Picked up a Sharp TV off Craigslist with non working HDMI's. Had to replace the multiplexer switch IC chip to get the HDMI working on the 4 ports. Also grabbed a 50" Pioneer Elite Kuro on Craigslist from someone in the Coquitlam area. Cant wait to get that up and running. Love watching and learning from you and Norcal. Keep up the great videos.
Yes the multiplex chip is what I figure was the problem on this one. A cracked solder connection on it. As all 3 ports were not working I suspect it was the chip, which selects the desired input. That is why I resoldered it as well, and there was cracked connections on it just like the ones I showed on the ports, but the ports needed to be done as well. I have a 50 Panasonic plasma. I forget the model off hand, but it was the real expensive unit that had the separate box with all the HDMI and inputs, outputs ect, and the screen was connected by a special cable. One of these days when it warms up a bit I will look at that one.
I enjoy watching repair videos on you tube, during which I have seen lots, by lots of different techs, but I think you are the best by far, you amaze me with the wide electronics knowledge of anything electronic. and in your commentary how you explain in depth the circuits, how do you recall it all? I am a very big fan Dave and I bet you have many. Liked, subscribed and donated, you deserve every penny you make...... Ray H. (From England UK)
Thanks. Even though I tried to leave this business, people track me down. Many old customers from my repair shop days look me up, as i am still in the same community, and work for a major telecom now so I run into old customers daily.
Well done :-D, What a bloody horrible connector. That microscope really helps :-) Hdmi didn't need to be such a tiny connector on tv's, a 25 D connector would have been better, bigger pads and stronger. Scart plugs/sockets were a pile of crap too, i thought they were a downgrade from so239 sockets. (yes i like coaxial better).
Beautiful video as always!! You are a master!! My hdmi port stop working because a bit of water flows in it. To repair, I need to remove it completely and put in a new one? Thx
I like that idea how you use the clock display on the 5 inch monochrome TV, and it would be different, I would love to add on the moon phase, sunrise & sunset info, and weather forecast for the screen. =)
Very nice video and professional. So like you said the HDMI cable sometimes gets heavy and pulling the port, but usually the port are not that fragile right? If you plug back and forth few times or by pushing it in and out ... It's not going to damage it easily right? Cuz one of my old TV , about 10 years old ... One day when I accidentally touch the HDMI cable or tilt it ... The screen dim and like on and off .. and when I tilt it again .. it went back normal ... Does it mean the port got losen? Since then every time when I plug the HDMI cable to any TV ..I am afraid that I damage it ... Sometimes I need to move the cable cord a bit and I started to worry that when I move I will losen the port from the motherboard .. but I think they are quit secure and not that fragile .. hope you can tell me ... Thanks again
Hdmi ports are fragile. The solder to the main board cracks. Using heavy monster cables makes the problem worse. Sharp tvs with the side mounted ports were really bad.
Deal with brioken charger port's and HDMI port's and sometimes multiplexer switch IC chip daily. I still don't get how people break them? I seen one even completly ripped out of a PS4 just yesterday, shockingly traces were still on the board. The worst to deal with as muiltlayer board is so thick and had to use alot of heat on both side of board which sucked. Best and asy way to help prevent bridging. Is to use 0.025 to 0.020 diameter solder and to use alot of no clean flux and just drag across the pins with the bevel tip at a angle. Or just use the paste and add across pin and use hot air. Uusally just do these manually as can be quicker for me at least. Never use a pointed tip.
Thanks for the video, i have a smiliar samsung board that has 4 hdmi ports, plugging in an amazon firestick on all the ports and the TV recognizes it in the input menu but goes into a no signal message on the screen. I replaced the HDMI chip but still have the same issue. From your experience could one port be causing the issue or something worse like a processor issue. Thanks!
I had a lightning strike 10 m away from my outside TV aerial. Since then one of the HDMI ports on the back of the TV isn’t working. It was connected to a DVR recorder which was connected directly to the outside aerial. Is it possible that this would only take out one HDMI port or do you think something else calls the HDMI port to file? Cheers Wayne
It's an old Blackberry. I ported in a clock app years ago, and it drives the HDMI output (Blackberry had an HDMI out on the Z10, Z30 and Playbook tablet) The HDMI out goes to one of those cheap HDMI to AV converters, which drives a modulator and it hits the house cable. Since the phone still has a sim card, deactivated, it pulls network time from the cell network, and it accurate to GPS accuracy as the cell towers are all GPS synchronized. I have a few different clock apps I can run on it. Eventually the tube will burn in I am sure, but that will take awhile. I have had it running on another old monitor for over a year and no lasting effect.
HDMI is always a trouble spot with some flat panel sets but straightforward enough to repair - same with A/V inputs. The bonus here is that you didn't have to replace any parts.
Interesting video! I have a Sharp TV where only one HDMI connector is used but all of them have stopped working. I assume that's a chip problem as opposed to a fractured connector?
Yes I suspect it was a broken connection on the chip on this one as well, but it was obvious that the ports were loose as well as they were visible. I did the chip as well, but didn't gets shots of it due to a bad camera angle. I did show it at the end before powering up. Set working great now.
a thumbs down means nothing, other than to hurt your feelings. none of your hard-core subs would ever do that to you. its a well made video, you put work into it!
Hey, I’ve been looking all over (evidently in all the wrong places!) for an answer to my problem. Samsung Plasma TV 550 series, works fine and the started to bugger up. The problem is the will display certain device ie Xbox 360, but not ps3. PS3 works on other TVs ... I’m at a lost. If the ps3 « works » and I use all the same configuration as of Xbox (same port same HDMI cable) why won’t the signal pass?? Please any ideas??
I have a samsung blu ray player, the signal appears 1 second later it disappears, some idea that could be, the connections are fine I do not see welds in bad condition
Hi ..I really need help . My smart tv is fine but using HDMI , it will lose contact or turning off and on everytime we use washing machine or other equipment even the lights . Please i need your advice. Thank you
16:06 There is a bridge ball on hdmi port legs, which you left accidentally. You're pointing that spot with your nail. Too bad that this is old video and it is too late. Or maybe those pins (legs) had common trace, so there was no point to separate them.
you're right. I'm trying very hard, for nice grateful customers, I fix things from them, like mine own ones, but for the bad pain in the ass customers, I do what I have to do, and nothing above it.

Professional troubleshooting and repair. Impressive to watch and learn. Thanks.
Good diagnosist and good work. Soldering the 3 hidmi and the ic it's a good work 👍
Exactly in my case! Thank you very much!!!! The HDMI now working perfectly!

Great video Dave and a neat repair. Thank you for making these videos and sharing your knowledge. Regards, Dave

luckily my old LCD Tv only has DVI nobody uses tv speakers anyway with blu ray. lol.

Dave, what are you using to drive the little CRT clock?
He has a video. Just watch all of them. I did a benge watch on his videos when I first found his channel.
It's an old Blackberry.

Can you follow that technique for any samsung tv, I have a UN58MU6070?

(@15:58) it looks like there’s still a solder bridge on the HDMI connector closest to the IC (shorting the 3rd and 4th pins from the right.)
But there isn't, because if there was the TV would not have worked, and it probably would have gone poof.
well done
If it was so well done why is there a thumbs down.
Because that one person who gave you a thumbs down is a jerk, that's why.
a thumbs down means nothing, other than to hurt your feelings. none of your hard-core subs would ever do that to you. its a well made video, you put work into it!
why the hell didnt they
screw the socket to the back panel for strain relief?
It even has the holes to do so with! >.> Samsung

How on earth do you manage to solder something so small, you must have a real steady hand.

Ray Hindle your gay
My hdmi prong it’s self is loose causing it to go out. Now not coming on at all.
what a poor HDMI socket design... two small tabs holding it to the PCB... it's made to be broken easily, i guess..
HDMI was a bad idea to begin with. Worse is micro HDMI. Firewire is also a fraile connector as is microUSB
The biggest flaw is how those HDMI poerts are mounted, since the weight of the cable would pull them down.
"Monster" cables don't help either.
@@12voltvidsyes but those videophools think they can see that 1 pixel per frame difference. So they get the biggest phattest cable they can find.
@@tacofortgens3471 good salwsman will sell them the biggest cable in the store.

Sounds like you need an electrician to figure out your power problems.

Considering this TV belongs to a pain in the ass customer there is no problem as if there was it would have been back long ago

The guy that owns this one is a pain in the ass. Bought 2 tvs from a hotel that was shut down and wonders why both had problems.
...and lead-free solder is weak and unreliable - frequently the source of trouble under ICs that get hot (GPUs, etc.)
Lead free solder is a bad joke. We can thank the EU for that one.
Sir my lgrh387h dvd hello problem
What model was this?
I didn't list the model as this is not model specific. The same board is used in multiple models. This was an LN32b460 for the record
