Battle zone has loud transformer hum and is not playing
Bought a battle zone caberet
when plugged in the start light led stays on solid nothing is on the monitor and the main transformer is humming loudly
disconnecting the pcbs (pcb power leds on) it appears to be a problem with the regulator/audio 2 board a035435
when that board is disconnected the transformer is humming normally
iv already replaced the main voltage regulator on it fixed nothing
cap kit is on it's way r29 resistor is a bit burned but it's valu is fine
the caps are original
any idea whats blown or shorting?
