Colors in left upper corner like a rainbow and fuzzy warped picture with lines that will run thru the picture from time to time, majic focus does not clear this up and I can not get the color set correct, to much red.

logitech cams only work in UVC mode not drivers

unless you have 10.3.x software on the mac. then you can run 8.0.1 on the mac. otherwise you need to upgrade the cam.

here is a list of mac complaint cameras.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

about 400.00 to repair

replace the two convergence IC's
Sony convergence problems

Repair the convergence circuit

Have you let set warm and then tried Magic Focus? Maybe after 15min.

If this is a projection tv then replace convergence amps. and resistors in the area also look for open fuses.

I just had my lower Y-buffer board swapped out to fix a problem similar to yours. After an hour and a half of on-time, the lower half of the screen would flicker on and off with the same appearance you mentioned. Changing out this particular board fixed it for me. However, since it has gone from top to bottom on your set, it may be more of a main board problem for you (that controls both upper and lower halves). Beyond this, I don't know any more. I am considering getting a service manual to gain more knowledge about the various PCBs in the unit so I can fix any future problems myself.

get a shop manual,it tells how to do the whole convergence process and how to store it to the rom memory to save it.
