Panasonic 50PX60u,when plug the AC cord, it clicks 2 times, then third, looks normal. but when press the power button, the fans turn a second, then power off, LED blinks 5 time then repeat.
From the serive manual, it's the SOS 5V D board issue. I got another TV set, same model,works, to replace the D board, PA board, DT,DG, H, SS, and finally the P board, but still the same.
Looks like the the indication of 5 Blinks is not D board related. Finally I disconnect the vda connector(SS44) from SS board to C4 board, it could power up! but only upper half screen has pictire.
The lower half is dark (becuase there is no vda (75V) to C4,C5,C6), I uspected the there was something wrong with C4,C5,C6 board, I replaced all of them, connected the VDA(SS44), but still the same problem. I have no idea now, the only I can suspect is the Panel problem.
