Hello,
For some time now, there have been vertical lines displayed on the screen when there are light objects (like subtitles). It wasn't very annoying except that recently, upon turning on the TV, I get large colored bands that make it impossible to read the image. After a few power cycles, it comes back, it's random. I'm afraid that one day, it might not come back at all...
The images are attached... It's a Samsung LCD TV LE40856 that is a little over 5 years old...
I read in the forums that this could be due to contact or capacitor issues. I took apart the back panel, touched around a bit but saw nothing unusual.
On the T-com board, nothing specific either. There are traces on the two large chips (a bit greasy), I don't know what that could be.
I'm ready to try replacing the T-Com board (depending on the price) if someone tells me that it could be coming from that.
Thank you for your help or investigation advice...

Hello, I solved my issue with the vertical lines. By going into the cache menu, mute info menu power, I decreased the brightness parameter and the lines disappeared.
However, there are still issues at startup, with large colored bands, and I have to turn it off and on several times for it to come back. Does that mean the panel is okay and the problem is elsewhere (TCON board)?
Any opinions?
Thank you
