SOURCE: Vizio 50" Plasma VP50

Hello SuziCanevaro,

This may have been the sound of electrolytic capacitors exploding. I would not suggest plugging the set back in until you can have it checked by a qualified TV technician. If you are skilled in Electronics and would like to work on this yourself, you will need:

The schematic diagram, a multimeter, a signal generator, an oscilloscope, and an isolation transformer.

I hope this helps,

Thank you,

SOURCE: made popping sound then picture went black

I have the Vizio JV50P (Plasma) after 2 months it's started to make a loud pop sound then no picture. Vizio sent a third part repair man to replace the power board, main board, left and right sustainer boards and no less then 24 hours later... I had the same issue. I was just on the phone this evening with "Vizio level 3 support" and they out right lied to me. They told me they never heard of this issue before and yet it all over the internet. Shame on me for not searching the internet more thoroughly for known issues with Vizio products. If I had I would have easily found the term that seems to have associated itself with the Vizio’s line of flat panel TV’s ‘The Pop Of Death”

I am current climbing the Vizio Org Chart to get my money back. I have spoken from level 1 thru level 3 tech support. Who were willing to replace the defective unit with a refurbished unit!!! NO WAY! Then I spoke with a customer service rep and then his supervisor. “No Help!!!” They read from a script and showed no compassion for my issue. They too wanted to send me a refurbished set that is only covered by the balance of my warranty! A set that has the same issue that they can not even prevent from occurring and sets made as recent as 9/07 (manufactures date), new sets! I just left a voice mail message with the Customer Service Manager of Vizio corporate (aka V, inc.) and will await his call back tomorrow. I then searched the internet and found the term that seems to be growing in association to Vizio… ‘The Pop Of Death’ I can not wait to hit him with that term tomorrow! If I do not hear back from him, I will contact his superior. It’s very easy to find that information on the BBB. As far as I am concern Vizio is not only a poor product but a deceptive company who so far does not stand by their product. I will follow up this post in a week or so.

SOURCE: I heard a loud pop

Does anything come on the screen? Input display box? 
If no:
Sounds like it could be a blow capacitor. Cheap part, but need someone with a little electronic know how repair to fix it.

Samsung plasma screen went black. Was watching tv, heard a loud pop and the screen will no longer turn on. You can hear the tv turn on but no picture. Power is still working, just a blank screen.


Issue is either with the X or Y sustain board. Look for a cap that has blown or a cracked solid state device on the board. One of them is responsible for the ***** croak you heard.

Why does my samsung plasma 550 have no picture?


It sounds like a capacitor blew in one of the internal circuit boards. A capacitor makes the pop you described, and techs actually refere to them as "being popped".

Pop sound then no picture, just sound


I assume this is a plasma TV? You will have a fuse blown on either the Y or Z sutain board, there is also a possibility one of the driver IC's has blown on the buffer board, this will shut down the screen & leave the audio working normally. You can check these boards which sit on the left & right hand sides of the screen.

Blown Picture


There is not much you can do to fix your plasma. Since the plasma is less then 1 year old, still under Samsung warranty.
I would suggest to call them to fix it.
Good luck.

Loud pop - no picture


Your X and Y circuit boards are bad. It might require the replacement of the power supply as well. This is not uncommon for LG/Zenith plasmas to have this issue. Not a do it yourself repair.
