SOURCE: TV turn on and off
Your TV has a power problem, it maybe high or low supply voltage that causes the TV to turn it self off because of an error. A technician from the manufacturer knows what error it has just by looking at the flashing standby light. Best is to take it to an authorize service center for repair... ^_^

I own the same TV and had the same problem.
It's the #1 plaguing issue with flat panel TV made by Funai corp. Emerson is made by them.
Normally, when this happens, the TV goes into " Protection Mode " because of a failing circuit board.
The most common thing to go out on flat panel TVs is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board. But, I can't say it's 100% the problem because I can'tactually look at the tv over the internet. I can only make guesses with the symptom. I'm willing to bet you have the same problem like mine. One of six Inverter Transformers when bad on my Power/Backlight Inverter Supply Board. I replaced it and it works fine again.
You have a few choices:
1. You can try leaving the TV unplugged for 30 minutes so the TV can reset itself.
2. If by chance the TV is still under warranty, go that route.
3. If you have some electronic experience, if you can find and purchase a Service Manual at Tvtechcenter.com; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $6. And most cases the new part cost less than $15. The service manual at the site is under LC320EM82S.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
I hope I shed some light on the subject for you.

I think you are looking at a power board problem. I had the same thing happen to a Vizio and I replaced the power board and it solved the problem. It could also be the input board but most likely the power board.

I have just fixed my own LG 26lc55 flatscreen.. with the problem of the red light is on and when i turned on the tv, nothing happened not even back to the redlight..
Solution-- take off the back panel, in the middle there is a brown " plate " with a lot of electronics, one of the black capacitor is burned out. if you look closely at the top you will see one of them is broken " the + on top is open " in my case " maybe all ", it was a 3300 uf, 105 degree, 10 volt capacitor, i took it of bought a newe one at a electronic store " 3 $ " and put it in. took 10 minutes and my tv is now working.. BY THE WAY, i could not find the exact capacitor, so i bought a 3300uf, 105 degree, but 16 volt. and it works like a charm.. REALLY HOPES THIS WILL HELP YOU..!!

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.
