Question about Philips Magnavox 9P6034C 60" Rear Projection Television
It is especially hard to watch when its daytime because the sun adds a glare to the screen making it even difficult to view the screen. The picture is not completely black. We can make out what we are watching easily, however the color is just darker. When we watch at a different tv in our house, the picture is significantly clearer than the phillips.
Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include....
Here are some pics of convergence problems.
What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.
Common 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.

Yes there are several and the ones I am posting for you have been used by folks who I know. You will most likely need to get the telephone number and call around, and they will probably need the exact dimensions of the screen good Luck http://www.projectorcentral.com/screen-suppliers.htm http://www.screens-usa.com/largescreendisplays/index.php http://catalogs.infocommiq.com/AVCat/mcs.cfm?mlc_id=223&SID=972124&mrc_id=1495&SUBCATID=1170

SOURCE: Picture size too large
We have the same problem with the same model. We already had the main board replaced. The picture has gotton so bad that you cannot adjust the pixels anymore. Well, you could never get to the pixels that were off the screen because the picture is too big

What you're describing is probably contaminated coolant in the crts. Between the outer part of the crt and the lens is a chamber filled with a coolant (ethyl-glycol) which can become contaminated and cause blurred picture. I'd strongly recommend taking this to a shop the procedure for changing these is a bit beyond the layman level.
Remove Crt assembly. Mark the Crt lens position for accurate reasssembly.
Mark the centering ring's postions to make easier realignment and carefully remove lens assembly by removing the four torx screws. Keep Crt assembly vertical so you won't leak the fluid...
Remove the inner lens by carefully prying up on the edge of it.
Dump out the fluid in the sink and wash the face of the Crt and chamber with water to remove all the fungus and crud. Flush the chamber with isopropyl alcohol to kill all the fungus and dry thoroughly.
Reassemble inner lens and outer lens and tighten all four torx screws.
Remove side filler plug and fill chamber with approved new Crt coolant, reinstall and converge.
Repeat this procedure for the other two Crts. It will need this done whether it looks clear or not !! The green and blue Crts in this unit are prone to this failure.
Hope this helps

When You say glare are you refering to the color bleeding off an image, or is it more of a halo effect around a certain color? Color bleeding is a sign of a shorted gun in the CRT whereas a halo or hasiness around can be CRT coolant needing replacement. Which mode do you have.
