My plasma screen goes black on bottom 1/2 of the screen

My Magnavox 42" plasma, the bottom half of the TV screen goes black off and on, the warmer it gets, the more frequent and longer duration of the black screen. Any ideas?

In most cases the lower Y-Buffer board causes this issue. Unless you know how to work on a TV it is suggested that you have a technician look at the TV and repair it for you.

SOURCE: Bottom half of the screen goes black frequently.

You can start here: http://www.support.philips.com/support/catalog/catalog.jsp;jsessionid=87CE21B6A8264B83B8D00501ADACA8BF.app107-drp1?_dyncharset=UTF-8&country=&categoryid=FLAT_TV_CA_US_CARE&userLanguage=en&navCount=1&groupId=TV_GR_US_CARE&catalogType=&navAction=push&userCountry=us&title=Flat+TV+(plasma%2C+LCD)

Enter the exact Model Numbere in the search text field.

First verify the exact Model Number of your TV. Mine is a 42PF7220A/37.

go to:
http://www.p4c.philips.com/cgi-bin/dcbint/cpindex.pl?ctn=42PF7220A/37&scy=us&slg=en

On this page I found listed under "Software2.gif & drivers" the Firmware Upgrade Software 42PF7220A/37 v1.5.0.0

I downloaded the compressed file and extracted it to a USB Flash Drive2.gif.
After you extract the file you will have 2 files...."autorun.upg" and a "readme.txt".
Print out the readme file the delete it off the USB Flash Drive2.gif
Make sure the USB Flash Drive2.gif has only one file on it (autorun.upg)

Make sure the TV is turned off.
Put the USB Flash Drive in any of the USB ports on the TV.
Turn the TV power on with the Power Button on the righthand side of the TV.
The TV will display an Update screen.
Let the TV run through all 3 processes.
Turn the TV off and remove the USB Flash Drive.
Power the TV back up.
Hopefully the Updates fixed the problem.....

While watching tv half the screen goes black

Download software from the Phillips web site. Use a usb flashdrive to transfer the download to the TV. This worked well for us and our picture is better than ever.

Picture goes black on bottom half of the screen

You have a bad connection to the panel or bad caps on the boards. Not something for the DIY'er. High voltages in plasma sets.

Replace lower scan converter PCB, which plugged into Y-Sustainer Board, located to the left of the display if you poke back cover open. There are 2 of them, but in some models might be the one, long PCB.don't wait to fix it! otherwise, you will knock out Y-
Sustainer and upper scan converter. That will cause you to spend few hundreds to fix it.

Model 42mf231d/17 42" plasma

If the loss of picture is either on top half or bottom half of screen. there are y buffer boards that go from top to bottom on left side of screen when looking at back that control those sections. when there is loss of half of picture then buffer associated with that area would be at fault and would need to be replaced. when i see a degrading symptom such as loss of picture on top half or bottom half leading to no picture issue normally you would check heat syncs on y sustain board and if not heating up after a few minutes of being turned on would recommend replacing y main and both y upper and lower y buffer boards as they complete a circuit

You have a Ysus problem. Sounds like a cold solder joint or loss connections on ysus main board.
