Re: Panasonic plasma TH-50PZ800U

well, it was a loose ribbon -- I watched this YouTube video below and made me realize it was a loose ribbon:

So I made sure all the ribbons were fastened in securely and yeehaw it worked!

Thank you so much KevinCro! I really appreciate it.Re: Panasonic plasma TH-50PZ800U<br ...B59849DM[/url]

Re: Panasonic plasma TH-50PZ800U

Hi, I replaced the lower-y buffer board with a used, tested board:

TH-50PZ800U TNPA4407 Plasma SD Scan Drive Down Board Unit

There is somewhat of an improvement. Now, instead of a completely black lower screen, I now get thin black horizontal lines.

Is this a bad replacement board do you think? Or a lose connection somewhere?

See the picture below. Thanks so much! Steve...

ok thanks for the tip

Hello, the lower half of my Panasonic plasma TH-50PZ800U began showing problems about 10 days ago. When I first turn on the TV, the lower half of the screen is completely dark. After about 1 minute, some flickering video appears. The picture gets progressively better so at 3 minutes there is noticeably less flicker. After 10 minutes, the picture seems perfect. (note the photos below in which the picture gets progressively better over 10 minutes).

The time it is taking for the lower half of the screen to turn from dark to 100% working seems to be taking longer as the days progress....

hi, i have a Panasonic plasma TH-PZ800U that is not working properly. I have a feeling it's a faulty Y-board. I will post in another thread shortly. I am glad there are people here willing to help!
