> RCA VCR vR678HF (on SM with 676HF)
> Problem -No power.
> Found Main filter cap 100m 200v blown open - Replaced. Seem to recall one
> other small cap that ESR'd bad and changed.
> When first plugged in- would come up "BYE" in display and shut off. Could
> turn on and get startup menu. Could insert tape and it would play .Could
> also use tuner.
> If I hit Eject, unit unloads and may or may not eject tape but- power
> shuts off and display goes blank. Try to power on and it flashes on and
> off - coming up and shutting down.
> So I replaced regulator IC (u4614B). Did not make any difference.
> May have taken power surge.
>
> All Ideas welcome
