hi..i have a daikin and it has problem to outdoor unit pcb board is dead no green led flashing
the terminal 2 and 3 has 24vac .and so i check input voltage is 240vac on L N ,,after go to L1 and L2 and after go to bridge s1nb60 if check to this point voltage is 700vac after go to resistane and zener <burned zener>i replace zener with same i think wrote c55 5.6volt and after go to transistor voltage regulator 2sc 3751 and 2sc1815 and go to transformer........i look all pcb for dc voltage and nothing.i dont see anything else. question is all right to here?
