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.

If not under warranty, here's what you need to replace inside your TV. Power supply board BA71F0F01042.
The board is hard to find right now. Only three places I know of to find it.
Right now, only Discount-Merchant has one in stock. Here's the link:
Discount-Merchant.com - Projection LCD / DLP TV Lamps - Plasma ...
I know it would be cheaper to fix the TV, than replace it.
If you end up throwing the old board in the trash, I would like to keep it if possible. Here's my e-mail, firstname.lastname@example.org

This TV is using a power supply MLT168A that has defective capacitors. Replacing the capacitors might fix it, but in some cases the failure is more then capacitors.
Write to email@example.com if you required further assistance.
