GE 31GT659 31 Picture on right is vertically drooping

The T-con board controls the picture elements on the screen. Usually replacing this board will solve the problem. If you can touch the screen and the lines disappear and later reappear, that says the screen itself is defective. The only fix is to replace the entire screen.

If model listed is correct the problem is in power supply or vertical or horizontal circuits.

If cut off on sides (horizontal) and bowed on sides it is a pincussion problem. IF short top and bottom a vertical issue--if both it is in the power supply.

Model listed is rather old and parts may not be available for it.

Possible failure of the VERTICAL SECTION of the deflection circuit. It is possible that the areas related to the vertical circuit is checked , check for weak capacitors near the output vertical drive. Also a faulty vertical coil- deflection coil- can result in half picture.
A vertical signal test can confirm.

I think your Picture in Picture is on, but no signal. See if you can turn it off.

Make sure first that the picture is centered by using the remote control to move the picture vertically and horizontally. Use the round pad towards the center of the remote and push the button according to which direction you want the frame to move.

Yes, you have a bad convergence Ic--set uses two of them---have someone change both and adjust the set in the Tech menu--if you need more information or help email me [email protected]

The panel is almost certainly bad. The only fix for this is to replace the whole panel which would cost more than the whole TV.

I also am having the same problem. at first it only showed up after the projector was on for about 15 minutes. Now I get a purple vertical bar on the right of the screen. I also get vertical green bars spread across the screen.
Does anyone have a diagram of how this machine is assembled?

your problem is called blooming as you might be aware of very high voltage in tv. you can check 1 high output voltage fron power supply. 2 if it is ok then the problem is in horizontal section.you can check cap.in hor. section at last flyback transformer. hope this will help.

That is not a vertical roll from side to side, this is a horizontal rolling. if the vertical had a roll it would be going from top to bottom. This is most likely a coupling between the horizontal sync circuit and the sync separator circuit. Good Luck
