Can you look into the blue lens when the set is playing using a hand held mirror and see if there is a picture in the blue CRT. If not you will need a new tube for the blue. If you do need a tube let me know as I have a source for good used tubes that are very reasonably priced.

My samsung HCM4216W TV has 3-D effect i was told it is a conversion module for the bulbs is this right


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.

The green and magenta convergence on my tv is off. The picture is also...concave(?) I've tried unplugging the tv for 10 minutes and the solved nothing. What else can I do?


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Red and Blue convergence issues cause triple-image


This sounds like your convergence chip is bad. If you are good at soldering you can order the replacement kit from www.tvrepairkits.com and do it yourself.

Blue and Yellow doubles


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.

Replaced bulb and converge problems


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.
