The monitor was working fine for a while and then it started to get a video problem. It would show all vertical lines. I connected it to a different computer and then it started working again. Then it did the same thing with the vertical lines. It was like the horizontal transistor is bad or has a bad solder joint. Now the monitor will not show any video. I have no information on this and i don't know where to check for anything. Any information will help and so will a schematic or service manual.
Thanks
