Gary, check for defective IC3(KA431Z) in secondary of p/s. RCA#212572. I
have this listed as defective like the C09 bad on other sets. The set only
blinks.

This vcr had diodes dpo26 and dp027 shorted,after replacing them vcr now
blinks on and off about once a second.the display blinks at this rate as
well.
i replaced cp007,cp008, ipoo1,ip003.
also ck'ed the resistors on primary side of smps transformer and all ck ok.
all voltages on secondary pulse up and down as well.
acts sorta like the ones that used that 22 uf bipolar cap in primary.
sometimes will stay on,untill you push a button, then starts cycling again.
any ideas?
thanks,
gary
