This is a common problem. There are several capacitors on the power supply and logic board that are bad. Replacement of these parts has restore all units that I have looked at. On the power supply I would replace at a minimum: C14 - 4.7ufd 50v UPW1H4R7MDD C4 - 1ufd 50v UPW1H010MDD C8 - 100ufd 25v UHE1E101MED C10 - 470ufd 16v UHE1C471MPD C12 - 1000ufd 10v UHE1A102MPD
There are 4 others in the supply that were not grossly bad. C1 - 22ufd 400v EEU-EE2G220 C7 - 220ufd 25v UHE1E221MPD C11 - Same as C10 C13 - Same as C10
Logic board: E5 - 33uf 35v EEU-FM1A471 E6 - Same as E5
Part Numbers of replacement caps are Nichicon or Panasonic.
Note: Caps on the logic board are extremely hard to replace due to the internal ground plane.
Contact me if this is beyond your skills for possible repair.
