I'm sure you already checked the outlet and the surge protector bar. It's lame how the warranty only last a year on this TV.
If your lucky, it will be just the fuse that need to be replaced. It will look like a little glass tube with metal caps on the ends. Radio Shack or an Electronic supply store will have the fuse. Just show them the fuse and they should match up the type and size. It needs to be 4amps and 125volts fuse.
If this doesn't work, you'll need to replace is the power supply board. The board# is BA71F0F01042. Your power supply board should have the same number on the lower right side of this board.
The board is hard to find right now. Only three places I know of to find it.
Sadly, nobody has them in stock.
I wish I had a extra board to sell you, because I know how to repair the power supply. I have the schematics diagrams and part# for the pieces on the board.
If you ever come across a replacement board, let me know. I would like to buy your old board. Here's my e-mail, firstname.lastname@example.org

Hi, I own the same TV and had the same problem. It's the #1 plaguing issue with flat panel TVs 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 TV 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't actually 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 you have some electronic experience, if you can find and purchase a Service Manual at Tvtechcenter.com: http://www.tvtechcenter.com/xcart/search.php?mode=search&page=1 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.
3. 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 succeeded is using the DirectTV remote control for the Emerson 42" plasma TV, by using a Samsung code. On my TV, was 10060. If this one does not work, there are a bunch of others that might work. Good luck

everything with sound picture av component has to do with the main board of the tv not the power supply the only thing you can do its replace the main board not the power supply board or anything else cause it may be only a resistor or a capacitor but to replace it the guy that comes to do it will charge more than replacing it go to www.shopjimmy.com and check your tv model and it will give you what you need and the price and cheaper than the manufacturer
