Phillips 51pw936317f picture not as sharp as when new

Picture no longer appears to be as sharp and clear as when new. I have been told that it may need a new bulb as we have own this 51" read projection flat screen for over 4 years and it is rarly turned off. The bulbs appear easy to purchase, however are they easy to replace, or do I need an expert to do this repair?

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc.

You may even see halos around images.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Screen Flashing


In a Sony TV, the most common cause of the picture flashing on and off is a weak picture tube. When the set was new, it took about 5 to 10 seconds for the picture to appear once the set was turned on. This is normal. If you have been noticing that it has been taking longer and longer to first appear, this is the clear signal that one of the picture tubes is getting tired. There is a circuit called IK Blanking that monitors each picture tube and adjusts them as the tubes age, so you always see a good picture. When one of the tubes has weakened so much that it cannot produce enough brightness in the picture, the circuit shuts the picture off completely. I guess Sony does not want you to see a tired, dull picture. When the tube is right on the edge of being too weak to keep the picture on, the picture will flash on and off, and it will also take much longer beofre it first turns on. The good news is that the Sony picture tubes always respond beautifully to reactivation (CRT Recharge) but you will need a qualified tech familiar with Sony projection sets to handle that repair for you.
