Hi

I have just aquired a Digimess SM5020 bench power supply there is no power to the outputs, i have checked all caps and they all seem ok can anyone guide me which area i should be looking in to find the fault.
Sorry not sure which part of the forum to post this but i guess you TV guys might know.

Many thanks
Vic
