Re: Sony Trinitron display malfunction. HELP!!!

Jack Posted Feb 03, 2005, in response to:JP

Hi JP, I am not sure if you have fixed your set yet, but just in case you are still trying here is some info. Most of SONY Trinitrons from this series have common problem with bad solder joints on power supply board. I have replied to many people here who have similar problems. If you do a search on this forum using SONY TV or KV32 as keywords or my name you can find many of my posts for people with similar problems. It sounds like you have a failing joint on one of the components in Horizontal Output Transistor (HOT) Drive circuit. I would recommend not turning on your TV until it is fixed, because it can lead to failure of HOT and other components due to arcing on bad solder joints. A good starting point would be obtaining a Service Manual or at least a schematic. Again, I have already replied to other people with info where to download it on the web free of charge. Good luck, Jack
