Re: Dropped tv
If the fuse keeps on blowing once you plug it in, a line may have been damaged and checking it will be a little tricky because you will have to trace all the connections that goes in and out of the fuse line.
there is also a possible crack on the board that is why the fuse is blowing up since the fuse gets too much power or the voltage regulator for the whole unit, because of the fall the voltage regulator may have been damaged.

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.
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
You should be seeing a validation that the TV is getting power. Like the lights are coming on, or you are hearing clicking when you plug in or power up the TV. Make sure you have the TV’s power cord plug inserted all the way into the TV. Also, make sure the TV's cord is plugged into a good power outlet.You may want to plug something else into the power outlet to be sure the outlet is good. I don’t see how laying down the TV would cause this issue.Unless the TV was kind of dropped and or twisted to cause a board inside the TV to fracture/break. I hope this information has helped you. Good Luck.
This will sound strange, but some DVD players and cable boxes have separate volume controls. I would check the settings for both of those to make sure that the volume has not been turned down and also check the connections from the dvd player and cable box to the tv. Make sure all connections are solid.
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!
