| AOC | LE32S5970 | doesn't start. | Power supply board did not supply voltage to the main board. I found U9101 burst and unmarked. After replacing it with the PF6003, the power supply turned on, however, pulsing 12v. I found U9102 AND U9103 leaking. | I replaced the U9101 with PF6003 + U9192 = PC817 + U9103 = TL431. It worked 100%! | Ruizyn |
| SONY | XBR-52LX905 | It arrived with thick vertical red stripes in front of the picture and artifacts on the menu screen, then it stopped turning on and it kept blinking red stby 5x | The defect with the red stripes was the t-com, but even with a new card it started flashing stby 5x intermittently, so I cleaned all the tcom flats and it worked perfect, tested for 3 days. | Pedro Igor | |

| PHILIPS | 14PT3131/78R | Turns on the picture for 5 seconds and turns off (either in Av or Channel) | Memory | Re-record or replace (in my case I replaced it and it resolved) | DTEC-ELETRONICA-Massapê-ce |
| SAMSUNG | PL43F4000G | Turning off by itself for no apparent reason. | The thermal paste on the mosfets becomes very dry, so the heat generated by the mosfets does not pass adequately to the aluminum heatsink, the circuit current rises and activates the protection. solution, remove all the old paste and place a new one. This also applies to other plasma models. | Ferraz | |
| PHILIPS | 49PFG5001/78 | IT TURNED ON NORMALLY, BUT AFTER ON AVERAGE 33 SECONDS, after showing an picture, IT TURNED OFF AND STAYED IN STANDBY WITH THE RED LED ON, WITHOUT BLINKING, IT SIMPLY TURNED OFF AND DOESN'T TURN ON AGAIN BY ITSELF. SO EVERYTHING INDICATES THAT IT IS REALLY AN UPDATE. | SOLUTION WOULD BE TO replace THE NAND FLASH MEMORY ALREADY RECORDED OR UPDATE WITH THE FILE THAT IS IN 4SHARED FOR THOSE WHO HAVE A NAND RECORDER. BUT OUT OF CURIOSITY I ACCESSED THE PHILIPS WEBSITE External Link... < /a> and downloaded the software update that is tsound. | AND BY COINCIDENT I SAW THAT IT WAS AN UPDATE THAT SHOULD BE MADE IDENTICALLY TO THE AOC LINE, THAT IS, WITH THE FILE DOWNLOADED AND ON THE PEN DRIVE SHOWN ON THE TV, THE TV ON STANDBY, PRESS VOLUME +, HOLD IT DOWN, PRESS POWER AND KEEP PRESSED UNTIL THE STANDBY FLASHES OR OFF AND RELEASE VOLUME AND POWER AND THE TV DOES THE REST. DON'T BE SCARED, IT DOESN'T SHOW AN UPDATE BAR, ON THE CONTRARY IT JUST GIVES A FEW RANDOM BLINKS ON THE LED, AFTER IT GOES RIGHT THE TV TURNES ON BY ITSELF, REMOVE THE PEN DRIVE AND IT COMES IN BURN IN (GREEN RED BLUE WHITE), JUST ACCESS MENU AND CONFIGURE FACTORY RESET, READY, RUN FOR A HUG... | MIGUELTV |
