Popping sound from TV

Yes the caps on theower supply, but you can check power supply board by smell an look for burnt parts it is common. May need more than one board if they are cheap get both.

the loud pop was a capacitor or a resistor popping, it will need replacing.

Popping noises are not a good sign; I suspect the sound came from the catastrophic death of an electrolytic capacitor or worse, the death a a power semiconductor.
Open the lower cabinet and using a good light, look for a smaller, separate board with fairly large parts on it; some cylindrical in shape, others block-like that may have copper wire showing.
If, as common, this board is plugged with connectors into other parts of the system, you may be able to swap the failed board out for a replacement bought from a Mitsubishi service center.Expect to pay $100-$150 US if the set is no longer under warranty.

Your set has a problem with its power supply. If it is under warranty, have it replaced ASAP. If your warranty has expired, you can take the set to any good repair shop - ask for an estimate before having any work done to it.

Hello,

The problem is that there is a bad capacitor inside the unit, it is either on the main panel or the power panel. The popping sound you got was due to the fact that the lead on the capacitor was bridging, therefore causing some electrical popping sound.

Run a check on the main panel and the power panel for any bad capacitor and replace it with a new one. That way, your television will be in good condition once again.

Take care and good luck

Power supply board is dead.The board where the power a/c cord plug into it.Replace the power supply board.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Haven't fixed it yet. Going to find a electronics repair shop locally and have them repair it.
Thanks.

It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.

Any other symptoms? You may be just hearing the occasional sound of static being bled off, or, if the set is not working properly, the sound of the high voltage section trying to compensate...accordianman

Could be a possible flyback. yes.. for a 27inch i would not think it would be worth it... 27 inch tvs are realativly cheap.. the lowest price to repair would be about 200 if you got lucky.
