Re: Sony KDL-55EX500 solid green screen

I’ve tried wiggling the cable/connectors and when it seems like it’s working, the screen goes green again later on. What do you mean by taping? Like just securing it with tape?

Re: Sony KDL-55EX500 solid green screen



I gave this a try today and cleaned the cable ends and connectors on the T-con board and main board with rubbing alcohol. The intermittent green screen still shows up.

I did find one solder joint on the T-con that looked cracked so I added more solder but that didn't help either....

I have a Sony KDL-55EX500 which shows a solid green screen and I haven't been able to diagnose the problem. I was able to find a repair manual online and read a few forums on tv repair which pointed me towards it possibly being an issue with the power board or T-con board. Bad electrolytic capacitors seemed to be a common theme so I tried replacing all of the ones on on the power board, but that didn't fix it.

My next step was disconnecting all of the cables and reconnecting them. That helped a bit, showing a normal screen most of the time, but still switches back to solid green...
