Their was a blackout in my neighborhood. The next day in the morning i tried to turn on my 50inch HP Plasma and it made a loud popping sound. The volume on the tv still works.

check capacitors related with the audio output section.

well the only thing is wrong is it was proably up to loud & the loud pop was the speaker bustted

plama tvs do this often after you have it for a while. there is no salution but to buy a new tv. this happened to my dad's friend and he said you cant fix it you just have to buy a new one. he akso said his next tv wont be a plasma of ant type!

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!

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

Get it to a hands-on tech before you start a fire and burn your house down.

My 50inch plasma LG tv has no picture only sound.

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.

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.

You've lost the standby voltage, probably due to varactor or passive component failure...accordianman
