Hi Metthew,
Most probably the TCON board in your tv is defective. Please consult some qualified service technician. Most of the time the company service centers ask you to replace the entire LCD panel, which is an expensive affair. TCON board is a small part of the panel. and its job is to distribute the picture information across the LCD screen. Good luck.

Vertical rainbow stripes on my GB color


I would say that the screen is causing the lines in a gameboy colour the lines are not the same like it would be in an orginal gameboy the one with the four batteries. Lines in gameboy color are the screen issues then the whole screen would have to be replaced on the GBC then.

Screen went black with a vertical rainbow line down the middle


Failue of the vertical section, could be the drive, the power to the section or even some discrete componets. Unless you are familiar with electronics , get some help to ceck out on these circuits, could not be major but to get themain culprit will require good probing.

Picture shows only about a 2-3" blue,green,or red vertical line down the middle


If your seeing vertical line across the screen you need to check the components in the vertical stage as well as the vertical IC could be bad, or the yoke could open.
Also check if any voltage reaching the vertical stage.

Good luck.

Tube turns on nothing else does


If the Tv turns on (power supply is ok), screen lights up (inverters are ok) but don't get a blue screen, menu options, source options, or audio, it's most likely the main board (aka Motherboard) is faulty. If a DVD player is hooked upto the TV, check whether you can get audio from that (change the source using remote), in such a case it could be a problem with LCD Interface board. My $3 is on faulty Main board.
