Remove the back of the tv.disconnect and reconnect the ribbon cables into your buffer pcb.if this does not correct the problem replace the buffer pcb in that location where the screen is going black.you also could have
a defective panel if the buffer pcb does not correct your problem.

SOURCE: Screen lower half goes black/blank

The lower "Y Buffer" board is defective. Best repaired by a technician, or contact Phillips support for the part if you think you are able to replace a small circuit board on your own.

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.....

SOURCE: Screen will periodically go half black. Then it

When you have video display problems such as shadows and lines that go away after warming up, or come and go during viewing, it is usually the LVDS cable and T CONN board going bad. The screen can have one of the following or combinations of blurs, different layers of brightness and lines. It could be the back light but most of the problems with the LNT4661F have been this.

I had the shadow and line problem and replaced both the cable and board for $120 and that fixed my problem. Since I had the TV apart, I went ahead and replaced the capacitors on the power supply board so I wouldn’t run into the clicking problem that also affects this model TV. You can find the parts numbers for the LNT4661F cable and board below. You can find links to YouTube ( Part 1 & 2) to show how to replace the capacitors. Good luck.

Screen split with black bar through center, top of picture shows in bottom


It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
