Most likely cause is bad filters on the main board. This is common problem and will require the main board to be replaced.

if you don't hear a click its the power over switch. on the power board it is a black box. if you have the back off turn the tv on and then out of stand by and flick the black box it will probably turn on.

Is the red light suppose to stay on when you turn off the tv with the remote?


Yes it is supposed to stay on. This is the standby light. The television still draws power as do many electronic devices when not turned on and when in standby. If you do not want the red light to stay on you will have to unplug the television.

most LG have a "vacation switch" on the bottom right hand side of the set very near that standby light.

it is placed poorly, where you can accidently click when grabbing the TV to move it or swivel it.

it is a toggle switch, a "master power" switch.

you may have bumped it to the off position. flip the switch, your standby light will come back on.

Same problem: LA40R71B


Does it make the the samsung jingle when it trys to turn on? if it does you need a power supply if not then most likely it is the main board. I would contact you r local service center for help and if the standby lights in the front blink in a certain pattern write that down it is a error code that the technicain can use to solve the problem.
