Turning the tv on the picture is red on the left side of the tv and it takes a long time approximately 30 minutes for the picture to become clear


Let's establish first, the power supply is fine. You have one of two problems now. Next, if the main board was bad, (contains all the RCA jacks and tuner connections) the TV would power up and shut down. Now we are down to the most probable answer. You may have an inverter board that is weak. There are lighted boards on either side( one left, one right). One is a slave board the other is master. If any of you Sony techs are out there.....let me hear your responses!

Screen will go blank with no audio. It won't shut off with either the remote nor physically pushing button on TV. Only way to get it to turn of is unplug it.


Hi,
This is a power supply problem, meaning either the power board has a fault or is detecting a fault from another circuit and shutting down. It shuts its self down to prevent further damage too the TV and prevent an electrical fire hazard. I know its probably something you don't want to know.....LOL but have a professional technician service the TV or take it back if its still under warranty.

When I turn on the tv I have very little sound and after a few minutes I lose that. Picture is clear so I don't think it is a connection problem.


Let verify first to narrow down to where the problem can be, attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.

"Unusable Signal"


Ok. PCB means Printed Circuit Board.
It looks similar to the picture down below. A part must have gone bad on your PC board. So, the RCA shop ordered a replacement PC board to fix the problem. It's an interchangeable part. All newer TV now have PC boards, which each one hold a different function.ebc3c7f.jpg

No Picture or sound


The lamp cover door was not secured tightly. Door does not "push" shut easily. Got a little rough with it and latched it shut, then the tv worked fine.

Vizio 50 plasma picture flicks off then comes back, sometimes flicks off to a totally green screen. warm or cold doesn't matter.HDMI connection


Replace the Z Sustainer Board, Part # 6871QZH044B and replace the Y Sustainter Board, Part # 6871QYH039B at the same time. If you replace one and not the other the bad one will end up shorting the good one and you’ll lose your picture within a week. You can do this work yourself by unplugging the unit and placing it face down on carpet (put down a soft blanket to protect the screen) and unscrewing the back of the unit (a power screw driver works great for this job because there are a few screws involved). The cheapest place to buy these two parts are: www.discount-merchant.com , or www.avextra.net, or www.ebay.com
