There's nothing better than watching one of your splendid VCR repair videos during these soul destroying lockdown's - much better than all the mind numbing garbage on the telly - please don't stop !!
I have a PV--V4522S model. It is the exactly the same as this one, except mine has a silver color. I bought it from a factory liquidation place years ago, and it has relatively little use. I used it for my Mother and Aunt previously. It now sits in storage. It has been a good little machine. Another great repair!
VCRs are a very cool piece of tech! I wish sometimes they still made new ones for those of us who don’t know repair and have a hard time finding a good used one!
@12voltvids Norcal715 has been doing A LOT of VCR services as well. He always cleans the multi-mode switch with a small stainless brush and acetone. Those seem to be problematic with these units setting for so long as pots are on audio equipment. He uses acetone on so many things for 40+ years now. He lightly brushes the spring contacts in a manner that doesn't cause damage. He puts some new grease in before snapping it in. Then he uses glass cleaner on a swab to clean the optical sensors through the pass-through holes in the chassis and acetone on a swab to clean the heads & rubber parts. Just thought I'd mention. Love the videos on this channel. Different but useful techniques. Like the solder trick for test point. Hadn't seen that before.
99% IPA works as well on optical. Acetone is also an option but my old standby nutrol, not the new stuff but the old stuff from 30 years ago is really good. It has freon tf solvent as the carrier which was the best cleaner we ever had. I have 2 cans of old nutrol left. Deoxit is also good, probably the best we have now but the old formula nutrol was better. It was devoloped for the phone industry to clean Stroger and crossbar switches in the phone exchanges. IT cleans and lubricates so no need to grease afterwords as you would when using acetone. I am seeing VCR repairs now more than in the past few years.
I have a Panasonic Pv-7450 vcr and it has the same problem it is dead, it does not move the spool forward. There is a power transistor next to the large filter that hardly turns on the equipment, it gets very hot, burns the finger, thanks to this video I think I can fix it. I'm going to subscribe to your channel, it has helped me a lot. Thanks again
I remember this same unit being sold at Costco for $69.00 maybe 10 years ago. I don't understand how it can be made for next to nothing. Yes I still have mine and it still works!
Mass production my friend. This stuff was all assembled by robots with very little human intervention (at least close to the end of the format). Hundreds if not thousands of these units rolled off the factory every day.
I just had a recent dumpster find, it was a different make and model of VCR built around June, 1999. It needed some cleaning and a new belt, now it's operating properly
I'm still looking for a replacement video board for my Sony slv-r1000 it records and can use the inputs in color but playback is only B/w and i believe a critter relieved themselves on the board on the vents. i have since moved from that place but the vcr is still in need of repair
Thanks very interesting I like the diagnostics "Sherlock Holmes detection method" I did have a go at fixing a VCR back in 1994 bought the bits and yep it was a lot more complicated inside. Another VCR I bought In 1992 a fancy Panasonic that had SVHS and some sort of auto tracking or jitter control that I thought would help fix a wedding tape that had problems. A very expensive machine that I got at discount from a colleague that worked at the local factory. I sill have the plastic book with the barcodes and bar code reader pen for setting recordings; I think it was this Panasonic NV-FS200EG.
@@crashbandicoot4everr Sorry about that. I think mine had a worn out pinch roller, it has now been in the attic for over 20y next year I will get it out and have a look at it. I guess you can see why I wanted it to repair a badly recorded wedding video, I did improve it a bit but not much, a very expensive experiment. all the best.
I bought one of those new in June of 1994 (900 quid!!) and I still own it, (and the accessories and original box too!) although hasn't been used for 20 years. I moved to the US in 03 and that unit has been stored at my parents house every since. It worked then and I'm going to see if it still works next time I visit. It was great for playing jittery tapes and you could play tapes in reverse by setting the jog/shuttle dial, and with the sound playing. First thing I did when I realised it could do this was to test it with the Red Dwarf episode called Backwards and play it in reverse.😄Fun times. I also still have the Panasonic F75 from around the same time, similar in looks but slimmer and not as many features. But they looked great together in the rack under my TV.
Love the vid and teardown as always. Have a vcr that doesnt have power, probably due to the multi socket plug tripping about 30 times would could have shorted something inside. Do you think it can be saved since I dont have volt checker and the thing that looks like a electrocardiogram that you're using. Sadz.....
@@eDoc2020 Many thanks for the quick tip on the equipment used. Do you have any tips, sources or vids that will help explain these kind of circuit boards simply as I do not have any previous knowledge of electronics at all.
@@jafng6940 It's hard to say. If you're trying to fix a dead power supply, first thing is probably to check the fuses. If a fuse blew, you'll definitely want to build a dim bulb tester. If the fuse blew and it's a switching supply, check for shorts on the rectifier diodes and main transistor. Also check for cold/cracked/other bad solder connections. That's probably the main cause of totally dead units. Bad capacitors will cause issues but probably won't cause total death unless they're noticeably bulged or leaky. Ofc also look for other visual indications such as burnt or otherwise physically damaged components, and remember that power supplies can shock you. Filter caps will charge to around 170 volts when plugged into 120vac and may still keep a charge even after the unit is unplugged.
I bought 2 used Panasonic vcrs (not this exact model) and both had the exact same problem. First time worked, second time the tape wouldn't go in and the power wouldn't stay on for more than 2 seconds. I don't understand why.
I have that identical VCR... I went to go use it today, and found it no longer works. If you hit play or fast forward, it thinks for a bit, and then the power shuts off (and it goes back to standby mode). It will happily receive and eject tapes though.
I have some old home movies I want to convert digitally and I have a NEC VHS recorder but it starts to play and then it quits do you have any ideas or do you have a playlist thank you
Another great repair. A question. I have noticed that on the VCRs that you have worked on, non have a scart socket. All my VCRs have, as well as the RCA or phono sockets. Are scart sockets not used world wide? I am in the UK.
I used Scart leads and the sockets on various TV's and VCR's for years, as I have seen picture and heard sound interference through the Scart Connections, I no longer use them, I find that RCA/Phono gives better results. also Component Connection's give even better results almost as good as HD, I use RF whenever the RCA or HDMI connections are in use already.
have a JVC vcr only audio is heard, it has no video. I got an antimagnetic tape and after many tries, sometimes the vcr has video for seconds with dark teeth from above, I cleaned the head with a blank sheet of paper with isopropyl alcohol and managed to clean it quite a lot after several tries, but it still does not video. Can you help me, please. Reinaldo.
Yes I know it's 3 years late. Took mine to bit to clean. I broke the 2 sensors you cleaned. Tried to replace with 3mm leds but not working. Can find a spec for the leds or photo leds. Do you have any pointers for me. Was working before " I fixed it". 😢
I have a Panasonic NV- HD620 VCR which shows a rolling noisy video but with normal sound.. It shows a clearer picture when playing in fast forward. While cleaning I used soft moist cloth on head but without pressure. It was performing same way before cleaning also. Can you kindly advise what could be wrong in it? Is the head damaged due to cleaning by cloth? Suresh, India.
it is shutting down because too much light getting to the tape end sensors. if you can cover the unit with some cardboard to block the light it should play careful where you are putting your hands the board on the newer vcrs like that are live and can pose a shock hazard some vcrs may even use hall based sensors a hall looks like a small signal transistor and the reels have a small magnet on them and it works magnetically some vcrs use the control track on the tape to run the real time tape counter so that is why that when you put a tape in it will load it and run it for a couple seconds so it can get the position.
Hello friend. I disassembled a VHS Player and inside there is a Capstan Motor that has a Panasonic AN3844SB Controller Drive, but I can't find the Datasheet. Do you happen to know about this Drive? Thanks
I dont think the machine could be much simpler than that. Mains psu on the main pcb, yuck :-( The final ones in the uk were £30 to buy, next to nothing.
Everything proven people don't do good enough sodering tvs now days everything proven VCR players are tilling on tvs now everything proven when my new tv got my tv resoder my tv is doing so much better and picture is not moving like it did
Damm you are treading customers equipment without respect. They get som scratches - try to be more gently with the product you repair and get something on the table for protection. I'll will get fired if I treated customs stuff like this in my workshop. It only will cost the owner a lot replacement og free repairs.
This thing is already beat up, i doubt he will care. Incase you didn't notice i had to hit it to get the top on as it is bent. I can't get fired i work for myself.
@@12voltvids it's not only this video but most of yours video I see how your treat customers items. If they are scratch or not they must not get more scratches. Your job is to protect the item and return it in same shape as it came in the workshop... So. I don't know how its is in Canada but here in Denmark we show respect for others items

My Philips N6325 is something special. Can you bring it back to the '70 sound original? The sound now is at 80% i think. Can you get it to 110?
As you said "That is how all VCRs should have been made".

Good..we're your workshop..
Totally by accident I won’t be back
Geez, this is a major teardown. You have to wonder, was it worth it? Many of these cheapos have poor picture quality.
Ever since they outsourced the manufacturing to China, the reliability of stuff and the durability of stuff went down.
Really? I remember fixing thousands of them all labeled made in japan.
I dont think the machine could be much simpler than that.
Mains psu on the main pcb, yuck :-(
The final ones in the uk were £30 to buy, next to nothing.

If you say so, but boy does it look flimsy.
It does but these ones were actually quite reliable mechanically due to reduced parts count. Less to go wrong.
