Hi,

I have a Philips 23PF9966 23 in. TV which runs fine for about 5-10 min. then half the screen goes out. After it has been on for half an hour or more the full screen comes back up.

You have a either a faulty capacitor or transistor on your units' board you will require a tv technician to do the repair for you.

MY philips 42 inch plasma TV model 42pf3320/10 screen goes black after a few mins sometimes. what can i do to fix it???


Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

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.

Flickering in half screen after 1 to 2 hours


Probably caused by a power supply nearing its death.
Try to verify this by placing a portable fan to the side of the set with airflow directed at the vented sides.
If this lengthens the operating time, there is a good chance that some minor components in the main supply have developed low values of capacitance and higher losses which worsen with warmth.
Listen closely at the vents with the sound turned down to attempt to detect a squealing sound while the TV is in its failure mode; if you find this, it is also a sign of power supply trying to die.
A tech equipped with a capacitance meter that measures losses at the same time, could find and replace the weakened parts without a whole lot of labor and little cost for parts.

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.

Top half of screen goes black


Sounds like your having problems with your Y-main(upper buffer) is getting too hot. The IC's located on this board are really bad about going out a lot. If you take the back cover off your Plasma. U will see that the manufacture of the panel is Samsung and the panel model is probably S42AX-YB01. you should be able to purchase the board. probably will run about $ 150.00.
Hope this helps
