Question about Emerson EWF2704 TV

2 Answers

Looking for schematics or repair manual (TV)Emerson/EWF 2704 27" Flat Screen

My TV isn't coming on although you can hear it trying to. I'm guessing the problem is in the power supply because the shutdown circuitry is turning off the television. Can't find the scematics anywhere. Any advice?

    No luck. Thanks anyways. I did find a blown resistor in the power supply circuit (fusible resistor?). I'll try to locate one and hopefully that does it.

My Emerson TV will not come on..red light comes on but green and TV will not..what can this be?


To attempt repairs you will need the appropriate test equipment, schematic diagrams and adequate experience to perform troubleshooting procedures. It is very unlikely that you will be able to locate the problem by visual inspection alone.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/dave_fb2c45146b845cea

Tv wont come on


All flat screen TV's have a reset button. Most manufacturers leave this out of their manuals so they can give TV repair companies more business, also this button WILL NOT be marked (reset). Its usually on the left side (left side as if you was watching TV). But different manufacturers put this very tiny but most important button in different places just look for it!! :)

My flat screen tv does not have a picture or sound. The stand by red button is on once we press the power button the picture will come on with a message that reads digital television for about a second or...


I've had the same problem with a 32" model LC320EM82S. All the Emerson TV ( no matter what size ) are having the same issue.
I'm sure with your TV, the green light is blinking before the TV automatically turns OFF. Basically, the TV is trying to power up the screen and has failed. Protection mode turns the TV OFF to prevent other parts from being damaged inside.
My solution for fixing my TV was replacing one bad inverter transformer of six on the Backlight Inverter/Power Board. Here is what my board looks like: 767c946.jpg
You can see the six inverter transformer on the bottom of the board. It's what supplies power to the screen. Your board may look similar. You can sometimes find a whole replacement board over the internet for a good price. Shopjimmy.com is a good place to start. Just start searching by your TV model number.
If you have some electronic experience, you can repair the board itself by finding a Service Manual over the internet for less than $20. It will have all the part numbers, schematics, and diagrams you need. I would investigate the inverter transformer for your problem.
I hope I helped you out with your problem.

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 light comes on then goes off and no power


Hi, 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 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 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.
