Re: NS-LCD32 - Power Cycling
I can't tell if this power supply uses PFC or not? If the large cap is around 450V then it might use PFC? If PFC is present, then the VDC across the large capacitor should be around 390V when the SMPS is working properly.
If the large filter cap is rated at 250V, then there is no PFC.
For the 1 second on/off, check all your diodes to see if any are shorted. It shouldn't take more than 10 minutes to test every diode on the board (including any on the heatsink).
