Title: MK4 25" Monitor Green is out and image is slanted
Post by: testicle187 on March 30, 2012, 08:32:16 pm

I am not sure what would cause the green color to be out and the image to be slanted on my MK4 cabinet.  Is this something a full cap kit would fix?  Sorry if this is a bad question, I just don't know where to start.  The wires from the Jamma harness to the connector on the monitor seem fine.

Sounds like it's out of convergence. Pics?

I will get pics up.  Do I need pics of the chassis and tube areas as well as the display?

Can anyone help me identify the chassis?  I would like to send it off to get repaired, if anyone believes that is the problem...

looks like a u5000 or u2000
anyway just looks like green drive transistor is shot-most likely broken trace or dry solder joint on neck card

How would one go about fixing this issue?  I am guessing a chassis repair and cap kit won't take care of this problem.

you would need to remove the neck card cover and check for broken tracks and then use a multimeter to check the transistor
