I WROTE IN A WEEK OR SO AGO ABOUT MY SAMSUNG PN51F8500 BLINK TWICE,FIVE TIMES,YOU ASKED ME TO PROVIDE MORE INFO. ALL IT DOES BLINK TWICE,FIVE TIMES NO BACKLIGHTS,SOUND,NOTHING! I WENT OUT AND BOUGHT A NEW POWER AND MAINBOARD FOR IT SAME RESULTS. LAST NIGHT I DID SOME VOLTAGE TESTING I CHECKED ALL VOLTAGES EVERY VOLTAGE WAS THERE BUT THE POWER TO THE XMAIN THE Vs WAS SHOWING AT 4.0 BUT NO Va VOLTAGE?
KALVIN MOSLEY … with a new power supply and a new main board, the most likely culprit are your leds. to test, unplug your connector leading to the main board from the power supply. the backlights should come on and stay on. if they do not, troubleshoot the leds. post back with your findings for any additional assitance.
