The pixels on your screen are controlled by a matrix composed of switches that turn off and on to produce light.
They are located vertically and horizontally, row-wise and must function together to produce everything from black (everything turned on so no light, or very little, can escape) to layers that represent the three colors that are used alone or in combination to produce the millions of possible shades of each.
One of the switches that controls one of the vertical columns has failed and has turned on the entire column that allows red to display.
The problem switch (a semiconductor combined with many) is permanently turned on, probably part of the screen assembly itself, and was placed with others by robots.
The pin spacing on these 'chips' is very small and often makes the assembly unrepairable.
While LCD panels have fallen hugely in price, you may be looking at a parts cost (labor is probably not too bad) that may make you decide to replace the set.
Unfortunately, the once-proud Emerson name has sadly been degraded and there is a lot of their electronics available from companies that specialize in 'refurbished' products, an indication that they have a large failure rate.

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.

Mine stayed in stanby mode and all I had to do was to switch the plug to a different outlet. The power strip it was on wasn't providing enough power. It worked fine for a month before I had a problem.

I found a way around this problem. When this happens, don't use the remote.
Walk up to the TV, then HOLD DOWN the power button and while the lights are flashing, start pushing the menu button on the TV at the SAME TIME.
Then your screen will turn on. No idea why this works. Just stumbled on it while getting ********** that this TV, I had less than a month, suddely would not come on anymore. I was about to unplug the whole thing to take back to WalMart and just started pushing button combinations and found this worked.
