Title: help needed when playing games wells k7000 either shuts off or shakes
Post by: ctozzi on January 19, 2009, 07:29:35 pm

I am frustrated with my monitor that i just had a cap kit put in. When I play a game, the monitor either slightly shakes every few seconds, or goes out. I can hear the game in the background so i know the board works. Please help with suggestions. It is a wells gardner monitor with K7000 chassis 25". too much intensity on the bottom pot of the flyback transformer ?

You don't own a multimeter ?

I've got some basic multimeters (http://www.pealefamily.net/arcade/store/index.php?main_page=product_info&cPath=3&products_id=15) that I'm willing to sell.

The B+ is on the power supply on the Monitor board, you didn't change it you changed the power supply to the gameboard. 

If the B+ is too high or too low it'll sometimes do things like you're saying.  It could be other things too, like cold solder joints. 

A good first step though is to measure the B+.
