Quick Fix For A Zenith Plasma TV That Won’t Turn On


I have a Zenith 50″ Plasma Tv model Z50PT320-UC. One day it was working, and the next day it wouldn’t turn on. The red light would just blink and click. I read tons of forum posts, and I read tv repair blogs, but I couldn’t find anything that worked. I thought my 4 yr old TV was now just a giant paper weight. Well, WRONG!

All these people said the power supply board had to be replaced, which just wasn’t possible for me to do. Finally, I came across a repair man that said, “Unplug the TV, hold the power button for 10 seconds, wait a minute, then plug the TV back in.” Well, I tried that it, but it didn’t work. So, now I’m thinking great, they are right - WRONG.

After having a broken TV for a week, it hit me this morning! Wait a minute! If you unplug the TV and then hold the power button, it doesn’t know your holding it. So I reversed what all these repair men had said. I left the TV plugged in, held the power button for the 10-15 seconds (you have to hold your finger steady), then I unplugged it for a minute. When I plugged it back in - BAM! The TV turned on!!! It’s not a paper weight! I have read hundreds of people with this same problem. Please try that first! It fixed mine!!!

To summarize: Your TV may not be a paperweight. Try this:

  1. With the TV plugged in, hold the power button for 10-15 seconds.
  2. Unplug the TV for 1 minute.
  3. Plug the TV back in and turn it on.

So... what do you think? Please leave me a comment.
