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.

SOURCE: I have an emerson flat screen that will not turn on ? The red stand by light comes on, but when you hit the power button the green light comes on then shuts off quickly and the TV will not come on?? A
Try leaving the TV unplugged for 30 mins so the TV can reset itself.
If that doesn't work, most cases with the Emerson TV, the Inverter Transformer goes bad on the backlight Inverter Board. It's what powers the screen for your TV. If it can't power up the screen, it automatically shuts off. Basically, they call this "Protection Mode" with this happens.
You can get a replacement backlight inverter board at this web site link:
Just make sure the board number matches your board.
If it fixes the problem and you decide to throw your old board in the trash, I would like to keep the damaged board if possible. I want to do some research on the board to find out what really causes the transformers to go bad. Here's my e-mail email@example.com

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.
