Epson ELP-3300 schematic needed

By Reynolds - usenet poster

Customer sent in dead unit, I managed to fix the lamp power supply, but the
unit is now lighting up a blue screen with no response to controls or input
signals. I think it's something else in the P/S, but I need to know the
output voltages so I can determine which one is dead. TIA...

I have a similar projector also with dead PSU however mine is an
Infocus LitePro 580 ( which is the same as the ELP-3000). The main
board is the same but the PSU is different. It is made by
Panasonic-MKE and uses a hybrid Mitsubishi device that is obsolete.

As I remember the ELP 3300 uses a Sony power supply but the main
projector board is the same. The supply rails are 5V, 12V and 18V.
There are two 12v inputs A and B. When run on a bench supply these
were tied together.
