Re: panasonic TC-P50S30 50 inch
Test for a short on the SC across where the brown and white wires would go, with the connector unplugged from the SC.
Note buffers may get power thru those screws, seen it a few times!Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: panasonic TC-P50S30 50 inch
Surprising for Panasonic to say that, but I have heard of the plasma panel going short circuit between lines. Unplug buffers to confirm.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

You can run it with one SU or SD, then jump SC50, for half a picture.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: panasonic TC-P50S30 50 inch
First post!
Got the same TV and found the SC board was shorted. I replaced and TV powers up but picture is funky. I'm sure I'm not the first, so should be easy for you guys to point me to what now needs replacing. I have attached a picture. Basically pinkish blue on both sides with a dark ghost image in the middle. Thanks in advance.Attached FilesComment

Yeah, I started my own thread and worked through the issue, including a lot of stupids mistakes on my own part. You can read it here: https://www.badcaps.net/forum/showthread.php?t=38527Comment

My old plasma died when one night recently. When I got to it it was giving a 3.3v sos (3 blinks).
I chased my way through the PSU, and a board, with no results.
Replacing a few bulged caps in the PSU, I eventually got to the SC board that had piles of shorts, a quick cheap replacement from china and the tv powers up again, except
I only have the right half of the picture.
Left half is completely blank.
now the c3 board running this side of the screen has its 3.3 and 5v onto the buffer ic and its got the 60v, so that all seems good.

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.

Good day,
I have tried to remove BIOS supervisor password from Panasonic Toughbook CF-33 mk1. Model number CF-33AENABTG, unfortunately I don't have any other info.
I read the BIOS using afuwin, edited it and tried to flash new edited BIOS using afuwin. Unsuccessfully. Afuwin showed "Error: Problem erasing flash." starting with 0x00040000 and stoped. Then I tried many other options to flash BIOS from Windows without any luck. Finally i rebooted the device - and no post. Afterwards I have read the corrupted bios chip (MX25L12873F) using EZP2010 programmer....
