Panasonic TH-42PD50U Plasma Television "POPPING NOISE"

We've had this TV for 2 years. We have noticed when the TV is OFF we here loud popping sounds coming from the TV. It usually lasts on and off for about 30-45 minutes after we've turned the TV off.

We just assumed it was from the heat build up. It is mounted on the wall.

Any reason for concern??

SOURCE: Power light blinking 2 times

2 blinks means the unit is having problem with 12 volt supply.
while power on you can check 12DC on power supply before shutdown.if the voltage is constant before shut down I would recommend to replace D board.

Try to unplug and replug the power cord. If TV remains unchanged you need to call for service. The power supply board was defective. In worse case, the Y and buffers are defective, too. There are many steps needed to figure out the exact defective board. You need help from TV repairer unless you want DIY.

You need to have a repair shop check it out. It sounds like a power supply problem.

Our Panasonic 50" TH 42PX75U


well it sounds like something fried inside the tv. In my experience, this sounds like your y-sustain board went bad. it could be your video board also. considering todays value of the 50" panasonic plasma, it will be cheaper to replace it, unless you are willing to spend around $300 to get it fix at a shop.
good luck

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

Loud noise


You MAY have some condensation in a high voltage path inside.
The noise might well be from leaking high voltage.

I recommend you let it climatize for a couple of days before trying it again, otherwise you may damage circuitry not normally involved with production of the HV.

Arcing noise coming from TV


Clicking, popping noise on certain channels. All connections checked for tightness, and sound is isolated to the TV, not cable box or home theater. What is the cause and fix? Does it involve an inhome service call?

If the sound isn't coming the speakers then its cabinet expansion. Specifically between the panel and the front cabinet.
I believe Panasonic has a fix for this.
