KDL 46 HX 823 STANDBY 4 FLASHES MESSAGE

(1/1)

buggsy:
 HI GUYS ANYONE WORKED ON A KDL 46 HX 823 46" SET

POWER UP STANDBY 4 FLASHES.....THIS MESSAGEW INDICATES BACK LIGHT PROBLEMS BUT DO NOT KNOW IF APPLYS TOT HIS ONE.

OVER COMPLICATED AS USUAL   MAIN POWER BOARD, INVERTER CONNECTED TO LDVS

downunder:
The HX823 is edge lit by LEDs. Code 4 is indeed a backlight problem. A test of backlights is to remove the LVDS cable, then hold the Power button on the TV as you plug it into the mains. You should get 2 seconds of backlight, then they go off. Can be repeated ad nauseum . May give you a chance to spot any bad LED strip.
