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. good luck!

go to the nearest PC repair shop..your board/processor burned out.
or if you have still a warranty for the laptop better contact the supplier were you bought it and as for a replacement.

The loud pop you heard was a filter capacitor. The problem now is the power supply is shot, or should I say the capacitor that is connected to that voltage output is blown. You will have to replace it with a new one. I would suggest just for your curiosity, unplug the TV, take the lower panel off (you will need a star head driver to do this) and look at the power supply board (the board on you left side) look towards the middle of the board and you will see a heat sink in the middle of that heat sink you should see a capacitor (or the remains of one). its value is 2200uf 16V (I believe that this is the one that has gone bad), you should also look for others that may have blown also. I would also suggest that you have a qualified TV repair person come to your place and work on this for you, due to the nature of this section of your TV.
If you choose to do this yourself you will find this useful. Get a schematic to find the values the Chassis number I believe is ITC222. Here is a link to the schematic:
I hope this helps,

The first and most likely cause is that your lamp has blown. Simply remove it and inspect when they have blown its really easy to tell. Remove lamp door with a philips screw driver. The door is located I believe on the back of the set towards the right side. Once the lamp door is off there will be 1 maybe 2 screws holding the lamp assembly itself in place. Remove those then the housing should slide right out. The lamp number is 915B403001 for that model.. Good Luck!!!
