Blitz monitor with possible convergence problems -- what to do??
I scored a couple of NFL Blitz machines in an auction the other day. one has a WG U5000 with a dim picture and needs a cap kit (incidentally just like the other U5000 I bought last week!) and my Blitz 99 machine, uh, well..... the monitor has quite a few ailments.
judging by the chassis tray saying "REPLACE WITH K7500 CHASSIS ONLY" I'm going to assume it's a K7500. it needs caps, but when I throw up the White Screen, the entire screen is red.
it's also got a cool double vision effect that would work very well with those old school blue and red 3D glasses.
I've never mucked with convergence or purity before. I have hardly any money in it, so I figure it's worth a shot to learn how to fix it myself.
I tried dialing the RGB drivers up and down to see what it would do. turning red down/off gives me a blue screen, so I'm inclined to believe the red convergence is what's out of whack.
this tube's pretty shot too, real weak. I reckon if I can adjust it right though that a rejuve might help.
EDIT: I'm not a genius. I forget if I turned Green down/off when I did the Red -- screen should've been yellow if green and blue were on, yes?
