My lg 32lc2du tv will not come on green led light comes on and blinks for a bit and stays on but no pictures


It sounds as if either the supply to the LED panel is faulty or an open circuit to the supply. What input do you have on the unit? DVD/CABLE?

LG 32LM3400 turns on and light flashes three time but no picture


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

Your problem is most likely a fried circuit board. I always connect my good electronic to a back up battery. but your problem might have been storm or surge related, I would take it to a repair center and get an estimate.
