I have an older model Hitachi 32" ultravision CRT tv. the video just collapsed into a thin horizontal line (about 1/4"). Video is fine. Any help would be greatly appreciated. Thanks.

The vertical circuit gets too hot and burns out the a trace in the circuit board. It is a large, component to the circuitry with a heat sink and it is OBVIOUS to find. (char marks). If you know how to discharge a tube television, then you can bypass the trace with a piece of wire :P Note: I had to fix this problem twice, first time the fix was to just re-solder it, but it broke again a year later. After that the whole trace burned out and I just bypassed it with a piece of wire. It has worked ever since! (4 years and counting)

TURN IT OFF AND DO NOT TRY TO USE---if a thin line left to right in middle of screen it is vertical problem---the set should shut down but even seconds count here--this can burn a mark on all three picture tubes instantly and it is permanent.

Problem if small line left to right in vertical circuit.

Let me know what you know and I will try to help--I know these sets very well.
