Hi
its not big problem but not a simple solution for this problem. this can be software issues. you call your lg customer care services and share problem.

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. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

is not possibily,to any ac.the timer run just for 24 hours.on the power surce of your ac you can make a timer control programms, who take or give energy to your ac inverter(you put the ac inverter to run , and when the energy is shut down ,the ac inverter is stop working and when the energy is come back the inverter start working)

I have same tv same problem.....any luck?

This is possibly either a complete outdoor pc board error or an E-Prom error on the indoor pc board. You can try shutting down supply power completely for a minute and then switch on. These units also have a delay timer system which does not like to be switched on, off repeatedly in a short period. Please also check for reset button on the outdoor pc board. Hope this helps.

Hi...there,
Well, what you can do it replaced a new backlight inverter or you can repaired it. Cuz your old inverter are busted. Have a nice day!

The backlight inverter board is defective or a high voltage cable going from the inverter output to the lamps is damaged or touching ground.
