Red and Blue convergence issues cause triple-image
I recieved a Samsung HCM4216W from a moving neighbor. Both the red and blue convergences are slightly off, but I cannot read the menu to fix them. Can anyone give me a step-by-step walkthrough on which remote buttons to press to fix this triple-image problem?

I'm not sure what you mean by the "lines". If you mean the image looks like "double" (or triple!) vision, then you need to adjust the red/green/blue convergence. This is especially noticeable with white images on dark background (like text of credits). If this is it, check you manual or explore your menu via the remote. Sometimes convergence can be a problem if the tv was moved or experienced large changes in temperature... or sometimes all by itself!
ll 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.

Well, fortunately the television that you purchased has an auto-convergence feature. What is happenning is that your color lamps are misaligned, did it get moved at all recently?
Anyway, in your menu you should see a "Convergence" menu, and inside that menu, a section called "Perfect Focus". Run Perfect Focus in this sequence: Green --> Red --> Blue
After that your picture should look great, if not try tinkering with the manual adjustments on the "Convergence" menu. Here are some URLs that you might find helpful: (just copy+paste into your browser)

After replacing a Picture tube convergence/geometry allignments can be quite extensive and if they're not fairly precise the sensors for the auto conv. can not be calibrated therefore your auto conv. not working as you described. The key is usually the geometry start with the green lines and get them as square as you can then align the red/blue. Since the auto is not going to blue that often means the blue is to far out and the sensors are not picking it up.
The Samsung has bad convergence IC's most likly. This should be repair ONLY by a trained technician as a TV set is not a place to experiment or tinker with because of the extremly high voltage inside. This repair should cost you in the range of 250 to 400 bucks . Good Luck
