So, do you guys think this is a monitor or board issue? Ignore the fact that it's green. We were playing with the colors. These bars just start showing up. Im thinking it's a board issue. The monitor has not been recapped is a 13 inch wg 4600.

Thanks,
Tracy

 
It is hard to tell in that picture, but vertical bars usually indicates a problem with one of the 74153 chips. One way to test is to pull pin 39 of video decoder 4 high. That should flip the screen upside down. If it clears the vertical bars, it is one of th 74153s.

you have more than one problem. First take it into the color bar test and adjust the colors. The next part looks like a RAM failure intermittently, which could be caused by a failing power supply.
 
yep, know about the colors. It was adjusted that way so that the issue would show up better on his iphone.

thanks for the pointer...
