TV stopped working, fuse blown?
I have this spectra 32" led tv from this thread. I decided not to use it in our trailer and instead put it in our den 2.5 years ago when we purchased it. It gets very little use. http://www.rv.net/fo...

I would not simply clip another fuse to this one for "testing", the proper way to test a fuse like this is by using the Ohm setting on a meter.
You need to make sure the TV is unplugged and set your voltmeter to Ohms. Then place one lead on one side of the fuse and the other on the other side.
Meter should show 1 or 2 ohms or less depending on the accuracy of the meter.
If you get no reading at all then the fuse is blown and needs replaced.
Just checked and the meter shows 2-3 ohms across the fuse.
Fuse is good, most meters do not do a good job of zeroing out at this low of resistance. Chances are if you put your meter leads together it will measure the same 2-3 ohms.
The bad news is something else in your power supply has bought the farm...
Check for any electrolytic capacitors (these are round cylinders which have a metal flat top when good) which may have a bulge in the tops (this would indicate blown caps) and sometimes changing those will bring back a dead power supply if the bad caps didn't do other damage on the way out.
The bad caps can be changed but you need low ESR types which you won't find at your local Radio shack..
On edit.. looks like the caps on your power supply are laying down... can't tell by the photos if they have bulged tops..
