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.

Screen is black and power indicator light blinks steadily


Samsung TV's seem to be notorious for this. This generally means that there is a fault somewhere on the main boards and the components are shorting out.
Unfortunately, it's not economically feasible to repair flat panel tv's. It can be done by an expert repairman, but the cot of the new tv isn't far from what the repair cost will be.
