Hi folks, newbie here. I have this nice little portable TV that was working 100%. Until it wasn't. It is totally dead, no video, no sound. The pilot light doesn't light up. I have checked both fuses and the on/off switch, all good. There is voltage leaving the secondary of the power transformer. My skills do not extend to diagnosis at the component level on the boards- nor do I have much in the way of test equipment. I don't have a schematic, either. I don't have the accessory battery pack for this set, so can't tell if the fault is in the AC or DC power supplies. Anyone got suggestions as to what I can do? I hate to bin it, but at the moment it's a doorstop.
