As suggested in another post, w2power has provided this solution. It is the only thing that has worked for me thus far. While it is a pain, I can at least consistently get my set to turn-on when using this USB cable method with logged-in PC attached to Olevia's service port (I have the 23" version)
"I think this model has a timer on it, it seems to go when the warranty runs out, not proven but Mine went out about a month ago. My only fix is to plug my tv (via the service port which is COVERED) to the usb port on my computer using my BlackBerry usb cable, in other words the Mini USB. Seemingly I must be logged on to do so and wait for the Chime form my pc, a balloon will pop up for new hardware not recognized (vista) then press the power button and then it turns on, unplug the usb cable and make sure the source is set to tv / video or else it will power back off and you will have to start all over. Theres NOT A PERMANENT fix yet but this is what I do every time I want to use the TV, I have a laptop so I use it as the Monitor just to watch movies. If you have a desktop I recommend keeping the cable handy BUT DO NOT LEAVE THE USB CABLE IN FOR LONG USES. THE SERVICE PORT IS COVERED FOR A REASON!!!

SOURCE: samsung lcd tv power problem
Because the Samsung LNS4051D would not turn on and the power LED would blink 4 times and the relay would click and this would repeat again and again. I replaced power supply board parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors, three had their tops bulged up slightly that I missed on initial visual inspection. After seeing the reports of problems with these caps on http://www.fixya.com/support/t1336881-will_not_turn_or_off , I replaced them with Radio Shack part 272-1032, 1000 uf, 35v. They are slightly bigger, but fit OK. TV is working fine now. Cost was 4 x $1.59 = $6.36 plus the time. I saved between $100 to 300 in the process of either replacing the board or getting the unit serviced.

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.
