I was watching a TV on my 40'' Samsung LE40A556P when suddenly it switched off and wouldn't switch on again. The standby light keeps going on and off at a regular intervals of 2 to 3 seconds and there is a small flash of light on the screen coming from the bottom right hand as if the TV is trying to start up but it keeps cutting out before the picture comes on both the standby and flash of light are in sequence are in sequence. Please Help.

1. Your Tv is in need of service.
It sounds like the tube that give light to the screen for visual is defective and needs replacement.
2. The power supply circuit needs repair. Possibly a capacitor or diode has failed in the start up circuit
