Re: Daytek F19AH
The line supply voltage is described in terms of its RMS value. The peak is 1.4 times the RMS value, and your incoming rectifier_bridge/filter_cap combo is a peak detector.
The DC at the large cap is present but no secondary voltage is derived from the SMPS. The possible candidates for this are SMPS controller, FET, SMPS transformer, output rectifier, output filter cap. The fact that the transformer is ticking suggests that the first three are still trying hard. If you get this same result with the video ("logic") board disconnected then focus your attention on the secondary rectifier(s) and filter caps.
