Need Help/Advice For Sony PVM

post a picture so we can see it. 90% of troubleshooting is to see what's. its doing. you might need to do the solder grounds around the inputs if you lose a ground the signal goes crazy.

I can try to get a picture, but it's really faint, so I don't know if it will show up. It's just faint diagonal bands that crawl up towards the upper right corner of the screen, slow down, stop, reverse direction, and then crawl down toward the lower left corner of the screen. The lines themselves slope downward from left to right. I first noticed it on an S-Video source, but soon discovered it also affects the component video and RGB inputs. I haven't tried the regular composite video inputs yet to see if it affects them as well, but I'm fairly certain it would. The video, otherwise, has excellent color and geometry.

EDIT: Well, the video has excellent geometry except for the upper and lower portions of the picture being slightly more stretched out than the middle of the picture, but that isn't even noticeable unless you're looking at a vertically scrolling static image, so I'm not too interested in trying to fix that issue.

you might have a bad cable, that would cause it to have interference. check the solder joints around the inputs, if you are getting interference then you have a bad ground pr a cable. I would try that, its hard to figure out without seeing it.

I'd guess a bad ground is more likely, since I see the same interference from multiple sources using multiple different cables.

It does look a lot like RF interference, but since I get it from multiple sources, using multiple different cables, and in multiple locations, it seems to me like it's either being caused by something inside the monitor or it's coming in on the power line somehow. A bad ground would make sense, though, so re-soldering on all the rear connectors might be a good first step.

Haven't gotten my camera out to try to get a picture yet, though.

I would try that first all inputs share the same ground. reheat them and we will go there.
