im sure a new analog board will fix the problem. but i dont see a failed vertical IC causing the loss of horiz scan/HV, which results in a blank screen. Then again, never know.

the HV/video circuits are seperate from the vertical circuit, so a failure in the vertical circuit alone would NOT cause blank raster in that analog board. the horizontal line you had the beginning, yes, it would cause that. but that would be the extent of it.

however..... if the vertical IC shorted, its possible that it took out the 12v supply to the analog board, and THAT would cause the blank raster.... that voltage comes from the power supply, labled as the "sweep" voltage. on the red wire. probe this to verify the presence of 12V. if 12v is missing, you will have a blank screen with no sweep.

but without a scope, you cant probe the video, horiz and vert drive signals to make sure they are present.
