if you have replaced the fuse already then you know how to open the back of the set . The problem is more than likely one of the diodes in the rectifer circuit . They will be the four large black components The bad one will have to be desoldered and a new one soldered in its place . It will take a small amount of technicial ability but can be done easily at home.

SOURCE: Emerson EWL20D6 TV turns on and the picture goes right back off

Mine is doing the same thing. I talked with a local repair guy over the phone and he says that (obviously) something is malfunctioning in the TV and a sensor shuts it off to minimize the damage to other components. This would be ok if the TV were 20 years old (they used to last that long); however, mine is only 1 1/2 years old and Emerson couldn't give a damn that the TV is a piece of ****. Silly Mimi

SOURCE: 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.

Had a blown fuse on main board 125V 4A replaced and indicator came on green light flahes twice and goes off


Something else went when the fuse blew---voltage checks are needed and someone needs to check for shorts on the set to ground.

Watching the TV and heard a "pop", it went dead. Opened up the back and found a blown 4A 125V fuse. Replaced fuse and plugged in TV. Fuse blew instantly when I plugged in the TV. Sylvania...


The power suply unit may be dead......if the fuse blows instantly it means that the main input is short.
possible parts damaged :the diodes from the mains, the power tranzistor and the ic from the primary part and other components around them.
First unplug the tv, unload the mains capacitor (using a light bulb) check all the diodes from the rectifing bridge, check for any shortened semiconductors or blow resistors.


BE VERRY CAREFUL !!! THERE IS A RISK OF ELECTRIC SHOCK ,IF U DON"T KONW ANY ELECTRONICS TAKE IT TO A SPECIALIST

I have a Brother HL2140. It was plugged into a 220v outlet, is there a fuse that can be replaced?


hi. I had the same problem and to fix it you need to take printers right-side cover off. Underneath you'll find a Power Supply Board - hidden under metal cover. Take it out and disconnect two cables from it. Now, I had to replace an fuse 125V 4A and varistor E241AD 83P on the Power Supply Board in mine HL-2140. It works fine now.

Note: I could not find the exact replacements in electronic store so I used:

- fuse: 250V 4A

- varistor: FNR 10K241 (241 is the important number)


Hope it helps.

125v Fuse Blown Possiblities? and alternative replacements?


Well, fuses are made to protect systems from shorts and surges, so it might be okay even if that was the problem. I'd closely reexamine the area you soldered-- checking to see if you globed any solder over circuit pathways.
Then you could try a new fuse.
Another option would be to DEsolder it as much as possible, maybe even remove the coax port, before you replace the fuse. If it works after that, then that would be a good indicator that the fuse blowing is related to the coaxial.
If I've learned one thing over the years, it's that when separate symptoms occur at around the same time, chances are they have a common cause.

The tv keeps blowing fuses


Hi your problem is that a component(s) inside your TV has probably short circuited to Earth, this then causes a massive current to flow and this blows the fuse. Due to the types of Component failure from this, this TV should go to a reputable repair shop. Get a firm "Quote" and an explanation of what needs to be done.
