Question about Sony KV-20VM40 20 in. Combo

1 Answer

Picture flicks on and off

I have a Sony tv - it is approximately 7 years old.
About 3 weeks ago the picture started flicking on and off - just for a few seconds. On some stations I can watch an entire programme without problems, on others the flicking is every few seconds. If I use my VCR I get the same problem. I have had the cable guy in and he says it is not the cable, but the TV.
How can I fix this?

Same problem with sony ke-p42m1


this might be a bad or temp sensetive tuner, why don't you try hooking up a dvd player to your video jacks and see if the problem is present while watching a dvd disc. If it doesn't then you may have to replace the small signal board(where the cable or sat feed hooks up to the tv).

change out the LVDS cable (the cable that go from the control board to the main board) and it should resolve your problem. If your TV is still in warranty, call 1-877-MY-VIZIO and they will set up an in home repair for free.

Channnel keeps flicking like your changing channels with remote


when you say flickering??? are you saying the screen goes black and comes back on?? does the sound go out at the same time and comes bag on with the pic ? Is the sound there when this happens but is distorted. Is the pic blacked out or is it greying out with lines and twisting?? Need more info please as if its blacking out and the sound goes with it it may be going into shutdown. If the pic is getting kinda greyish with it twisting and the sound is there and ditorted then the tuner could be bad
