budman2, sounds like one of your boards in on the fritz. Take the back of your TV off and take a couple of images and post those with your question. Use this guide for that. It will help us to identify the layout of your TV and let's us take a closer look at your boards. Right now it sounds like you are having an issue with the H-board.
Try to access the self check first:
How to access the self-check screen to reset the unit.
Select a television channel, and while pressing the [VOLUME ( - )] button on the main unit, press the [OK] button on the remote control for more than 3 seconds.
How to Exit the self-check screen
Press and hold the Power button on the TV for 5 seconds or disconnect the AC cord from the wall outlet.
TV volume down & OK on remote only does a basic IC self check. It does NOT Reset the TV.
It does not clear channel programmed settings, picture settings, channel labels, LOCK mode settings, or password.
Using this method, it shows the unit firmware version (Peaks 1.050 and GenX 1.00) and it checks IC communications ONLY.
Let us know what you find.
