we have repaired a lot of the Funai DVD/VCR units on full warranty and on parts
warranty. Dont expect to see any off warranty, except maybe for cleanings, as
the stores periodically dump them for less than $100. If your Hitachi is a
Funai, there are several common problems. One is caused by cassettes with doors
that stick or reel brakes that dont release. The loading motor brings the
cassette in and down. Then the capstan motor takes over the tape threading
operation. If the tape does not come out of the cassette easily the capstan
motor stalls. The capstan motor driver IC, on the motor, overheats and burns
out. The IC is not available so you have to replace the motor assembly.
Inexpensive, at least from Funai, but you may have to do a lot of fine
soldering to replace it, as they soldered lots of cables in rather than use
connectors.
The other problems are caused by noisy mode switches. It has to be replaced,
not cleaned, or it will malfunction again after a short time. The confused
micro runs the loading motor and capstan motor until one or both burn out.
Again you are replacing the capstan motor, some of which contain the loading
motor driver IC too, and maybe the loading motor, as well as the mode switch.
The IC that was replaced before took care of your tuning problem. The A/C head
had nothing to do with that but the servicer probably noticed a problem with it
when checking it out.
