I'm finally fiddly effin' with my Qbert machine and have run into a brick wall...
I had no 5v whatsoever so I did a Riptor p/s kit, recapped and re-xisted. I also replaced both of the big blue caps on the p/s board, since one of them was scorched.
Reflowed all of my connectors and reflowed cold solder joints on my filter board, a few were bad.
I also replaced both bridge rectifiers in the brick since I had gotten a bunch of extras and I figure it was good insurance.
STILL NO 5V-DC!! I'm up to 1.8v-dc now, the LED for the 5 glows dim... All three other LED's seem good and are bright as hell.
Adjusting the pot on the power supply doesn't affect my voltage, I replaced it with the kit. Ohming out the 5v adjustment pot it has smooth action and gradually increases with no jumping around.
PLEASE HELP! What do I need to check next??
