Hello,I have a Hitachi 32PD3000 that went faulty. Upon investigation found that there was no front panel led and no standby rails (+5v & +3.3V.) Found Q104 on the power supply (type MPF7103) had gone open so replaced which restored the standby power, also found the PFC chip had also gone faulty on IC001 module.I'm now at a point where I have standby power but no Vce or Vsa rails and no signals from the PDP micro board, but I do have CPU-Go and PDP-Go from the Signal/ Sound Board to the PDP Micro board. From the PDP Micro board I do get PFC-go but missing Vce-go and Vsa-go signals.I can force the Vce-go signal and up comes VCC +5.1V and +12V but haven't tried the Vsa-go in case I might cause damage.I suspect that the PDP micro board is at fault, not sure what steps to take next to prove it. Any thoughts?Thanks.Mike.
