I suspect J101 connection, F114, and BR1 and or broken thru holes at BR2 or C7. Check your DC voltage at the anode of D1 this should be 18V straight off BR1, if the voltage is missing there the issue is BR1 or further back. LED6 also comes directly off your bridge, for this to be out BR1 is not producing voltage. I would measure the resistance of F114
