2006 42" plasma has blank

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

Capacitor being replaced! Fairly easy DIY fix.

We have a pioneer plasma tv and there was a loud popping sound and then the screen went blank

I had the same thing happen a few weeks ago to my zenith 50" plasma tv. I tried to turn it back on with the remote and the power button on the set but the only thing that happened was the led would flash green 3 times and then go back to red. I took it to a repair shop and they called yesterday to tell me it was going to cost $700 to fix it by replacing the power supply. No guarantees either that it will last any longer than the 3 years I've had it for either. But it's still cheaper than replacing it with a new "bigger" tv which is what I will eventually do anyway. I've heard of people looking on ebay for repair parts and doing the repairs themselves but there is no warranty on human error...

Fujitsu plasma screen went blank and the LED light which generally shows green (on) or red (off) is blank (no color) as well.

Usually when these develop a fault you will get flashing LED codes. If you are not getting any the power supply may have failed completely.

Try another cable and socket in the first instance and ensure the manual power switch feels normal in action.

Plasma screen went blank.

It could be a few components like the tuner or the component that processes the still images to display on the plasma screen, I forget the technical name for it. Either way you look at it, a part has clearly blown and there's no quick fix. You'll need a professional to take a look inside it to determine what's wrong with it. However, if you're confident enough to open it up, you'll most likely see burn marks where a component has burnt out. Mind, if you open it up, not only are you putting yourself in high danger, but you'll void your warranty if you still have it left. If you do in fact still have warranty, my only recommendation to you would be to return it under warranty. Good luck!

Hi Gemma - have a look at this forum - it may be similar to what you are experiencing. Things don't look good for NEC owners I must say! Good luck Saty.
