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.

Our HP5060N/ HP PL4260N Plasma HDTV made a loud pop sound and then we lost the picture - still have sound. My son was playing Playstation at the time. Any idea what the cause is? Is it worth the cost of...


Hi, I have just experienced the exact same loud pop sound. Then no picture or sound. Just died. Spoke with a rep at HP and was told that this (having owned for 4 years) is out of warranty and the "main board" has died. It will cost $629.00 plus tax to repair. This would provide a 90 day warranty on those parts replaced. It's about the same to buy a new tv! So I am throwing this JUNK away and will never buy HP again. Best of luck to you all!

TV LG Model 50PX1D-UC Flat Panel Television Loud Popping Noise. TV goes out. I turned on my tv the other morning and it let out a loud popping noise and the picture went out. Any suggestions...


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

LG 50inch Plasma received loud sound then went black


I suggest you guys take your TV's into a repair shop like Sears or Best Buy... The main reason most plasmas go dark is because of decay, but I don't think this is the case. Because what you describe is similar to what happens in LCD's when their back light goes out. Although you can open up and repair the back light your self in a LCD, I would not advise you to do so for a Plasma, because of the hazardous chemicals used in the plasma display plus the fact that plasmas don't use back lighting. And 2 years is way to soon for decay to be a factor. So more than likely a circuit shorted out and the TV has to be opened up to be repaired.

LG plasma tv made loud popping noise


The plasma gas tubes may be damaged or the gas couldve leak out. remember plasma have to remain upright at all times even when transporting them, if they are not you should just set it up straight for about 3-4 hours before turning it on.
