Tv popped and a smell came from it. Iv'e checked the fuses and they are good . I checked all the components and there is no visible burned componets. the only thig i found was a uncoated disc capacitor that had 1 leg disconnected and I soldered that back on.(number on circuit board is thx3415).I guess it is part of the degausser.

Re: TV wont power on
Device is a thermistor (thermal resistor) thermistor and a vatistor control the on time of the degausser Sams Photofacts has the schematic for the set have to match the suffix Some public Libraries stock photofact schematics you may be able to go to al local library and get the part number or the specs as to whether it is ptc or ntc etc to get a match or online here

The power outage probably popped an inside fuse or damaged some electronic components. If you are capable, unplug the tv and place it face down on a soft towel. Unscrew all the screws on the rear that hold the two halves together. Lift the back panel slowly making sure all is free. Look for the fuses and check if they are blown. If they are, replace them with the same rated fuses. This is the cheapest fix. If the fuses pop again after this, then something beyond the fuse was damaged. You will need a repair shop to troubleshoot it. Once fixed, plug the tv into a surge protector for future use. Hope this helps.
Having similar problem and it sounds like an obvious short circuit if you heard it and can smell it, and it probably took out power supply fuse, so the first thing to do is pull off back of TV and look for obvious toasted components by eye or smell. Capacitors sometimes will pop when they go, and you can see the tops will be bulging out, or black marks, so look and smell all large capacitors first on power supply main board, then check to see if fuse blew. Sometimes the obvious is easy to fix.
Check the main power supply regulator section for faulty component/s. The sound you heard might be of a bursted electrolytic capacitor at the power regulation stage circuit, due to some spikes in the input AC voltage. Open the TV and check this section. Be sure to unplug the TV from AC mains wall socket, before open it.
There is a fuse on the power supply close to where the A/C is connected to the board.If the fuse is blown, look at the board and see if there are any burned components and or swollen capacitors. If there are bad components, I would suggest getting a new board. If the board looks OK, disconnect the connectors from the board but leave in the A/C connector (this way you can isolate the power supply board), replace the fuse, and power up the TV. If the fuse pops after the power is applied to the unit, then the power supply is bad. If the fuse is still good, then power off the TV, connect on the main board’s connections, and power up the TV. If the fuse is still good, then power off the TV, connect the inverters, and power up the TV. If the fuse blows now, then the inverters and or the panel are bad. A working power supply will create 5vdc for the main board’s stand by source voltage.This can be found on the power supply at the main board’s connector and it is labeled in black text. I hope this information helps you. Good Luck.
Well that pop had something to do with the power components inside the TV frying. I would have to say there is nothing you can do to repair it as its dangerous to work on such things. I wouln't waste my time bringing it to a repair shop they will probably tell you to just buy a new one.
A popping sound can be a good thing because it will be easy to identify a blown up or degraded component,if you are familiar with tv service you might spot the bad part fast just by looking at it and then change it,sometimes you actually have to check a component with a meter to tell is gone bad,check the main fuse ,it should be close to were the power cord comes in,if is black you will have bad components ahead and you will need the assistance of a servicer,if you are not too familiar be safe and call for help.Let Us know how it goes.
If you're NOT still under warrantee you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace.
Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs.
You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the TV to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet.
In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer.
All can be replaced at a local electronic or hardware store and they're easy to replace
If this does not correct the problem, you may need to have your TV serviced.
