Usually blink code on front gives direction but first thing to do would be to determine if surrounding sustain boards are causing draw on power supply by disconnecting them one at a time from power supply. y is on left looking from back and x is on right looking from back. if led goes solid with either board disconnected check supply voltages and if come up and stay up replace that board. if no change then you would need to verify vs on command coming from logic main to power supply. should be labeled on power supply connector and should be 3 volts. if present replace power supply if not present verify if logic main board sitting underneath signal board has one solid and one blinking led on if verifying normal operation and if so replace small signal board
SOURCE: Power Problems - won't turn on
first thing to do is determine if there is a blink code as that gives a direction for t/s. regardless, what you should do first is offload the y main and x main sustain boards from power supply one at a time as there is a common issue where these boards can cause load on power supply and if voltages come up with either one offloaded that board should be replaced before proceeding. if y main is the issue there is an upper and lower buffer board to left of that board and also should be replaced at same time as 3 boards complete a circuit and replacing one could cause damage to others.
