So my displays went out the other day on my Power play. I turned the game off then back on a d ay or two latter and they were wonky. So broke out the Volt meter and only getting about 140 volts on test point 2 so tonight I replaced all of bridge rectifiers thinking this would be my problem. But it wasn't same thing. So I broke out my book and this is what I found.
"The 173 volts AC that is used for the displays is converted to 230 volts DC by four 1N4004 diodes (CR1 to CR4)."
So I'm still learning could one or more of these be my problem? Is there a way to test them?
