There is some short circuit inside any one of the circuit boards. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact any experienced service technician, or the nearest service center.

The above link goes to lg's website describing the red flashing light where the power switch is, and

another switch down below which can turn that light off.

Try switching that other switch below off so the light turns off. Then, switch it back on.

If that doesn't work, then service should be scheduled for this discontinued model.

Hope this helps on your lg tv.

a very low battery could cause this recharge the battery and look in the menuw to see what you have it set on,,, ie power saving?

check your led on the remote

This is due to switches malfuction due to corrosion in switch and dust accumulated in the switch. Since you rarely used switch now after failure of remote of remote control you tried to operate the switch. Another thing you said did"t get picture, maybe memory problem is there. This can be sorted out by the technician only.

It sounds like you have problem with the switch on the tv itself. try opening the front panel where switch is located and check wiring or maybe change the switch which you can get it online.
