[RESOLVED] Sony 75" LED TV sometimes flashing patterns and colors
The TV after a few years of working fine, has developed a problem.
It sometimes (but only sometimes) flashes patterns, lines/colors on the screen. The pattern and nature of the problem does not look exactly like any of the other examples I have seen online which is why I am making a new post.
The details are the following: The TV usually works 100% normally when I turn it on. Only after a few minutes of watching TV, does it start flashing patterns/lines on the screen, and it does not stop until I turn off the TV. This process has repeated for a couple of weeks now. The sound always works so it is just the video. I have tried leaving it unplugged for a day, factory reset, etc. Sometimes I can watch TV normally for only 60 seconds before it breaks again, other times it lasts more like 10-15 minutes after turning it on, but it always happens.
I am attaching a video example of the issue so anyone may be able to help diagnose. From what I have read online it might be T-con board (cheap on ebay), maybe the LVDS cable, possibly the whole panel (not worth fixing), or the main board.
I found this link with the parts available for my TV, and I found the t-con board, but I am not sure which is the correct LVDS cable since they show 4 cables available: https://sony.encompass.com/model/SONXBR7...
The TV model is actually XBR-75X940D (this site would not let me input that as the model)
Does anyone have an opinion on which part it might be or which steps I should take to try to resolve?
Es esta una buena pregunta?
