Most TV's use a switchmode power supply, you can hear it when the tv "clicks" as it turns on from the remote.
Over time, these can suffer from dry solder joints, among other problems, due to the power supply heating and cooling constantly when the TV is on and off.
One thing you can try, as a test, is to blow a hair dryer into the air vent on the TV for a few minutes, and then see if it turns on more reliably, as usually heating the power supply fixes the problem in the short term. This would also be evidenced if the TV will usually turn on just after turning it off, but leaving it off for an hour or two results in the problem coming back.
Unfortunately these days it's cheaper to get a new TV with all the new tech standards, than have the old TV fixed just for something else to go wrong in another year or two.

TV doens'nt start

Take to repair shop, must have a loose connection. I am an electronic Tech, 20 years experience. When you turn on a late model TV they do a self test and if they detect a problem then they shut down. I'm not really up on LG, I work for Panasonic and our LED's flash, and depending upon number of flashes it tells you where the problem is. I would suggest phoning LG for the address near you of their Authorized Service Agent. Get the guys who fix them everyday to do the job.
