This is Emerson's #1 problem.
The Inverter Transformer on the power supply/backlight inverter board goes bad. It's what powers up the screen for your TV. When the part goes bad, it doesn't have enough juice to power the screen and the TV automatically turns off. You have 5 Inverter Transformer on your board.
You can fix the problem by replacing the whole board or replace the bad Inverter Transformer.
Here's where you can get a new board for a good price:

Check the diodes. One may be shorted. A bit over a dollar on Mouser.com

Why does my 32 inch emerson flatscreen tv Lc320em9 B stay on 3-4 mins then turn off by itself?


Fault with the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Turned itself off, wont turn back on tried unplugging for 30 min. and plugging back in didnt work


The power supply module may have gone out, if you get any indicator light then the 5v standby power supply is working. It can be as bad as the main board is bad. Check the power supply circuit first.

The tv red light keeps


Try leaving it unplugged for an hour so it can reset itself.
If it still has the problem, it may need a new power supply inverter board. That's what happen to mine.
