Working on a BZ UR started off DOA threw a big blue in now it powers up get screen image but tanks are missing and many lines are drawn to center when you fire

background and high scores look ok,

sometimes the aming box shows up, sometime it doesnt

any idea whats causing this?

my next step will be to reseat all the chips unless you guys have a better solution

thanks,
Brian
 
Doesn't sound like a monitor. Flip the test switch looking for errors. I had the same issue and in test mode it showed an L on the right side middle of the screen. Math error. Found the edge connector to the auxilary pcb had crap contact. Fixed that and all is good. Also test for 5 volts on that same board. I'm no expert by any means. Hope it gives you a place to look.
