Monitor issues with pics - can you diagnose these issues?
Just got my monitor back from the shop and am struggling with two issues:
1. On the attract screen (most noticeable) but also on games like Solomon's Key (that have large single color fields) I am noticing broken diagonal white lines that scroll across the screen. Is not noticeable on games like Joust and Mario which are mostly fields of black.
2. When I boot up the machine, again on the attract screen, the top of the image is bent? Which means I need to grab my mirror and my non-conductive alignment tools and adjust the horizontal hold until it looks perfect. Which then the next time I boot it up is bent again. Note: this is the Rolling Thunder cabinet which has speakers right under (and next to) the screen. Speakers are shielded but those are two magnets that are pretty close to the monitor?
Note: everything looked great from the signal generator at the shop - could this be a PCB (19 in 1) issue?
