1. Wet a soft cloth in a mixture of lukewarm water and a little fabric softener or dish washing
detergent. Wring the cloth until it's almost dry, and then use it to wipe the screen.
2. Make sure the excess water is off the screen, and then let it air-dry before you
turn on your TV.

I copied this directly from the manual for the TV for you.

How to fix a Zenith Projection TV. Could it be the bulb needs replaced? Is this something I can do myself?

The whole service manual is here:
But this is something that you might want to reconsider. The availability of parts could be an issue. The smell could be the ballast or the bulb got really hot and went out. The repair process involves troubleshooting with special meters etc. You may be able to spot something that burned out though.

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!

Image is burned into the screen...

Unfortunately the image can't be removed because it literally is burned into the picture tubes. You'd have to replace them which isn't cheap.

I want to fix the convergence of a zenith r50w46

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 photos of convergence problems

Zenith projection tv model number r50w46

I read in the manual that you can turn the speakers off using the menu command when you connect up an external stereo system. You might want to check if this menu command inadvertantly was set to off. good luck
