I have a Sony kdl 52ex701 the audio is ok but no video. Changes channels and everything ok except the video. Thanks for...

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.

Tcon board is your best bet.

Checked fuse f101 ok. I purchased a refurbished and solved the problem even though it has an intermittent issue that when it’s turned on for the first time it has a blurry screen for a minute or two. Then it works ok. I hear a humming capacitor till it stops and then it stops.
