Hi folks, I have one of these for repair, it is stuck in standby,blue light on. It has a vestel chassis with the 17PW15-9 power supply. I think the power supply may be faulty, does anyone know how to check power supply,or overide the standby. Please help with any suggestions. Thanks Norman.

Its come to me now, stuck in standby can be caused by c877 and c878 both box type caps 15n 400v. But the fault which is causing most of this is Q837 suface mounted transistor type bsh103 which is connected to pin 8 of sg3525a control ic807. This transistor is in the soft start of IC807, let me know how you go on
