Power 48v check

Either the power supply is
not generating a proper 48
Volts or the controller board
is not detecting a 48 Volt
output from the power
supply board.

1. Make sure the power supply
board is correctly connected to
the controller board.
2. Power on the printer. If the
message appears, do the power
supply operational check (page
195). If the power supply fails the
check, replace it. If it passes the
check, go to the next step.
3. Power on the printer. If the
message appears, replace the
controller board. Record the
message and return it with the
defective board.

Without seeing the board or the schematics, I can't say that replacing the power supply will fix your problem. There could be a short external to the power supply that is causing your problem. You can buy replacement parts from or

I have an Intel D865GBF motherboard in my PC, which stopped working. I replaced the power supply because there was no power to the board. Now I have power, but when I hit the power button nothing happens.

The exact same thing happened to my D815EAA2. In my case an overheating power supply destroyed the board. Do the following:

1. Check the power supply you replaced it with works on another system.
2. If it still doesn't work with your board, the board will need to be replaced.

Need info on component 3071 on power supply board - burned up.

Its been a while since i worked on that power board. But I believe you are refering to the orange diode that runs into the single connector for the video board next to the power supply. I replaced mine with a 1n914 diode after replacing the 2200uf lytic cap and the tv fired right up.
