Question about Zenith R50W46 50" Rear Projection Television

3 Answers

Zenith R50W46 My colors all went haywire. My tv mostly shows green, no matter what adjustments you make. Someone said the convergence was bad, or my tubes were out of line. Run convergence but it doesn't change anything.

Yes could be a convergence issue, but if you get no results with adj it will need the convergence boards worked on / replaced. ie you need to call a tec. to look at it, this is not something that will fix without pulling it appart.and performing repair work on it.

Take it to a TV repair place, they charge $50 to look it over and tell you what it takes to get it back up. This is your cheapest way out if you want to try to keep it.

Shadows of green and red in picture


projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

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. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

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.

Colors are misaligned on my zeneth r50w46 and the auto convergence option did not solve the problem. the red droops off on the left side of the screen and the green droops across the top center.


Your convergence IC's are out and this is why you can't use the auto or manual convergence. This type of repair done at a verified Zenith service shop most likely will run you $400.00 to $500.00 dollars. However, if you have some electronic skills and are familiar with soldering and de-soldering, you can do the repair yourself for around $85.00 to $100.00. You will need to buy a convergence repair kit which has all the parts you need and gives pretty straight forward instructions. Plus, if you run into trouble, they have online support. Here is the link for the convergence kit.

This is not really a hard task to do. It usually takes about 2 to 3 hours from start to finish if you take your time and make sure you follow the instructions to the letter.

Again, if you don't have any sort of electronic skills, it is always better to have the unit serviced by a professional.

Good luck!

Color mostly green


Sounds like tyo me that the picture tube is getting soft on ya!!. Its a common factor that occours with all tvs but mostly with zenith. A service tech might be able for a small fee rejuvinate the picture tube but theres never a warrantee with this type repair. Its not something a user should attemp to do as theres hi voltage inside this set even on the tube socket after its ubplugged for awhile. Seek the advise of a repair pro to see how bad the tube is. Good Luck
