SOURCE: Black Screen after 5 mins. of use

It sounds like the entire screen goes blank with your problem. My problem is the lower half of the screen goes blank. Do you think the SSB is also the problem? What are your thoughts about the "Video Board" or the X Board?

Do you know where to purchase parts?

You can fix this yourself with a software upgrade - get the upgrade from Philips website - go to www.usasupport.philips.com, enter your model number, click on the verison of your model ending in /37, and click on "Software & Drivers"; click on the link that says "Firmware Upgrade - Software". Instructions are on the same page - make sure you only transfer the .upg file, not the entire zip file to a portable memory stick.

Good luck!

Hi Mikshanks,

I had the same problem with my TV. It was a horizontal problem with different shades of color, and black spots. I replaced my Upper & Lower Y-buffer boards. Your Y-sus board should be okay since it still powers on the screen. You should replace the Y-buffers Upper & Lower, and it should work. I hope this helps.

best regards,
Tyler

SOURCE: Black screen no sound. Red and green standby/on

You probably have a bad power supply board or one of the x or y drive boards. It is hard to say because they all give this symptom. Usually power supply though.

Philips 50" Plasma with ambilight


It sounds that there is some loose contacts to some connections to your Plasma display. Almost all plasma displays will have similar configurations to display circuits, will change only with the size of the screen. If you wish to get some details http://electronicshelponline.blogspot.com/ Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product by anyone else could result in serious injury or death. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact the nearest service centre.

Pink lines only down the middle of the screen aprox. 12" wide for spit second.


Most likely will get worse as you are describing a failing control bd. The part # is 6871QCH038A and is a fairly complicated repair. A good deal of disassembly required, and I would take advantage of your service agreement.
