Usually the syscon servo micro. Check the drum PG/FG line from the drum
driver IC for low ohms to ground. I desolder it hoping its the drum driver
IC but it always turned out to be the micro.

Subject: [TechAssist] Quasar VV2016W excessive head speed
> This Quasar VV2016W TV-VCR combo came in dead. Found Q523 (2SA564)
shorted. Replaced with ECG 290. That restored power up function. TV mode
works okay.
> Now when I insert a tape, it loads completely and begins to play,
however, the video head (drum) spins at excessive speed and the vcr shuts
down after about half a second. Then pushing any vcr function button has
no effect. Have to power off, then power up to eject tape.
> Any help on this one?
