Does not turn on or light up the LED | Capacitors | Replace capacitors; c847 = 100μF 25v (can be 100μFx50v) + c842/843/835/864/865/877 = 22μFx50v (I used 47μFx50v capacitors and it worked ok) | Lucafer |

Turns on image blinking, oscillating, varying colors, voltage vs, oscillating. | Check that tsound is a voltage variation across the voltage doubler capacitors. | In my case I replaced all the 22μF x 50 volt capacitors, on the "hot" side of the power supply, carry out general resoldering on the power supply and readjust the "vs" voltage. This solved my problem. | arock |

Red stand by led turns on blinks 3 times | I measured the power supply voltages, the 16v voltage is missing, pa7405 fuse code 100, open and a 10.0a 76v I put 10a 250v smd, I turned on the TV the green LED flashes 16 times or more, tsound is sound but no image LED bar on the display is off , measure the board that powers the LEDs, the voltages are normal, this defect comes from the T-con board in short, I found the fuse 2a 250v smd open and capacitor c201 - 10uf 25v smd in short, I replaced it, solved it, the display came on, the image was ok | Defect resolved | Carlos assistência técnica PANASONIC |
