Hi tobiastv, thanks for your help. I think the capacitor does not stay charged, because when I connect a bulb it does not turn on or I bridge it with a screwdriver nothing happens. the tv only turns on the stamby led in blue but nothing else. it can be the source or the main or the lamps. which voltages should check. the diagram I already have it but I don't know what voltages to measure to rule out the fault .thanks.
