Question about Zenith R57W46 57" Rear Projection Television

1 Answer

I have a Zenith R57W46 57 in Rear Projection Television colors don't align.

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....

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.
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.

Picture of a set that needs the fluid changed.

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

My zenith hdtv model#m52w56lcd has a green tint.


Go to the Zenith web site. If you have not adjusted any of the default settings for color, brightness etc then a possibility is that your light engine is failing. Just this month a Class action settlement was put in place that entitles owners of this and several other models to have the light engine replaced in home under an extended warranty until July 2010. You should be able to find a toll free number if you follow the link to Class Action Settlement. I did and a service tech is coming to my house next week to replace it at no cost to me. I looked and the parts alone are approx 600 to 1500 bucks. Good Luck!!
