This is a vertical circuit problem that is either bad connections on the vertical IC or a defective IC. If you can solder, you can fix this yourself. Look for a small flat IC attached to a heatsink with about 9-11 pins. It may be marked LA7837 or something similar. Try resoldering the pins first. If that fails to resolve the problem, replace the IC. There may be defective caps in the circuit as well, but those don't usually cause complete vertical failure. If the picture does not return fully, update this and we'll continue on to the next step.

Write to or e-mail the manufature and tell them what your prolem is nomaly they have techs. that will e-mail you back. On units I have worked on in the pest this is all most always coused by a bad cap. If this is a ongoing problem with this modle the factory tech should be able to tell you whith parts have to be replaced and the exact location. hope this helps.

It is my guess that you have some intermitent solder connections in the Vertical output circuit.
Hope this helps,
