Question about Emerson EWL20D6 Television

Emerson tv turns itself off after fifteen minutes

Posted by on

  • flootytooty Feb 04, 2009

    My EWL20D6 just began doing this. A repairman I spoke with over the phone says that it means the TV has a problem somewhere - in other words, something is malfunctioning in the TV and so the TV shuts itself off so the malfunction won't cause any extra damage to other things in the TV. The bottom line is that your TV needs to be serviced, and either it can be fixed or, if an entire circuit board is involved or if a part cannot be replaced, it can't be fixed. I hope this makes sense. Kathleen Richardson

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

My emerson tv try to turn on but goes to stand by


Hello

Unplug the power cord for one minute, then plug the cord back in . This allows the unit to reset itself.

Check the breaker box to make sure that the switch that controls the TV is not switched to "Off." If it is, flip the switch back to the "On" position.

Check the batteries in the remote control if attempting to turn on the TV from the remote. Make sure that the batteries are properly aligned. Try replacing the batteries.

Grab your Emerson TV's remote and hit the "Input" button at the top multiple times. This will cycle through the available video inputs for the Emerson TV.

You may have had the wrong input selected accidentally, such as the one for the DVD player. This will reselect the correct video input for you to enjoy television programming via your cable or satellite receiver.

If, however, your Emerson TV still lacks audio or video, peruse your A/V cable prong-to-port connections and ensure they are correctly made. The A/V cable has one red, one yellow and one white prong on each of its ends, for a total of two of each color.

Appropriately, there are red, white and yellow prongs on the back of your Emerson TV and the back of your cable or satellite box. Make sure the ports and prongs are matched up by color and have not been switched up.

I have a LCD Color TV, but when turn on, green


The most common problem is the Power/Backlight Inverter Board. There are 6 mini transformers on the board, one goes bad and the TV will turn itself OFF automatically for " Protection Mode". Replace the whole board or replace the bad mini transformer.

Whole board, BA71F0F01042

My Emerson EWL20D6 turns itself off after about 6-8 seconds


It's the #1 plaguing issue with Emerson flat panel TV.
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.

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 over the internet; 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 $20. And most cases the new part cost less than $15.

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.

Power turn off after 45 minutes to 1 hour used


Check the "Sleep Timer" settings. If set to 45 minutes then TV would automatically turn itself off 45 minutes from being turned on. The variance in the "on" times is due to the TV turning itself off after not getting a signal from the remote for fifteen minutes.

Good luck,
