Hello everybody,
First post here. I have been reading posts here for some time now, but today I made my first account and post.
The same question is also posted on another site, here it is:
Just found an old Panasonic National NV-M3 VHS Camera without the original charger but with a special bag with a led, switch and fuse that is designed for a lead-acid 12v 6Ah battery. It has two cables coming off the bag that leads to the camera terminals (Only + and - ). Pretty sturdy design I think.
I tried connecting it to a Computer PSU (12.7v) but I get battery error...08-25-2025, 10:12 AM -
I picked up a Panasonic NH-P70G2, though it would apply to the NH-P80G2, NH-P70G1 and NH-P80G1 models as well, as maybe some other models. This one was coming up with a H86 error. After lots of testing and googling it was an error with one of the thermistors in the condenser area.
The attached French service manuals is incorrect, TH11 is gray and is a 95k thermistor and TH12 is black and is a 35k thermistor.
In my case TH12 was bad. I was able to get a 35k thermistor on AliExpress. It's 6mm in diameter.
Unfortunately the whole machine has to come apart to fix it.

Set was manufactured in 2012. I'm trying to diagnose where the problem is. I am assuming it is over-currenting after heating up? Display looks fine until it decides to shutdown. If I keep turning it on, it will eventually refuse to power up and requires unplugging to get it to respond again.
I originally thought there would be some easily detected bad electrolytic capacitors, but I don't see the telltale signs. There might be some very minimal bulging on one of the x buffer board. BN96-22092A (LJ92-01852A).
If I unplug the power feed to the X/Y board (LJ92-01854B), the... -
Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
TV Model: Panasonic TC-P55ST50

Good day folks. I wasn't too sure whether I should start this discussion just yet, because I feel I haven't dug deep enough, which I can't do until Monday at work, but I eventually thought I'd just go for it so by the time people start joining in, I'll hopefully be able to complete my measurements.
TL;DR - Panasonic KX-NS500 PBX sometimes dies - PSU issue (schematic attached). 41v rail drops to 25v and 15v rail goes off entirely. Often, even a power cycle doesn't restore it - main cap (C4) needs to be "manually" discharged for it go gain.
