      hi everybody,

      I found the fault.Faulty components are pc236 and pc243,both of short circuit.

      But there are no values in my scheme.

        where are these parts used? Have not downloaded the schematics yet. If a bulk capacitor then it may not be required since there will be others on the same rail.
