If you have electronics experience - check the power supply and make sure you are getting the correct voltage to your inverter boards and main av board - also do you see any movement on the screen take a flashlight and shine on the screen - if you can see a dark image on the screen check inverter boards and power first.

thanks,

I have the same TV and what is happing is the TV has 2 recievers in it to allow the PIP, So you have a power pack gone on 1 reciever the other is working, Your set has 2 power packs,1 for each receiver.
I had both of mine go, 150$ a piece to have fixed, good luck.

Was the screen shrinking or expading prior to failing? Or do you here a chirping sound. If so check www.TvRepairkits.com for a fix.

Hi, The problem lies within the unit. You have a hardware failure within the board. The power supply board needs to be repaired or replaced. If you are a handy person, you can easily swap the power supply board.. If not, bring it you to local reapir shop, they will find the parts and replace it for you. I wish I had a better solution like an easy fix for you. Sorry, but on hardware failure, there is no easy fix. Thanks, Mike

It sounds like you have tried changing imputs " usually the issue". The next step is to see if it is still under warranty and get an estimate of how much it will cost to fix. Invest in a good surge protector.

Question when u loose picture do u loose sound also ? If so there is an 27Mhz xtal on the (SSB) small signal board that needs to be changed when it heats up it cycles out of phase. when it cools down it will work again till it heats up.

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
