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 | |

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 <a href=\"https://electronica-pt.com/su/1w\" rel=\"nofollow\" target=\"_blank\">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 |
