Hello techs,
This combo came in dead with a tape stuck.  When I plug it in the power
light flashes six times.  I unloaded the tape and cleaned the sequence
switch and now when I plug it in the loading motor and the drum motor both
cycle, the B+ comes up, it degausses, the other low voltage supplies are up,
the SCL and SDA lines have activity - 5vpp on the scope, the power light
flashes six times and then it's dead.  There is never any horizontal drive.
Pushing the power button makes the LED flash 6 times again.
   Now as I write this I remember a VCR I had a while back that was flashing
like this.  The fix was to reset the micro by holding the power button on
the remote for 7 seconds.  Well I tried it and It comes on!  Great, it works
now and plays tapes and the A/V jacks work but I only get blue screen when
using the tuner so I guess it needs a tuner now.
