I would like to see better assembly diagrams. The actual silkscreen has
to stay off the pads (and out from under chips, if you want to see it).

I suppose. How is that form better than what we have?
The PCB overlays could be the "assembly" prints that PCB already does.

Thanks, will do when I've

The last time I fixed a TV I resoldered all the joints on the nec board.
That's the round thing on the end of the tube. I found it by wiggling
wires. Try moving the wires on the horizontal deflection coils looking at
the screen with a mirror. Do not worry about the high voltages if it was

Back when dinosaurs roamed the earth, I used to fix TVs in a TV repair
shop. Maybe I remember some of what I knew then, but the jury is out
on that one.
I'd take a look at the driver transistor for the vertical oscillator,
or any of it supporting components. It sounds like the vertical sweep

Hi,
I'm fixing (or trying to) a TV for a friend, and wondered if anyone had
any wisdom relating to the following symptom.
This is a Sony BE-3D chassis, and exhibits an intermittent fault. When
its doing it, the picture is still visible, but collapsed (jitteringly)
