Re: Delta DPS-214CP PSU no standby (Grundig TV)

With D902 cathode lifted what voltage does VCC pin of DDA010 reach. The internal charge pump should be outputting a voltage to charge C903. The internal charging circuit then switches off when C903 voltage reaches => 10.5V typically.

Do you have the B+ voltage on pins 4 & 5 of the DDA010

Nothing on the VCC pin and I believe I do get 325v on pin 5 Drain (but I'll double check tmmoz)
