Vectored monitor display problem (pictures attached)

Hi,

 

My vectrex has a display problem -- really bright dot in the center and rays are drawn everywhere. I discharged the monitor properly and attempted to re-sit all the chips that are socketed. I checked all caps of the main board and the side board, and none is bulging. (Damned! In the process of taking the board out for cleaning, I broke the potentiometer that control the volume. Anyway, that's the least of my problem now.)

 

Any idea what's wrong with the monitor or certain chips? Thanks!

Looks like the brightness is turned up too far. Perhaps that pot is also broken.

 

Damned! I could kick myself in the butt for this! Yes, the brightness was turned up too far! It's OK now. I should have checked the obvious before doing surgery on my Vectrex. Well, I guess now I have a real problem to fix -- the volume potentiometer, which is tied to the power switch. Need to look of the ohm rating for the volume potentiometer and replace it.

 

Thanks!
