Question about Philips Magnavox 55P9271 55" Rear Projection Television
It started this morning the colors are tripled(red, blue, green) I did the manual convergence and fixed it, until hubby turned it off and voila, its screwy again, I dont know what I did this morning to fix it, I cant figure out what the blue and red convergence things are when they put up more than one "t" to align. Please help!

Actueally convergence controls by the two IC's called STK.And surely these ic's getting malfunctioning.Therefore you have to change it (Both two IC STK) with the same part number.
This will surely resolve the issue.

You have a convergence problem. Here are some of the most common symptoms.
Screen looks 3D
One or more colors can't be adjusted when when using the convergence menu.
Screen is bowed in but stationary.
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself.

Your TV most likely has one or more possible problems.
Problem #1: Convergence Chip Failure ( common problem )
Here are some of the most common symptoms and example photos of a convergence problem
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.
Problem #2 CRT Fluid is Cloudy
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.
Picture of a set that needs the fluid changed.

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.

SOURCE: cannot converge colors on screen
This happens when convergence out ICs become defective.
Replace convergence ICs on D board to get correct picture. This qualified TV tech job.
