Question about Emerson EWL20D6 Television
I'm using a Regal 32" lcd tv as a second monitor for my Toshiba satellite L30 laptop, connected by vga cable. Everything worked great for about 6 weeks. Today, the tv simply turned itself off. I reconnected everyting and it was working again, but the tv shut off after a few minutes. I've gone through this process a few times and am exasperated. Please help!
I'm thinking the Comcast DVR box maybe putting out weird HDMI signals and the TV can't translate it. I would call the Comcast people on this one.
In the meantime, I would try finding another source the uses a HDMI cable to rule out the TV as the problem. Basically, testing the TV to see if the problem still happens when you use something else than the Comcast box. Try a Blueray player, Playstation 3, or Xbox. Just something that uses a HDMI cable.

SOURCE: Tv shuts off after 6-8 seconds
capacitors in the power supply, they all should be replaced, before it takes out the rest of the ps. there are companies that rebuild them if your tech is not up on repairing them.

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.

Just repaired this actual model.
remove the back of the tv. Loof at the circuit board on the left as you face the back of the tv. In the middle there is a diode that burns out. Remove all ov the screws holding this circuit board to the tv. Carefully unplug all of the connections and flip the board over. See that the number on the back side of the board by the burnt diode is d1940. Have the diode replaced by a competent repairman and oberve polarity. put everthing back as you found it and try the tv. You may want to have a fire extiguisher nearby.
