Re: Panasonic TC-P50ST50 5" vertical black bar
Along the bottom left side of the "A" board (which has all the video inputs on it like HDMI) there are two fat ribbons and one smaller one. I'd see that both fat ones are seated correctly on both ends. Only make changes to these with power to the set disconnected from the wall.

Tom66, thanks for the reply. Unfortunately the warranty on these is only 1 year, so I'm well out by now.
By ribbons, I assume you mean those that appear to wrap around to the front, on the left side of this picture?
Which connectors should I be looking at?Leave a comment:

Just out of warranty I guess? Newish set.
I'd check all connectors along the C board, and check ribbon cable is fully seated.Leave a comment:

Panasonic TC-P50ST50 5" vertical black bar
My TV likes to intermittently flash this vertical line
.
I read the troubleshooting guide from here, and my best guess is the "Vertical Line-Same width as FPC" even though the blacked out area is larger than what they say it should be.
I took off the back, wiggled around the cables and reclamped them which seemed to make the problem better. Prior, the black bar would show 20%-30% of the time, after my calibrated wiggle they disappeared for a couple weeks. Now, they are back at 70%.
Any suggestions on what to try next?

Thanks for offering your assistance with this. I'm an electronics enthusiast with moderate level of competence (have a decent lab with two power supplies, microscope, DSO, hot air, good iron, can competently work at a component level on SMDs, design and solder own PCBs etc). I really enjoying fixing things and learning new stuff so took up a free 58" LED TV and have been googling and watching Youtube videos to see if I can fix this! I am happy to go down to individual component replacement/strip replacement etc - it's all in the name of learning.
The issues are as follows: the... -
Hey guys,
I had a previous thread about this TV here: https://www.badcaps.net/forum/showthread.php?t=79192
My problem was the top half of the TV had went out and the problem ended up being on the SU board.
That problem is now fixed and I am left with a different problem. There is a roughly 2" vertical black bar on the left side of the display and a single pixel wide red and green stripe on the right side of the display.
I have tried reseating the ribbon cables to the panel without any results. I do not think the TV had this problem before... -
Hello all. Only my second post.
I have a panasonic CF-20C5142VM which was booting to bios with no issues. I needed to add an ssd that was not initially being recognized by the bios. Found a link that suggested that I disable uefi mode and clear keys then to reboot to allow bios to now see New ssd. After restarting, screen is entirely black with no image. Found another post that suggested unplugging bios battery because some remnants of the bios may still exist in other parts of board but did not fix issue-screen is still black.
Anyone run across something like this before?... -
Hi
Asking for a friend.
I'm used to black vertical line in otherwise good image - probable solution is a rubber to push and tighten the COFs bonding.
but here its the opposite !
TV has new T-con = same issue
A missing panel voltage would have global effect
So , what should one do ? how can I find where the fault is ?
Thanks !... -
Hello,
I've acquired a 65" Panasonic TC-P65ST50 for free from someone while purchasing another TV for repair from them. I've repaired ~10 LCD TVs over the years with decent success, and I enjoy doing it. However this is my first attempt at a plasma, and I'm treading carefully.
The TV when I got it would power up, however the left ~5 inches of the display was entirely black, basically like a letterbox image would appear. I disassembled, looked up some info, and determined that it was likely either dirty/loose connectors between the panel and the C buffer boards...
