Mine does the same thing. Was told by the TV repair guy it is a bad control panel.

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. The question will be, is the part still available? Before paying a TV repair person $75+ to diagnose the problem, ask yourself if you're willing to pay $250 minimum to fix this particular set. Also keep in mind that most TVs that old have a very limited number of replacement parts still available. Normally it will cost at least $75 to have the set looked at by a repair shop (diagnostics). If the part needed to complete the repair isn't available, you won't get that money back.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here.

Please let me know if I can be of further assistance.

Chances are there are cracked solder on one of the boards. This is a common problem with Gateways. If you're handy with soldering then this is an easy fix.
