HI,

It is a convergence problem.

FEW TROUBLESHOOTING STEPS YOU CAN TRY:

1)Do a hard reset by unplugign all the cords of the TV and then plug it back after 4 hours.

2)Check the line cord. Wiggle both ends near the molded part.
TWO: Make sure you have power in the outlet by plugging a lamp into the same exact outlet.

3)Do a hard reset; merely unplug the line cord but leave it unplugged for 4 hours before powering up again.

The whacking test is to just bang or smack the set with your hand on the back, side, top, etc., to see if there are loose connections or cold solder joints inside that are acting up. If so, the banging should knock them back to normal and the set should restore. You might have to use some creative banging and some have had to put a book or magazine under one corner to torque the chassis enough to get it to work reliably.

If this does not solve your problem then the only solution to fix your the problem is to get it repaired by a technician

Goodluck,
Please don't forget to rate the solution.

The color is faded what do I need to replace?


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

If you are in the US please help out the service people and let them do any schematic probing for you. I once worked for a depot facility of Philips near the Dallas area, and those guys need the work ; )

If you still get snagged on the proprietary stuff, try locating a similar
tv system, and see if you can locate their schematic. Sometimes the
chips are 'basically used the same"..but knowing Philips they have their
own set of chips.

Color!


the dull and faded color could mean you need to change the coolant.
you could also try and adjust your convergence.

Yellow tints on screen and color is faded.......


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.
