It was Diode D611 for me. Was measuring 0.2ohms both ways on the board and 0.0ohms unsoldered.

SOURCE: flat panel tv blows fuses

next to the fuse that blows is 4 large black diodes2.gif.one of those is common to short out. the bad one would give you areading of zero ohms when checked with a meter. or just replace all 4.most likely its location D603. hope this helps

try a diffenrt outlet if it still bunrs of a different fuse! could be the fuse not big enough for the different appliance on the circuit !


i would suggest take it to a tech it could be a problem in the tv that could cost only a few $ to fix !!!!
against trying to much to plug it in and out you could burn transistors or other expensive part of the tv!

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: ba71f0f01042 power board blows fuse

I'm not too familar with this model, but to give you some pointers, you will find when you have this problem the fuse will go straight away as there will be some of the semi-conductors short circuited. Check your bridge rectifier diodes & also the chopper transistor in the power supply. As a general check, test most of the diodes & power transistors & replace any that read short circuit on your meter. Hope this may help you as a guide line.

What would make the fuse blow as soon as u plug it back in " Emerson EWF2705 flat screen tv?


most likely a dead short in the primary of the power supply. fuses go bad for reason must be careful about replacing with out checking to make sure more parts are not broken with only a fuse replacement.

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.

Part number#
Whole board, BA71F0F01042
Mini Transformer, LTZ2PC0MS008

I don't have any power to the t.v. even though it's pluged in to the outlet. It's a emerson model EWL20S5B?


Small TVs like this almost always are made up of two boards inside - a power board and a main TV board.

And almost always there's a fuse on the power board, near where the power cord goes in.

Checking that fuse is the only thing you can do by yourself.

Your next option is to give the TV in for repair to someone who fixes such things. Chances are high the problem is in the power supply board and is repairable.

However, the cost for doing so can be prohibitedly high as cost of the TV itself is prohibitedly low. I mean you may be better off selling it on eBay for $50 and buying a new one.

I know I'd buy it for $50 there.

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.

It being emerson 32" hdtv lcd turns on but immediately turns off


This is Emerson's #1 problem.
The Inverter Transformer on the power supply/backlight inverter board goes bad. It's what powers up the screen for your TV. When the part goes bad, it doesn't have enough juice to power the screen and the TV automatically turns off. You have 5 Inverter Transformer on your board.
You can fix the problem by replacing the whole board or replace the bad Inverter Transformer.
Here's where you can get a new board for a good price:

WHERE To BUY power boards for emerson 32" FS TV


I had the same problem. Mine gave out in 4 months. Those boards are hard to find right now. Google the the board# BA71FOFO1042 and someone like (buyjimmy.com) I think will sell TV parts. If not, you can fix the board itself like I did. Mine was a bad inverter transformer. If you need the parts# for anything let me know, I have the Service Manual for the TV. Good Luck
