TV is completely dead.There is 320 volts across main smoother cap but no voltages on the secondary of the power supply.I have seen a couple of people offering a repair service for the board on fleabay for this fault.Does anyone know what the repair is? Searching on the net it seems to be a common problem after switching off from the mains.

Re: Panasonic TX-P50X50B
The mains input fuse is OK.Is there another one? Some people are saying that if the set is left unplugged for a while it sometimes will work again.Last edited by blib; 01-26-2014, 10:01 AM.Comment

Picture of PSU?
I have a dead 42" X50B PSU here, too. No standby light. Got it from a cracked panel so no idea if external damage did it in, or the guy smashed the screen in frustration.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Greetings All
I have Panasonic CF-D1NW200TZ,
SN: 8GTSA90529
The BIOS (MX25L12873F) is password-protected. I want to remove the password. I created a backup using NeoProgrammer and removed the password. Then, I restored the unlocked BIOS file using CH341A, removed the protection, performed a full wipe, completed the process with a blank check, and then wrote and verified it. Everything seemed fine, but now the tablet won't start. Only the power and Wi-Fi LEDs are lit, nothing else. The fan isn't spinning, and nothing else happens.

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.

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 😂.

Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in... -
Hi everyone!
I happened several times, in the search for help from the web, to consult this very interesting forum.
So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.
Having said that I come to the gist of my post on the forum as the title suggests.
For my passion for technology I'm now collecting several...
