[bviking2002]

Please help. I need service manula or schematic for my defective tv. Sony Trinitron KV25FXR20. Problem is pic will go off and on after sometime. Audio is ok all the time, although soft. Video out, however is ok all the time. I also need datasheet or pinout for Sony IC CXA1464AS

Thanks to all who can help me.

Chances are your CRT has weak emision on one or more colors. I have had prety good luck restoring these tubes with my sencore tester. they seem to last quite awhile afterward anyway.

Hi, most likely the trouble of your tv is at the tuner/IF section that needs to be resoldered. Please upload if ever you found a schematic diagram of your tv.Thanks and God bless!
