[IBMx32]

   Hello
     plasma pioneer about 4 year ago model is pdp-505pg it can use remote to control power on and standby as normally but problem no picture only sound
I have check PSU, the following that I check is:-
     VADR = 61 V
     VSUS = 222V
     and other have 16.5V,6.5V,Vstb 3.3V and 12V
     
    I heard this common problem is come from X-Drive  or Y-Drive  but not sure may be it problem with panel also when power on I here a litter sound as high frequency and heat sink it warm up so but I'm not sure there is high voltage come out or not or may be my panel is faulty.
