Question about Zenith Z32H41D TV

White Horizontal line across screen

I recently aquired a Zenith Z32H41D TV. The TV has a white horizontal line centered on the TV screen. Is this a common problem and does anyone know which faulty part is the most likely culprit? Any info would be greatly appreciated.

It is most likely the vertical deflection IC has overheated and lost its soldering. If you open your TV up, it is a 10-15 pin in a row IC sticking out of the motherboard attached to a heatsink. It should be labeled "IC451." Give it a wiggle, see if it affects the picture, You may have to resolder them in place.

The IC may be hard to find, look for a peice of metal that is sticking out of the motherboard, attached to a small chip. I fixed a samsung tv that had it in the middle area.

Can be a case of vertical collapse. If this is the case, then the vertical oscillator and/or the vertical driver circuit are faulty. .
