It sounds that the main filter capacitor has bursted out due to over line voltage. Check and replace the main power regulator board. If you wish to get more details, check this site linked below.

Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:

SOURCE: LG 47LC7DF LCD TV turns off with a pop then turns back on.

Sounds like a overheating issue. Try facing a large fan blowing across the back of the unit and see if this changes anything. If it does, it might help to blow the back out with compressed air as dust might be helping it overheat.

Its very likely that you need to have LG perform a sodtware upgrade on your unit. Contact LG and see if your tv is one of the applicable units with software upgrade issues, please let me know if it works. Good Luck.

SOURCE: tv made loud popping noise when turned on now

The problem is with the voltage capacitors and transformers on power circuit board.Some of them has burnt off and so only you are having this smell and popping sound.You have to take voltage readings and test power supply components such as bridge rectifiers and capacitors. If there is no voltage rating you need to replace that part if not you have to check the soldering joints and solder it again.

Watching TV and all of a sudden a loud pop came from the back of the set. Doesn't turn back on after unplugging.


Hello
Check its power supply regulator board. The pop sound you heard may be due to an explosion to any electrolytic capcitors on it. If the line voltage exceeds, this fault will happen. just repalce the damaged component. It is best to replace this board as card basis.

Tv went out after loud pop and has clicking noise does not turn on


If you have a Sony DLP, then the loud pop you heard is your lamp.  The lamps last approx. 4K-6K viewing hours.  Read your manual for replacement part number to reorder and very simple to replace yourself.
