Check and replace the damaged component/s at its main power supply regulator section circuit. The sound you heard might be due to a busted capacitor. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

Sounds like a main board fault. Contact any service technician to confirm. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. http://electronicshelponline.blogspot.com/
Power supply...The vacuum sound you heard was a capacitor failing. A capacitor stores energy for later use. For example, you turn on your TV, seconds later you hear a "Woosh" and the picture comes up. This is your tv's capacitor discharging. It's a simple fix if you know electronics though I wouldnt recommend repairing this yourself. There are several capacitors inside your TV. Though not fatal, they can give you a jolt. Call a repair man. I hope this helps : )
The pop noise could be a capacitor poping its top up.This is a common problem to most TV sets today. Usually located at the power supply board.Once this parts give up it usually shorts the circuit and blows a fuse.Replacements of these parts mentioned will often remedy the problem.Flashing power indicators indicate a problem.If you have the chance of counting how many the blinks are I could have told you the problems code are and the source of the problem.
you need to call a repair tech and have them check for blown capacitors in the power supply and the x & y sus (the circuits that light up your screen) for defective capacitors. they are very obvious to see-normally the top a a capacitor is flat, but in this case if bad they will be bowed out -rounded on the top.
most times then not it's the capacitors on your power board that blew there for not supplying the tv with enough power if you open it up and check the capacitors it should be leaking some kind of liquid or the tops have bubbled up. its an easy fix cost>>2 dollars each
Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.
Most likly the Horizontal output transistor has shorted out because of
cold solder connections on the flyback transformer, and or a bad
capacitor in the sweep power supply and or, a bad flyback transformer.
If the set Did not blow the fuse, then mopst likly you will have
a problem in the main power supply where several parts in a kit form
has and should be replaced all together.
