Hi.

Red tint was caused by bad or no signal in blue and/or green channels of RGB videfind o signal circuits, which signal may start from AV tuner.

To start, how did you know that the problem was AV tuner?

If the problem was the AV tuner, then the TV would have worked OK by using an external receiver or a DVD for example.

If problem got worsening, more parts may have been damaged in this time.

Most of the video signal elaboration is done by the main controller board. This and other parts must be tested at component level. That is the only way to find out where the problem is.

About the service manual, this is different depending if model is ending with TS2E or TS2U. The service manual is for the chassis, and not the model the manuals below are for this same chassis, even if the file indicates the 42 inches (boards are same), just choose between u and click Get Manual at the left:

TS2E

TS2U

regards.

You might have a bad B board. What's worse is that the power switch is connected to the Q board which works in conjunction with the B board. Replace B board, You can send your B board for repair to a company called modus link pts. They are the largest part supplier of after market parts and repair.

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).
