Chosen Solution
Hey Guys, I have a KDL-46W5500 Sony Bravia which has just decided to turn on with lines appearing 10 seconds after power on
.
After some investigation I decided to take the back off and try taking out / putting back in the T Con Board inputs and strips/connectors
but to no avail. I am considering purchasing a new one off Ebay for about $80, but wanted to know if any of you fine gentlemen could advise if you believe replacing the T con board would actually solve my problems or whether you believe it to be the LCD Screen itself. I did try powering on the tv without the T con connected and the lines didn’t appear so I think that is maybe a tick on the replace the t con board list. Any help would be much appreciated. other photos of tv components:
Thanks, Joel
Hey I probably should have posted earlier. Replaced the main board and after that didn’t work, I figured it was the panel and just sucked it up and bought a new TV. Good news is now I have 2 main boards that I don’t need… Thanks for all the help from the people on this board, I really appreciated it.
@joel_h this does not look like a typical T-con board error. This appears more of a video processor error and could originate on your main board. Check that board and see if you notice any obvious damage and check all your cables to ensure they are not tore and are properly seated. After that I’d start by replacing the main board (get it from a place where you can return it in case it is not the fault)
Does anyone know if it matters if you use a tcon board that has the same layout as the suggested model (BN96-30068A vs BN96-30070A from samsung) . All other info(numbers) is the same on the tcon board. The former is suggested for 50“ models the latter for 65” .
If it recomends a specific model it will only work on that one. If it’s recommended for various models then you ca alternate. Sizes of screen will defer on boards to be used.
I have SamsungUN60ES 7100, with intermittent vertical lines, see picture, is this a T-con board? I already checked all ribbon cables inside may do it again
Ours is a Sony Bravia that is now over 10 years old. Several months ago we started noticing lines, especially on the left (our left) side of the screen. They’d go away after the tv warmed up. Then we started noticing it was darker on that side of the screen, but again, after the tv warmed up the screen would be normal. Then about two months ago it started getting worse and didn’t ever get completely better, even after the tv warmed up. So I watched some youtube videos that all talked about the ribbon cables becoming loose over time and to apply pressure along the top and see if that made it better, and if so, it was a loose cable and if you put electrical tape or something that would help keep the pressure, it would fix the problem. Hubby pressed along the top and sure enough, when he pressed in one spot on the left side suddenly the picture cleared up. Stayed good for about a week, then problems again, pressed again, fixed again. A week or so later, same problem, but this time when he pressed on it nothing got better. So I decided to take the cover off and look at it better. As I was pressing on the tops of the ribbon cables that run down from the top of the frame, for a minute it got better but then suddenly there was a wide white vertical line, with a thin green one down the center of it, running down the front of the screen, and it was perfectly aligned with one of the cables. So now I still have the dark side of the screen, and some ghosting, and some lines, but now this bright white streak/line right down the front. Another weird thing is that if the whole screen is bright (like watching a show set in a snowy place) then the darkness even on the left side is basically gone, but if the scene is dark at all, that side is almost black. I don’t know if it means that particular ribbon cable is bad, or if something is loose, if things need to be replaced or what. It’s very frustrating as it’s been a great tv. Hubby wants to just buy a new one, but even if he does I would still like to try and figure out this one as it could then go in another room.
Yes replace tcon board and it should solve your problem.
%#*@, just this evening my LG LED TV turned black screen. The sound goes on but the screen is black. But in the dark of the room I see flashes of TV light go on and off at intervals. I wonder if I have a tcon problem or the main board problem. Who has a lead? Thanks
Tcon board is your best bet.
