Vertical lines - not TCON board - any ideas?
Hi,
I have a Samsung UE46ES7000 TV. For a while, I've had discoloured vertical lines on the right-hand side of the screen.
The lines appear on the built-in menus and test page, so not the inputs.
So far, I've tried the following, but had no luck:
- Reset the TV to factory defaults.
- Removed and reseated the ribbon cables going from the TCON board to the LCD driver boards (if that's the correct term?)
- Swapped the ribbon cables around - problem stayed and didn't move to the other side of the screen.
- Reseated the other cables going between the three main boards
- Inspected the mainboard and driver boards for any visual signs of damage - none found.
- Applied pressure to the various tabs connecting to the panel.
- Tapped / applied pressure to various ICs on the mainboard.
- Replaced the TCON board and the ribbon cables for both TCON > driver boards and mainboard > TCON.
- Applied pressure around the edges of the panel.
Still no luck unfortunately.
Here's some pics:
Any ideas? Is it worth me buying a used mainboard to test, or is it looking more likely to be the panel / something else?
I've attached lots of photos.
Thanks in advance!
Is this a good question?
