If the 4Amps fuse should bow up, there should be a short circuit in the circuit after it. Check all the rectifier diodes for short. If a stalk rectifier is used, check it. Check the veristor [over-voltage protector; connected across AC input] after the switch for short. The schematic is in PDF, and cannot upload to you by this window. If you wish to get some details, check the site linked here. It has power supply section circuit to many brand TVs. Search the site, with the switching control IC. It will make search easy.

SOURCE: Emerson flat screen tv with red stripe

The pixels on your screen are controlled by a matrix composed of switches that turn off and on to produce light.

They are located vertically and horizontally, row-wise and must function together to produce everything from black (everything turned on so no light, or very little, can escape) to layers that represent the three colors that are used alone or in combination to produce the millions of possible shades of each.

One of the switches that controls one of the vertical columns has failed and has turned on the entire column that allows red to display.

The problem switch (a semiconductor combined with many) is permanently turned on, probably part of the screen assembly itself, and was placed with others by robots.
The pin spacing on these 'chips' is very small and often makes the assembly unrepairable.

While LCD panels have fallen hugely in price, you may be looking at a parts cost (labor is probably not too bad) that may make you decide to replace the set.

Unfortunately, the once-proud Emerson name has sadly been degraded and there is a lot of their electronics available from companies that specialize in 'refurbished' products, an indication that they have a large failure rate.

Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:

SOURCE: 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

SOURCE: Sylvania 6632 LG blows fuse when plugged in

I too had this problem. I read some posts on this site about how to repair it, and low behold, they worked! I took the back off of the TV, and the first thing I found was the fuse was blown. With my meter, I checked the first 1N5406 rectifier diode after the fuse, and found that it had shorted out. Then I had to learn to desolder the diode, which I learned about on Youtube. I bought a pair replacement diodes at Radioshack for $1.49 and four replacement 125 volt 4 amp fuses. The whole repair cost about $5.00 and a few hours about learning about electronics. The TV works great! Good times!

SOURCE: LG 42PX4MVH PLASMA TV - Sound but no picture.

I have the same issue with my LG 42PC3DVA and I narrowed it down to the Y SUS board. After a little research there are a few items that are prone to go. The ceramic fuses (as you found), sometimes the capacitors on the Y SUS, Z SUS, and power supply go along with them You can tell because thy will be bulged at the top instead of flat. I replaced a few of my capacitors - they are only $0.89 each so it was MUCH cheaper than a board.

The other thing that is common on the Y SUS in particular are the FETs (also called MOSFET). They can be replaced if you are good with a soldering gun but they are static sensitive so be grounded. They are also a bit tricky to test so you may want to do some research on how to determine if this is the issue... or you can just replace the whole board.

My Emerson LE320EM3 tv wont turn on, it has not flashing lights and only makes a high pitched frequency when plugged in.


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Tv won't turn on after power surge. Any way to reset a fuse?


Sometimes a power surge will blowout a part inside the tv. If your lucky it could be a fuse which sometimes needs to be soldered to remove and replace. A little experience is required there. A lot of power surges will take out can capacitors on the power board. Some times the board can be replaced or possibly replace some blown caps. Definitely need a TV tech to look at that.

We had a power surge and now my 26 inch flat screen tv emerson wont turn on.... please help !!


When a fuse blows it only means one thing. The power supply board had developed a fault. -it could be due to many factors as the whole circuit board for power is in one package - or PSU board as they are known and any one of the components can fail.. Of course as you mentioned of a power surge- the damage of an abundant or over supply can trigger the input IC ( 110 to 230 variable voltage) to fail. Changing that may not solve the problem altogether as they are other diodes and rectifiers associated with it. Most people or repair men merely swap the whole board due to lack of testing facilities and normally send the defective board to the supplier who will have all the test bench components wired up at his workshop to perform a component check /replacement. Like in your case it might just be logical to get hold of another power supply board ( either new or re-conditioned) and fix it up and enjoy watching tv rather than waste a lot of time trying to identify the exact component failure on your LCD tv. But of course if you are really keen to do your own repairs then look at components just next to the fuse holder and attempt to test individual components and replace same if faulty. Hope u succeed as at times basic components replacement works.

I would suggest replacing the board itself, chances are what caused those fuses to blow is still faulty. did you check those fuses again after you powered it back up?
