 247. The problem i'm having is that when i turn the receiver first it works fine. But when it gets warm or hot and i turn it off. and i turn it back on, it wont work, no picture . i have to wait for a long time or the next day to work. Any suggestions??? Thank you..
I have Hk HKTS 7 hooked with HK AVR2550. Everything works as it should but no sound from any speakers. I have tried changing sources, changing place for optical cable, just opened the avr today and couldn't find any tell tell sign of anything, rather overwhelmed with those complex looking circuits. Any help guys ??
Nice repair video... I have harman kardon avr 156 model which is stuck on standby mode and doesn't come out.. Can u please suggest me what might b the problem nd where might I look for the problem.. Tried resetting doesn't work..
Thanks :) That would be hard to tell. But yea, it could easily be an electrolytic. If you have a multimeter, you can try measuring the resistance across the caps to see if they are shorted. But even if the resistance across the cap is 0 it can still be another component on the same rail. Hope you'll find it :)
Hi, nice video, thanks for sharing. I have an HK AVR 7300 which start only for a second, then goes off. I've tried reset, it shows reset on the display, but then it goes off again. I've checked all the fuses and all are ok. Can you give me an advice, please ?!
Hello, did you measure the outputs while the device was turned off and unplugged ? The resistance on the outputs can't tell much normally, because there is capacitors and transistors in the way of the measurement. But if you leave it powered off and unplugged for a little while and measure the terminals, and then as you say only one measures significantly lower, it could indicate a fault in that channel.
Hey, to me it sounds like something went wrong in the digital / processing circuitry.. But can't get any closer i'm afraid :( Does it show the Incoming signal data on the display when you connect a coax/opt cable while the receiver is on ? (I.E. PCM 44.1 Khz for 5 sec, or whatever you are using :P )
Yes I had myself quite a surprise as well, I did not expect to find low reliability components in such a unit. There was not a 105c or brand name cap in sight. It does sound pretty good actually. But obviously they don't care about if it's gonna last or not.. -Mads
Hey.. It could sound like a shorted capacitor, they can sometimes come good again after a while, and then fail again when they heat up.. But that's just a guess.. I think your approach is the way to go :) If you can find the schematic you can see if any devices could have failed between the two points you measure :)
I have a HK AVR 247 that someone spilled a coke on... everything works except... no sound. Pretty important feature. Any advice on trying to clean things up on the inside? There could certainly be some other issues... most important one first. (sigh)
+liamlad1 You had me laugh at "Pretty important feature" ;) I would recommend using Isopropyl alcohol and a brush (antistatic if possible), for the electronics at least. Just make sure it has stayed unplugged for a while when you do it..! So there is no charge left in the capacitors. Also check the fuses :)
Hello, My HK AVR255 makes a thumping sound across all speakers and headphone also. The thumping gets faster and slower all on his own. Can you please help me and tell me where to look? What board i should look at, what to measure. Im a newbe at this and would love all the help i can get! Thank you for the video.
Hello. I have an avr1710 that didnt want to power on, however it would ‘reset’ using the front surround mode key. I found and repaired the key2 track below the screen overlay and now all button show activity in their respective pins key1 and key2 bit still not powering on. Now it wont even reset with the surround button. Could you please help me troubleshoot this receiver? I know its a big thing to ask, but I dont know where else to look. Thank you.
hi I have AVR254 and its not response to the remote control and there no response to the front panel just the LCD in DVD mode and I can't change the mode there no any operation I replace the the big caps with the same type and there is no operation still and I did a reset by pressing the OK and still can you help me ...thanks
can any one help my avr 130 having muting problem the audio signal reaches at main amp but so sound out put but when i chek the amp section only it also work fine
Hi - great vid , my AVR 507 LE seems to stay in standby, orange light only - could it be a case of replacing these big capacitors also, or should I be looking somewhere else ?
Great video- very comprehensive and impressive to the detail! I have 2 HK receivers- AVR 635 which basically freezes after an hour or 2 of power on and becomes unresponsive to remote or the front panel controls. The other receiver is a AVR 347 which has the same symptoms. Problem is sporadic and frustrating, can you direct me where to begin and probably give me a hint of which items need attention. Thanks a lot.
+Jay Em Thank you! Hmm, does it stop playing also ? It could be something with the processor, perhaps the power supply for it dropping out or something.
fernando chicopop22 I found mine on Google by searching for service manual or schematic :) Ohh, yours was there as well: elektrotanya.com/harman_kardon_avr_139-141-142_230_service_manual.pdf/download.html You just need to wait a while for the "processing" to change to "get manual" on the site :)
Thanks for the tip :D I did actually think of doing that, until I saw the damn prices :O Hehe The 6,8 mF caps are $20 (us) EACH! Here in Denmark :P The 4,7 are "only" $5,5, so I refused to pay the extra 30 ;) We wanted the receiver up and running before Easter, else I would have ordered from the US where its half the price including shipping + import duties O.o -Mads

Hello EcProjects, thank you for this informative youtube video. I have also an issue with the AVR 130 but in my case the right sound doesn't work if I plug the right speaker into the left input it works fine and when I plug the headphones into the AVR just left side works fine and no sound on the right side. Maybe, you know a solution to this. I would really appreciate to hear from you. Best regards!
Excellent video, I have a subwoofer infinity SW12, which was shut down running, seeing the board I see that the fuse is blown. this has nothing intact all physical short and is no longer under warranty. What can it be? Perhaps capasitores will be the electrolytic?
It powered back on and. I measured the resistance of the speaker outs and the SL is significantly lower than the others. Could this indocate a fault in this section of the amp?

Hi I have a Harman /Kardon AVR 120 the problem i'm having is i turn the volume up and down and suddenly it stopped working, how can i fix it. Any suggestions? Thank you..
Can I get the part numbers for the (4) high temp capacitors. I have a HK AVR 240 that powers on but no sound output that had them replaced a few years back now it happened again.
Shawn Hoetger I don't know if the AVR 240 uses the same capacitors, but here is what I used for the AVR 130 (different brand of caps):50VXG4700MEFCSN30X30 and LGY1H682MELB35 I tried to link to them, but RUclips screwed up :) You can find them on Digikey.But to make sure, you can measure the dimensions and pin spacing of yours, then put those along with the ratings into the search table of digikey or any site you prefer :)
My receiver works (i.e., I get sound with all of the devices hooked up to it) but I can't see the display screen. It appears as if the screen light went out. Any suggestions/tips on how to fix it?
***** Hmmmmm. There is a lot of possibilities :/If it is the backlight, you could hope there is a fault in the power rail. You can try to search for a schematic online, and measure the voltages. (Careful: There are high DC voltages on the amplifier board ! So don't touch it !)
HI, thanx for the video. I have an AVR 255, and after 2 years there is no Audio at all, but only Video. It all started maybe 3 months ago by not having audio sometimes when you first turn on the AVR, but after restart the audio usually was back. By the time it started to happen more often, till one day it was gone forever. All audio outputs are dead incl. h-phones, no radio. I tried to reflash the firmware, but during the flashing the audio part, it stuck. Do you think it's repairable? Thank you
Hi thanks for reply - I already sent a reply but I can't see it anywhere... so I will write it here. I measured both on and off but the SR channel showed a much lower resistance between +ve and GND than all the other channels. After about 2 hours of gentle use, it tripped again and powered off. I re-measured and there was Zero resistance between the +ve terminal - therefore a short I guess. Best thing now is to just trace back from the output and perhaps compare to the SL channel ? thanks
hallo! Ich brauche Schema Harman Kardon Subwoofer SUB 230 (drahtlos), so dass ich versuchte, es in einem klassischen drahtgebundenen arbeiten, können Sie helfen ?? oder Beratung
The 10 mF is the same about price as the 6,8 mF here unfortunately, but they didn't have any in stock that would fit. It had to be less than 32 mm Ø. And they only had 35+ mm available. :( -Mads
greetings from the UAE-ABU DHABI, i have an old HK AVR 130, it turns ON and OFF (sometimes) and while its ON, i connected 3 speakers for a while (center, right, left), somehow its only LEFT. tried MASTER RESET, set up speaker volume, balance, did not work. need help. i want to salvage this old AVR of mine. (its old i know). NEED HELP
I would have made them all 6800/50 caps, a little more value is always good on a power rail. Only issue would be going massive overkill which might pop fuses at power on.
Holy shit! thats an expensive multimeter from Fluke :O. My eyes boled out when i saw you measuring that resictance with 5 decimals :O drewling out here :p
Hi, I'm afraid it could be one of many different things.. But I would recommend starting by checking the voltage rails. And check if any fuses or components are blown :)
Heh, I was lucky the Fluke meter showed up just days before the receiver blew up. My next best does only 2 decimals, which wouldn't be easy to find a short with.
You probably could have gotten 10000uF units for the price of the 4700 ones though. 47 and 10 are the most common values and the multiples in capacitors nowadays, the other values are less common.
Hello, great video. I have an AVR7000 that has worked without issue for 16 years. Now the pre-amp board has an issue. I'm in Canada, do you have any idea where I can purchase a pre-amp board for this unit? part number J4025100100A. Thx.
i have the same receiver. i was watching tv and all of a sudden i had no more sound, when i run the speaker test i can see it working in the display but there is no sound, anyone any idea what might cause this?
Heer Ollie I would start by checking the fuses. If blown, then measure the resistance of that power rail (when powered off of course). If it is close to 0 Ohms, there is a good chance it is one of those caps :) But it could easily be something else :)
EcProjects the repair man told me two transistors and a chip were broken, the costs would be 90 euros. with these kind of things you never know if he is bullshiting you or not. then i ask myself how likely is it that 3 parts break down all at the same time? or am i overreacting?
If he already did the repair, it's probably true :) The price is mostly labor anyway with those components :) If he didn't, it would be very hard to tell exactly what have failed.
It would be good if you played some music to demonstrate the fix. Amplifying static from an AM station detracts from an otherwise nice video. Go the extra mile and play some nice music.

Really liked this diagnostic video. Please do more.
Many Thanks for sharing,
Thanks, I'm glad you liked it :) I will definitely do more..
Great video. Would like to see some more. Thank you.
Great repair!
It was the capacitor this time, but sometimes an insulator fails at an output transistor. Seen it a few times - causes the same symptom. Good Job!
Thank you for mentioning that :)
Have you seen the Marantz SR4000 series inside, its almost the same. Wonder what relation is between HK and Marantz!

JVC 5.1 Surround Receiver.100Wx3 per CH. front L+R+C 20W x2 SUR. rear L+R speaker wire crossed shorted out now NO POWER LIKE A FUSE BLEW! HOW DO I REPLACE IT ?
I HAVE AVR 130 HAS SAIM PROBLEM HOPE YPUR VIDEO WILL HELPFULL THANKS
Hello EcProjects, thank you for this informative youtube video. I have also an issue with the AVR 130 but in my case the right sound doesn't work if I plug the right speaker into the left input it works fine and when I plug the headphones into the AVR just left side works fine and no sound on the right side. Maybe, you know a solution to this. I would really appreciate to hear from you.
Best regards!
How to fix No Front Display? Thank you.
Fantastic video, very nice work! Did the failed caps show any evidence of failure? Like swelling, leaked electrolyte, etc?
Protonus There were no signs, but I did take one apart and found a short inside. I've got a video about it :) Thank you !
Excellent video, I have a subwoofer infinity SW12, which was shut down running, seeing the board I see that the fuse is blown. this has nothing intact all physical short and is no longer under warranty. What can it be? Perhaps capasitores will be the electrolytic?
It powered back on and. I measured the resistance of the speaker outs and the SL is significantly lower than the others. Could this indocate a fault in this section of the amp?

amigo por favor podrias subir el esquema del amplificador avr 130 porque tengo una salida de audio quemada y le he cambiado los condensadores pero sigue igual
Nice, how you threw the cap away. I like, how u do your repairs ;)
+fellpower Thanks :)
Hello,my avr 130 goes sleep mode after 10…15 minutes.
Any idea?
Please help me with schematics.

Hi I have a Harman /Kardon AVR 120 the problem i'm having is i turn the volume up and down and suddenly it stopped working, how can i fix it. Any suggestions? Thank you..
Yeah, I thought of that too :D... I still have it though, so I can still do a video :)
Hello I’m having a issue with mine everything works but when I try to hook up the front right speaker nothing comes out of it…
hola por favor donde puedo comprar estos discapacitadores me puedes dar un link de la paguina we para comprarlos gracias
Can I get the part numbers for the (4) high temp capacitors. I have a HK AVR 240 that powers on but no sound output that had them replaced a few years back now it happened again.
Shawn Hoetger I don't know if the AVR 240 uses the same capacitors, but here is what I
used for the AVR 130 (different brand of caps):50VXG4700MEFCSN30X30 and
LGY1H682MELB35 I tried to link to them, but RUclips screwed up :) You
can find them on Digikey.But to make sure, you can measure the
dimensions and pin spacing of yours,
then put those along with the ratings into the search table of digikey
or any site you prefer :)
I have one, i tryid connect speakers it doesn't work, or i tried connecting to my plasma tv it doesn't work, i don't know what's wrong with it.
My receiver works (i.e., I get sound with all of the devices hooked up to it) but I can't see the display screen. It appears as if the screen light went out. Any suggestions/tips on how to fix it?
***** Hmmmmm. There is a lot of possibilities :/If it is the backlight, you could hope there is a fault in the power rail. You can try to search for a schematic online, and measure the voltages. (Careful: There are high DC voltages on the amplifier board ! So don't touch it !)
You will wear gloves and set the fuse. Otherwise it will become rusty after a few days. Thanks for this video.
HI, thanx for the video. I have an AVR 255, and after 2 years there is no Audio at all, but only Video. It all started maybe 3 months ago by not having audio sometimes when you first turn on the AVR, but after restart the audio usually was back. By the time it started to happen more often, till one day it was gone forever. All audio outputs are dead incl. h-phones, no radio. I tried to reflash the firmware, but during the flashing the audio part, it stuck. Do you think it's repairable? Thank you
nice
Sir my AVR surround speakers working main tower speakers not working what to do please advise
Hi thanks for reply - I already sent a reply but I can't see it anywhere... so I will write it here.
I measured both on and off but the SR channel showed a much lower resistance between +ve and GND than all the other channels. After about 2 hours of gentle use, it tripped again and powered off. I re-measured and there was Zero resistance between the +ve terminal - therefore a short I guess. Best thing now is to just trace back from the output and perhaps compare to the SL channel ? thanks
hallo! Ich brauche Schema Harman Kardon Subwoofer SUB 230 (drahtlos), so dass ich versuchte, es in einem klassischen drahtgebundenen arbeiten, können Sie helfen ?? oder Beratung
A set of short leads and the extra pair in the case somewhere works for me in those instances. Out of sight and easier to change next time.
The 10 mF is the same about price as the 6,8 mF here unfortunately, but they didn't have any in stock that would fit.
It had to be less than 32 mm Ø. And they only had 35+ mm available. :(

Good video sir same model Harman/kardon no audio no sound. voltages is ok wats problem sir
greetings from the UAE-ABU DHABI, i have an old HK AVR 130, it turns ON and OFF (sometimes) and while its ON, i connected 3 speakers for a while (center, right, left), somehow its only LEFT. tried MASTER RESET, set up speaker volume, balance, did not work. need help. i want to salvage this old AVR of mine. (its old i know). NEED HELP
hallo! potrebna mi je shema Harman Kardon Subwoofer SUB 230 ( wireless) kako bih ga pokusao preraditi u klasični žičani,Može li pomoć??ili savijet
I would have made them all 6800/50 caps, a little more value is always good on a power rail. Only issue would be going massive overkill which might pop fuses at power on.
Holy shit! thats an expensive multimeter from Fluke :O. My eyes boled out when i saw you measuring that resictance with 5 decimals :O drewling out here :p
hi whats the problem if i cant gett any sound from it bute everythink ells works ?
//sry for my eng
Hi, I'm afraid it could be one of many different things.. But I would recommend starting by checking the voltage rails. And check if any fuses or components are blown :)
I cannot see any fuses in my AVR-137...
Where can we download schematic ? Rezistor R782 Is Blown ..can read value to change
R782
part no : CRD20TJ750T
part type : RESISTOR , CARBON
part value : 75 OHM 1/5W J
That could also be the solution. Didn't really think of it though :P
Heh, I was lucky the Fluke meter showed up just days before the receiver blew up. My next best does only 2 decimals, which wouldn't be easy to find a short with.
Hi,how can i reset
hvor er du fra ? :)
i have an avr445 but dosn"t work, i dont have enough knowledge but I know where is the train
the last HK I worked on had one BIG problem....capacitors.... they were all junk!
Receiver..era espectacular en sonido..se apago...y esta como nuevo...lo vendo..en estado.ke se encuentra
You probably could have gotten 10000uF units for the price of the 4700 ones though. 47 and 10 are the most common values and the multiples in capacitors nowadays, the other values are less common.
Hello, great video. I have an AVR7000 that has worked without issue for 16 years. Now the pre-amp board has an issue. I'm in Canada, do you have any idea where I can purchase a pre-amp board for this unit? part number J4025100100A. Thx.
About the same*
You should have autopsied the dead capacitor to show the point of failure.
i have the same receiver. i was watching tv and all of a sudden i had no more sound, when i run the speaker test i can see it working in the display but there is no sound, anyone any idea what might cause this?
Heer Ollie Could be the same problem, but not sure :) Did you try the headphones ?
EcProjects hi. yes i did and also no sound. display is working fine but no sounds whatsoever.
Heer Ollie I would start by checking the fuses. If blown, then measure the resistance of that power rail (when powered off of course). If it is close to 0 Ohms, there is a good chance it is one of those caps :) But it could easily be something else :)
EcProjects the repair man told me two transistors and a chip were broken, the costs would be 90 euros. with these kind of things you never know if he is bullshiting you or not. then i ask myself how likely is it that 3 parts break down all at the same time? or am i overreacting?
If he already did the repair, it's probably true :) The price is mostly labor anyway with those components :) If he didn't, it would be very hard to tell exactly what have failed.
It would be good if you played some music to demonstrate the fix. Amplifying static from an AM station detracts from an otherwise nice video. Go the extra mile and play some nice music.
