If a fuse should blow up, there should be a reason for it. If you replace the fuse without rectifying the problem and switch it ON, the newly replaced fuse too will blow up. Before replacing an other fuse, find out the reason and rectify it. There should be some shorted component/s at its main power supply board. Check and replace them. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ It has schematic diagram of power supply section to many televisions. Pull up older posts by its left side bar. Problems to Sylvania too will be there.

You have a short in the power supply. The power supply will need replacement. You can get a replacement power supply board from www.tvrepairworld.com

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

More likely to be either shorted out bridge rectifier or MOSFET in the primary circuits of the power supply. You need to Ohm out those parts.

next to the fuse that blows is 4 large black diodes.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

first check if there was no short cicuit inside or any wire or parts that have contact and can cause also a grounded and make your fuse always blown...

let me know

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.

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!

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!
