Television and Home Theater

Does anyone else have this problem? When using the HDTV connections, I get a green background and barely get any red or blue. If I switch to any other connection, the color is fine. I've adjusted the color scheme but it still has no affect. Has anyone else had this problem, if so, what was the fix. I pulled the back panel and found two possible circuit boards that could be the cause but I'm not electronically capable to test them. Any help given is greatly appreciated. I can be reached at [email protected], Thanks

This sony kp 61v80 made in 1999 was working fine.  Then I went to turn it on and nothing happened. No picture, sound , or any indication it's plugged in except the light. The standby light stays lit the second I plug it in.  It never flashes and just turns on the second I plug it in and stays lit.  No response to any buttons on the Tv or the remote.  Anybody have any ideas to save me from this insanity ?

Panasonic pt47wx42f

Mfg Date: July 2002

After power up, power light comes on for a few seconds, then shuts off and goes into steady 3 blinks mode. Any ideas on how to fix this? Hints on the forum lead towards replacing parts. Can someone share details including a service manual for the above TV model?

 Much appreciated
