Out of nowhere, printer will not power up. Only indication that it is getting power is the small green LED on the actual power supply "cartridge" is on. So I open it up to test the voltage, and notice a very faint clicking sound when the supply is plugged in. I test for voltage at various points and the last point in which I get 30 volts is the plug that plugs into the circuit board. So I have correct voltage going into the board, but nothing coming out anywhere, and a faint repetitive clicking sound.
Any clues, hints suggestions? I even tried jumpering the contacts of the power switch with no luck. Once it hits that board, I'm lost! The only contact between the board and the switch is a thin ribbon that plugs in to the board, but I can't measure the female "plug" to see if it is getting power.
