OK I DID IT I WAS AFRAID TO OPEN IT , BUT IT IS SO EASY IF YOU DO IT LIKE I DID IT , FIRST UNPLUGGED EVERYTHING WITH THE TV , TRY IT IN OPEN SPACE AND WITH LIGHT , UNSCREW ALL THE SCREWS FROM THE BLACK COVER IN THE REAR OF THE SET ONE BY ONE THE USUALLY HAVE AN ARROW MARK POINTING TO THE HOLE, INCLUIDING IN THE BOTTON OF THE COVER , ALSO UNSCREW THE OTHER SCREWS FROM THE RECTANGULAR COVER TOO THE ONE THAT HAS THE HOLES FOR THE VENTILATION OF THE POWER SUPPLY, SO AFTER THA IT IS DONE , PULL OFF THE ONE WITH THE HOLES AND THEN THE BIG BLACK COVER PULL IT FROM THE MIDDLE AND BE CAREFUL WHEN YOU DO IT BECUSE IN THE INSIDE IT HAS A MIRROR ATTACH TO IT SO BE GENTLE WHEN YOU PUT IT DOWN , ONCE IS DOWN YOU CAN FLIP IT SO YOU CAN CLEAN IT . OK NOW YOU CAN SEE THE WHOLE BACK OF THE T.V. WITH A CLEAN PAPER TOWEL YOU CLEAN IT . THEN PUT IT BACK TOGETHER USE WATER ONLY , GOOD LUCK
