Hi Ifixit, I’ve got a Panasonic th-p42ut30a plasma tv that has a fault with it. The standby light is on (red) but it doesn’t come out of standby. Pressing buttons on the remote don’t do get a reaction from the TV and pressing the buttons on the side of the TV itself don’t get a reaction out of it either. No blinking lights or anything to help diagnose the problem. Just sits there with a red standby light. I’m not scared of getting my hands dirty by opening the unit and testing voltages. I just need some general help with what board to test or if possible, a repair guide on the unit. Any help would be appreciated!
Paul, follow the trouble shooting algorithm attached to this answer. It does sound like your trouble is on the Main AV input board.
Hope this helps, good luck.
TH - 50PF20, Power turned on (indicating green light, and a quick flash of power) But the buttons on the actual screen were locked . We had to unlock it by pressing the volume up 4 times, then input 4 times, then press volume down 4 times and then selected Enter . This unlocked the buttons on the TV it self and then we just selected the input.
