Hopefully someone can help. Trying to find a replacement power supply board(module 4) for a LX2802. Usual problem with TR11 blowing. Replaced this and most of the other transistors(TR8,TR9,TR10,TR15,TR12,TR13,TR14) but still the board gives out no power. Got 240V going to it from the mains switch. I have the circuit diagram but have ran out of time
