My Star Wars Upright has some pretty loud hum that I'm trying to get rid of. I have consulted the two threads below and found some common things to check, but I have done all of that and still have the hum. The hum is at a constant (somewhat loud) volume regardless of what I try or how the volume pot is adjusted.
Star wars hum...Fixed!
-Replace Big Blue
Star Wars HUMMMmmmmm....
-Unplug Marquee Light
-Replace Big Blue
-Dirty/Bad Edge Connector
-Dirty Fuses / Fuse Block
-Recap AR-II
-Dirty RFI board
**************************************
Here is a summary of what I have done:
-Recap ARII + new regulators
-New audio amps on ARII
-New Big Blue
-Remove marquee bulb
-Unplug control panel
-Unplug coin door
-Unplug monitor
-Remove RFI board
-Clean/squeeze edge connector (no effect)
-Swapped power brick (with new big blue) from another game that did not hum
-Tried different speakers
-Unplugged test switch / volume control panel - hum remained constant but game volume increased
Nothing changes the hum even a little bit. Is it worth it to recap the PCB? Are there any other things to try?
