Providence Village, TX
I have a POTO that has a speaker hum when turned on and doesn’t seem to actually boot up. I added a video, any ideas where to start?

Quoted from pinmike:Check the main fuse the one in the cabinet and see if it is blown
All fuses are good, I ohmed each one of them out in the back box.
Quoted from pinmike:Was the game working before? Or did you just purchase the game?
I just purchased this game, It was sitting in a storage building for years and was worried about the sound when I turned it on. There is alot of work that needs to be done to this pin, the main board has corrosion and there are fuse clips that need to be replaced on the power board. I didn't expect it to actaully fully turn on but wondered if anyone had a cule of what might be making the speakers sound like that.
Quoted from ccbiggsoo7:main fuse isn't in the backbox
My bad I was thinking main fuses in the back box. The main 8A slow blow fuse Ohms out good as well.
Quoted from ccbiggsoo7:I have owned prob 10 data easts, not 1 yet that didn't need a new power supply.
Very true and battery corrosion is even worse

Those bad fuse clips on the power supply are causing the power up problems.

Any idea what the part number of those fuse clips are? I will get some on order today!!

I don’t know the part numbers but when ordering just type in data east fuse holder clips in the search box and results should pop up.
Your power supply in the back box is the likely culprit. Check the output of the power supply with a meter looking at the +5 volts which I suspect you do not have.
Test Point 1 (TP1) on Power Supply is +5 volts DC
Test Point 2 (TP2) on Power Supply is DC Ground
