Question about Philips 42PF7320A 42 in. Plasma HDTV

3 Answers

Half the screen has gone black

My Philips 42" Plasma (42PF7320A/37) screen is half black. It seems to come and go often and has gotten worse these past few days. I've already done the latest software update. It seems to fix when I hit the back of the tv. It's an old school way of fixing things I wish I didn't have to resort to. Any idea on how to fix? I'll take the thing apart if I know where the fix is.

    Just wait, it's gonna get worse and end up being permanent instead of intermittent (horizontal lines all the way down the screen.)



    Sorry, I am looking for an answer for it too.

    The top half of the tv would go black. Bumping it would help. Then evenutally the entire tv went permanently black. For the price of the tv, hsane on Phillips!!!!!

    I'd like info on this too. Mine has started doing the exact same thing. After about an hour of viewing, the top of the screen goes black while the bottom half of the display is fine. I've had the TV for about 2 years so it is now out of warranty. By searching the Internet, I've found some postings where people have said it is related to bad soldering and/or loose connections on the boards (or power supply issues).



    I called Philips and was told to call a service technician. I could a couple and have been told it would be at least $200 plus the cost of any parts to get it fixed.



    I've also emailed Philips to inquire about why there has not been a product recall for this issue because I've seen quite a few people who are saying they have this problem (Philips and Samsung - who apparently used the same components in some of their plasmas).



    I'm still looking for solutions because I'm sure this will get worse. I'm hoping Philips will offer to cover the repair (or at least part of it). $2000 for a TV, you expect some level of quality, and having to pay for a manufacturer defect... well... sucks!

Ok first lets start with the half screen and no lit screen . Samsung plasma panels (S42AX-YD01) HD V4. are really bad about the Y-board (upper,lower) buffers are really bad about getting hot and burining up. If u remove the back cover of TV u will see on the left side the Y-board (it will be marked in small letters) if u look and the rows of IC's with heatsinks on the buffers will be a dark yellow. Majority of the time if u remove the buffers. and look underneath them u will see the solder has melted from the board. U can replace the Y-board and buffers and the TV will work fine.
Next part if u have vertical lines in the panel. There is not much u can do as a repair. Only thing u can do is get panel replaced. because there is and IC that is burned up on the panel, and trust me there isn't anything u can do to fix it. If u want to see for yourself. After removing the back cover, remove SSB, and brackets holding PDP in place. at the bottom of TV there is a row of buffers marked E,F,G, ( i think) there is a long heat sink covering the IC's at the bottom connected to the bottom of PDP. As u can see without a $70k machine to change this there is not much u can do with it. Hope this helps.

We ended up purchasing an extended warrrentee from Sears. They ended up replacing everything inside the tv. Then the screen itself went bad. They ended up giving us a discount on a new tv.

This is a bad screen. The whole screen needs to be replaced. I got a replacement screen by watching my local craigslist for a Phillips that wont turn on. It is also a Samsung screen but I forgot to write down the part number before I closed it up.

No picture, sound ok


I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.

Phillips 42 inch Plasma -Screen Issues!!!


intermittent loss of picture on either bottom or top half of screen is specific to y buffer boards located on left side of screen going from top to bottom when looking at back of tv. the y lower buffer would be the board to replace to resolve the loss of bottom half of picture. if the top half also is going out intermittently could tied to upper buffer as well but just a note the y main board to right of these buffers drives those two boards so in some cases could also be part of the problem. if only bottom half is affected i would recommend replacing lower buffer only
