Question about Philips 23PF9966 23 in. HD-Ready LCD Television

Open Question

Philips 23PF9946 2 inch vertical line just left of centre as you face the TV, it changes colours to match what is happening on the screen before finally becoming a grey/black colour. The line takes up all of the screen and appears after a period of time 15min to 1hr and is on the screen no matter what is being watched. If I turn off the tv and then come back 15 to 30 mins later it is still there, if left longer it goes away onl;y to come back again after viewing for the time period stated.

Ok did this happen the first time u turn on the TV. ? If so u might have a ribbon cable disconnect from the logic or u might have a defective Plasma panel. If u have a defect like your describing the IC's on the panel short out and no longer work causing that section of the screen not to function. Only fix then is replace panel

SOURCE: 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.

SOURCE: 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.

It is possible that you may need to download an upgrade to a flash drive and then with the tv off, insert the flash drive into the usb port on the tv. Turn the tv on and it will load itself. Check Philips website for updates...

Parallel vertical lines through left side of Panasonic Plasma tv


This sounds like one of the driver boards at the bottom or top of the screen has an intermittent fault. The set will have to be taken in to a service centre.

Colour misalignment and focus


Inside of the tube assembly, there is a cooling liquid. This could be a job to change, and then re-adjust everything. It is also possible that on top of this, there are problems with the convergence and bias control circuits.

Typical repairs can run in the area of about $400 to about $800 depending on the amount of work and type of parts required.

Personaly, I would go out and get a good Plasma or LCD TV at this point!
