Hi there,
Recently I had an issue with vertical coloured bars suddenly appearing on the screen of my Sony KDL-42W706B. After a bit of reading it seemed possible it was the TCON board, so I replaced it. However that did nothing. So then I tried replacing the LVDS cable (between the main board and the TCON board) which sorted the issue - result!
Skip forward a month and the same issue has appeared again :/ - vertical coloured bars on the screen (see attached photos - one with no input, and one with a TV channel selected).
Does anyone know what may be the cause? Has something caused the LVDS cables to malfunction? Or is it coincidence and replacing the LVDS cable again is the way to go? Or was replacing the LVDS cable a red herring that didn't really fix the issue (even though the TV was working perfectly for 4 to 6 weeks)?
I know it's probably difficult to suggest the issue / fix without more information and/or inspecting the TV, but was just wondering if anyone had any clues before I spend more money on it (or buy a replacement TV in frustration!).
Thanks in advance!
