It is a 2004 made in Mexico. I Had a sears Tech come to my house and replace the STK Cards on the convergence board as well as 2 resistors. It did NOT fix the problem. The Menu does not let me go to the convergence selection. where it says Convergence, It is Transparent and unable to click on it. How do I do a Factory RESET?
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.
SOLUTION #1
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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.

Check the resistors associated with the STKs, and sometimes there is a fuse or two to replace.

I also do Not have the origional remote controll. Mine is a Philips Universal Remote Control that is Programed to this Zenith.
I'm getting all propper ohms and voltage throughout the convergence board. I just need to find out how to do a factory reset on the tv itself. Please help
