SVGA monitor white diagonal lines
rampy:
That's visually close to what I had... does the image still look ok with the brightness cranked? If so it might just be the "brightness range" inside the case (danger/warning the insides of a TV is a dangerous place to be poking around if you don't know what you're doing - and I don't know anything about TV repair - YMMV) which effects teh range/sensitivity of the outer "user" brightness adjustment knob...
I dunno... I had trouble finding useful info on the subject... is there a usenet forum for TV repair that might have a FAQ or could trouble shoot that?
FWIW or comparison's sake... here's a picture of my monitor with the lines...

What you are seeing are retrace lines. The beam should be turned off as it returns to the top of the screen. If something causes the beam to remain on, you will see those lines.
causes:
Screen or master background/bias control.
Powersupply / B+ line or loose neck board.
Blanking circuit failure.

Here is a good reference.

Chapter 11 talks about the problem.

Thank you.. I hope that helps the other gentleman's problem too... I thought that is what I was seeing (retrace lines) but if you've never seen em before, how do you know what to call em... so thanks for positively id'ing em... In my case I believe that I probably loosened the neck board, and then subsequently unloostened getting it back into the cabinet...

Those look like the same lines. When I crank my brightness up, they go away.
