Question about Digi Channel Master/tal to Analog Converter/CM-7000
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
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.
