Question about Televison & Video
Plugged into wrong power adapter and blew up a capacitor and the protection fuse. Need to know the value of the capacitor and fuse.
Both the Capacitor and fuse will have there rating right on them.
If you don't know that you might want to take it to a professional for repair, as soldering them in can be very tricky.

I have the same problem. TV was JUST out of warranty. Sceptre part number is X37SV-Naga and the cost - $285.00 plus $20 shipping. Non-refundable, no returnable.
The TV is of course going to de-solder the board within a year again, so either a good heat sing on both thermistors is in order OR a law suit against Sceptre is in order for putting us a risk of fire.

hi there, i recommend replacing the entire board. once you have a short like this, the micro board itself will become useless. the thin micro circuitry has become separated within the layers, preventing a closed current transfer. its best to order a new canvas so to speak.

Very carefully as we discussed in our expert forums this takes skill and it takes the right equipment as you can burn the thrid layer board and you will be without a TV. First you need a 40 watt iron, 60/40 rson core solder/you need wicking wire/ heat sink and a whole lot of experience. check this website www.badcaps.com even know he works on motherboards for computers this guy gives you tips I would follow them and heed to them if I where you!! Good luck with your repair!

If its after a lightning storm, it really could be anything. Your mainboard could quite possibly be shot. In fact almost anything in the TV could be damaged by a big surge. It could even be that your backlights went out from the surge too.
Does your power LED come on? What is it connected to? Directly to the power board or is it connected to the mainboard? If you have current through all the circuit boards, you may have a burnt tuner or chip on the mainboard.
Might not be worth fixing depending on the size/model. If its a big LCD, you could probably get a good deal on a working one of the same size with a broken LCD panel (~$100). Then you can just replace the broken LCD panel with yours and you have a fixed TV.
