If it's a Gateway XHD3000, I may be able to fix it for you
I believe the problem is in the same board that causing the full strobing screen problem.
Cost is 150 to repair the problem board if it is fixable. No charge if not fixable.
You will have to pay round trip shipping for the monitor and power supply to Pennsylvania.

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!

32" 32lc7d after a few minutes, flickers, then goes dark.


There are no fans in this model but it looks like either the backlights in the screen are breaking down after they have warmed up or a problem in the inverter board, again part of the driver circuit breaking down after a period of time. They inverter boards can sometimes be replaced seperatly but usually come with a new screen which if the backlights are at fault then the screen would need to be replaced.
