The screen controller board has failed. It's the one that has one or two flat ribbon cables connected to it

The set has failed to come from standby to on fully---could be the power board but if it will not power off usually it is elsewhere.Time to have a qualified shop take a look a get a estimate.

I'm having the same problem with my RCA. I was told it is probably a loose ground wire. GOOD LUCK

buy a new set as part needed alone will cost more than the new set will.

Video board defective....replace

bad capacitors on power board.

If you have a wall mount kit, it is fairly simple. You just find the place that you want the tv to go and find a nearby stud to install the mount. After that you will want a second person to help with either holding the tv up or screwing in the tv to the mount. There are four screw holes in the back of the tv to screw through the wall mount plate into the back of the tv. Check to make sure it is stable, then you have successfully installed the tv to your wall

Some people have been able to temporarily get the set to work. Unplug the set for an hour or so to cool off. Plug the set in and start it. Sometimes it will work for a short time.
THIS IS NOT A FIX. This will show that heat can cause the part to fail.

If this set is under warranty you should return it to get it fix/replace. If not then; This sounds like the power supply board is failing. The electrolytic capacitors on the board may need to be replaced. IF YOU KNOW HOW TO WORK WITH ELECTRONICS REPAIR(soldering ) or have a friend with knowledge/skill you can fix it. >Unplug the set and any cables. >Remove the back cover. >look at the capacitors on the power supply board. If the top of any of them are bulging up then that is a problem. >You will have to replace ALL the electrolytic capacitors except for perhaps the large one. >Disconnect and remove the power supply board. Handle by the edges to prevent contaminates and static electricity.> Use ones with the same farad rating > Use ones with the same or higher voltage rating> Use ones with high temperature rating> Install one at a time to prevent mix-up and keep the polarity correct. > Leave a space between the PC board and the bottom of the capacitors for expansion. They heat up.> Replace power supply board and reconnect cables..> Replace back cover. THIS IS AN INDUSTRY WIDE PROBLEM AFFECTING MANY COMPANIES AND PRODUCTS. One source for some good capacitors is NTE. Try nteinc.com for a local outlet.You can also search for other sources. Some companies even sell all the capacitors in a kit. Total price of parts should be < $20.00

Yes you can replace the power board but if the capacitors have not been replaced they will eventually fail also.

If the power supply board is not the problem, you can consider replacing the inverter board.
