    Yeah my RGBs are all pointing in different directions causing bars of extra colors on the sides of the picture causing a wanna be 3D look and I have no idea how to fix it.

    I seem to have the same rgb problem's s the others. The pics posted are identical to mine. When watching a movie or doing powerpoint, everything has a yellow, green, or blue ghost outlining images depending on what side of the screen the image is on(right or left). Is this something that can be fixed myself, or does it have to be taken in, or is the projector junk? Please let me know if anyone has any ideas. Thanks

We had the same problem, and it seemed to fix itself when we did the following (not sure exactly what it was we did, but it worked):
1) Remove the outer box on the right side (one by the lens), rear, and top. (you'll need a T9 torx screw driver with a long shaft as the first 4 screws are on the bottom under the rubber feet and caps on the front corners of the bottom.)
2) On the top is a board that has 3 orange cables coming out of it as well as some others. We completely removed that board and reinstalled it.
3) We determined that the 3 orange cords control the color out put.
4) So leaving all of the outer sides off, when we reconnected the board and provided power, the image came out properly aligned.
5) We're now struggling w/color. Based on how you insert the orange cords you get different color saturation. We seem to be missing a proper/consistent red display.
6) But the colors are all aligned and the image clear. We're getting there . . . .

Be very careful!!! You could electrocute yourself.

The adjustment requires disassembling the projector. It's not really something that should be attempted in the field.

Phlips proscreen 4750, how do i open up the case to get to the inside/ and how do I adjust the convergence?


There is not a lot you can do with it, even setting up the static convergeance as you require a crosshatch generator, dot generator and specialist tools to adjust the LCD immagers.
It is not practical for the laman to attempt an adjustment of this sort.
Take it to a Philips Specialized Repair Centre.

Philips Projection Screen TV Model PTV915 Horizontal Alignment


Problem solved, needed to get the universal remote i was using set up with the proper code. Once I did that I was able to use the remote to set up the single & multi-zone Red & Blue Alignment.  I also pulled the back plate off and manually adjusted the RGB focus knobs. It seems to be working just fine now.
Thanks to all the other posts.

Colour misalignment and focus


Inside of the tube assembly, there is a cooling liquid. This could be a job to change, and then re-adjust everything. It is also possible that on top of this, there are problems with the convergence and bias control circuits.

Typical repairs can run in the area of about $400 to about $800 depending on the amount of work and type of parts required.

Personaly, I would go out and get a good Plasma or LCD TV at this point!

RGB not aligned so I get thin red vertical stripes displaced to right of icons


If you are handy with allen wrenches, quality screw drivers, and the like, you might 'try' opening up the can of worms and gently manipulating the red LCD panel (it will be obvious--a magenta color when off), by slightly loosening the holding screws, then moving--ever so slightly, the panel untill the ghost disappears. Do not do this though, untill you mark the present position on the top and bottom of the LCD panel. Take pictures, far and close-ups, as you go so you can reassemble the unit. The typically three LCDs can be located by finding the prism cube, located under the circuit board, and just before the output lens. Be patient, and have fun. I did this with an 'out of wack' throw away, and now it is just as enjoyable as my 'dimmer' HDTV projector. Even side by side, from 8 feet away, when both are making 72" images, the HDTV is barely clearer, Jon.
