oh okay...I thought you had an MEI CashFlow with the plastic cashbox.
Problem with those ones is a plastc prism inside that gets dirty and the fix is to just run them in a dishwasher upside down.

You have the much older WBA bill acceptor....there's no prism on these metal cans.
They're built like a rock and will last FOREVER...these metal acceptors and cash boxes are good if you maintain them but there's no way that it's the cause of your present problem.
I will still say that your main problem is the power supply box but I haven't ever heard that a bad power supply will shoot off a red led on the MPU.
Normally, the red led on an mpu lighting up means that something on the MPU went bad...hopefully it's just the software...that's easily replaceable and not costly as a new MPU circuit board.
SHop around for a power supply....you're going to need one soon anyways if you plan on keeping this machine.
The caps dry up inside these machines from the excessive heat, poor, cigarette smoke clogged fans, and die off.
The fans motors work too hard drawing too much amperage trying to turn the stuck fans and kill the power supplies.
Check and replace your cabinets' fans too...make sure they spin freely when powered off....should not be any resistance.

Thats not a wba its an old mars bill validator there cash cans are known for destroying themselves. If it was my machine i would start shopping for an mei or a uba. The red led is the cpu reset almost anything can cause it to blink or be solid.

You're right Retro!
Those had the small chrome pushbutton on the box and the metal lid flipped upwards.
I had some of those ZT DBV's w/the red leds a long time ago.
