I recapped a ez20. Was getting no picture. Replaced the hot.now its blowing the fuse where the main plug on the game is(not chassis). Any ideas?
Thanks in advance!!
 
check your work again.

unplug the power supply.
unplug the PCB.
unplug the marquee.
unplug the monitor.

turn on the cab does the fuse blow.

if not hook up one thing individually at a time to isolate the problem.

this is where i would start.

no prob glad you got it working.

patience and checking your work is a must in this hobby.
i do it all the time before i plug/hook anything back up to two test.

you never know what you may have put in wrong something complex or something simple. it is easy to do.

I had no neck glow..found cracked traces then had to replace the mylar cap beside r479.final issue was a diode in backwards. D603.. Also capped it,with filter and b+ pot. 2 vr's on the neck board. Looks awesome now.
