I have the Samsung model: LN46E550F6FXZA, I can hear it power on, the red light on the front blinks 5 times then goes off. There is no sound or picture.


You will need to have it repaired, looks like the inverter board is broken. Google Samsung tv blinks 5 times, there's tons of threads.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Six (6) blinks on the Timer/Standby led


6 blinks means lamp thermal fuse blowing, replace thermal fuse.

Tv turns self off when turned on


Does it blink a certain amount of blinks pause a second or just blink constantly with no pauses? Let me know it will blink a code if its going into protected shutdown. And it will blink constantly for another reason.
