There is a dark/black area along the left 25% of the screen. The picture doesn't show exactly how bad it looks in person. Not sure what to check/fix in order to remedy this? Any help troubleshooting this would be appreciated.

The monitor is a 25 in. Wells Gardner, possibly medium resolution? I couldn't find the model # of the chasis anywhere. Can anyone tell me which it is?

Pictures are attached or can be seen here:

Thanks!

you have a k-7000A chassis made by zenith, you could try to recapp the thing then see how it looks. flybacks are currently not avabile for this model.
I belive the model would be 7101 or 7103 or 71xx.

Right on all accounts. Cap kit. Had several K7000s do this exact same thing, cap kit worked every time.
 
Awesome, thanks! I've rebuilt tons of 19in. standard res. but not a lot of fooling with these. A cap kit will be no problem. I'll get on that and post back a follow up! I appreciate the help.

Well damn if the monitor didn't go completely out before I could get a cap kit in it. Parts are on order and should be here this week.... The flyback still looks good and it appears to be gong into shutdown/protect mode upon power up. If I disconnect power from the monitor and power up the game, it plays blind. Upon reapplying power to the monitor, you can hear it start to power up, then it shuts down. Think I'm still gonna be able to fix this with the cap kit? Hopefully just one of teh caps on the B+ line is out of spec and the monitor circuitry is shutting down?

Any additional tipe or thoughts y'all could throw out there?

Thanks!
 
I have fixed several with just a cap or two but usally do a full cap job when its out. might also be the voltage reg. if the caps dont work.
 
Yep, start with the complete capkit. VR is next, if that does not work.
 
OK, Cap Kit and some double checking all connections & joints got the NBA Jam monitor back up and looking like new! Thanks for the help y'all!

Good work. FYI, the specific symptom you had in the first post is usually a bad C57 cap. You can shotgun 'em all, but it'd probably be fixed by replacing just that one.
