Rca 42in full hd lcd picture flickers

If the picture on your TV flickers, there may be a simple fix. Here are some possible answers and suggested solutions:

1. Your set-top box may need a simple reboot. Unplug the power connection to the set-top box for about 30 seconds. Reconnect the power and turn the set-top box back on.

2. Check all of your cables for a loose connection by tightening each one with your fingers.Flickers can sometimes be caused by bends in rigid cables, too.

3. If your picture flickers to a black or blue screen, you could have a bad set-top box. Contact your cable or satellite service provider about installing a new one.

4. If you still have audio, the flickering could also mean that you have a failing backlight.

For additional troubleshooting information, check out the chart at TV flickering for more solutions. I hope this helps!

Screen blinks and then goes out. tap on side and causes flickers

sure sounds like loose solder joints, look for them in the deflection circuit, just find the hard plastic encapsulated body with the thick red wire sticking out of it thats where usually the loose solder joints develop.

Picture flickers when T.V. is tapped on or struck.

sounds very much like a loose connection, i.e. a wire or solder joint, you could have a look around make sure everything is plugged in right, as for the solder joints id advise getting it proffessionally looked at as these rear projection tvs can be a lot of hassle if you slighty knock any of the 3 tubes,
