Loud pop from surge protector that results in intermittent sound on Samsung 46" tv

Yep, power spikes kill. Power spikes kill all. Power spikes kill all forever. Replace all and get a new surge protector that costs at least $99. If you never need it it is called insurance. I am in FL the capitol of lightning. High priced surge protectors are cheeeeep when lightning is there.

Has there been a power surge through the mains? That may have caused the issue and ruined your TV. I am not sure if the TV can be fixed if this is the case.
To prevent this happening again, plug any TVs, expensive desktops etc into a surge protector. This will prevent any power surges from the mains overloading and ruining your devices.

I hope this helps.

Hello.
You probably did not have that tv plugged into a surge protector. When the power was restored, a surge came through the line. A power surge is a spike in voltage above the maximum a tv, appliance etc. can handle of 169 volts. They are very brief, usually lasting millinths of a second. Power surges can vary in duration and magnitude, varying from a few hundred volts to several thousand volts.

That said, now what do you do. If the tv is under 3 years old I recommend that you take it into a local TV repair shop for a free estimate of repair. If it is older than that, I would not repair, just replace. J.

Well if it is DLP TV then crack/ pop sound was broken lamp in TV and if its another kind of TV as you did not mention its model and brand then have to check accordingly.

Well, the power supply may be still damaged by the surge, what may happen is that when first surge happens the surge protector protect your TV by sacrifing itself but then the second surge comes along, since the protector already blown up then the surge will just come right through to the TV on the second surge. That is bad problem for the surge protector that sacrify itself but can only do it for ONE time.

This sound like the power supply board went bad. You should check that. See if the fuse on the board is blown first.. You can get a "pulled" power supply board on the net if needed.

Surge Protectors are devices that usually you plug your equipment to.. and it protects it from Voltage Spikes that would otherwise destroy the device without it.. saddly not all Surge Protectors are the sam.. some are completely useless..

If you are really serious about protecting your PC not just the hardware but also the data and your work.. might as well invest on a UPS(Uninterrupted Power Supply) unit.. it has everything a surge protector can offer and more..

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

You have a short in the power supply. Look at the regulator and or rectifier diodes. These are all on th primary side of the SMPS (switched mode power supply) the secondary side if shorted shouldn't cause a blown fuse at all.
