    I have almost the same problem. TV's colours are perfect but it sometimes turns off by itself and restarts after hitting the power button couple of times or pressing the power button on remote couple of times... will be highly obliged if solution is provided in detail as I would prefer to do it by myself...

Hi, I own a Samsung hcm4216w rear projection TV. TV has video and audio initially. After a few minutes video disappears but the audio continues. The video does not come back, only after the TV has been...


You need to notice if the video goes gradually or suddenly. If gradually then you have a solder connection bad that supplies voltage to the filaments of each CRT or tube. This is usually found off the high voltage transformer pin connections. If suddenly, then you are loosing high voltage and could be a bad solder connection as well around the high voltage transformer. Another problem could be loosing vertical deflection on the vertical deflection IC with bad solder connection on one of the pins. You can determine if this is the case by turning up one of the screen controls: red green or blue to see it it shows a line across the screen

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.

My LCD tv model LN46A650A1FXZA picture turns green after about being on for 5 minutes. Then is gets fuzzy and green


I have the same issue. TV is ~ 2 yrs old. Ruled-out cable-box & HDMI cables (green present in menu mode with no cables attached).

Screen turns mostly green, with a crappy picture. After a few days, a normal picture just appeared. Today I powered-on, the green screen stuff came up, then a minute later a good picture for about 20 minutes, back to green-stuff for 10 seconds, then good picture.

Did chavez_debi get her issue resolved?

Samsung hcm4216W turned off by itself loops.


Instead of typing model number of your TV (that located on right hand side and on the back of TV) you published here part number of your TV's remote control. LOL.
Anyway... If it is LCD/plasma panel that you talking about - than power supply have bad electrolytic capacitors that have to be replaced. You can recognize 'em by bulged/swollen tops (instead of flat tops of good capacitors).
This repair required soldering skills.

Samsung HLR5067W goes from a normal picture to snowy green color


Greetings!

I hate to be the bearer of bad news, but it is not something that has a quick fix. Without inspecting it myself it is impossible to say, but the last three of these that I have seen have been bad digital boards and can be a real bear to change, even when you have experience.

I would get slightly different video symptoms when I would switch between the coaxial input to the component input to the HDMI input. But in all cases my on screen display and menu were anomally free. Hope this was helpful, even though I don't think it is something you should attack yourself.

Good luck!

Samsug rear projection tv, everything looks green


Dust accumulation in color wheel, light tunnel, chip area can cause green tint.

It is very delicate area, light tunnel and chip can be easily damaged. Remove light engine assembly and color wheel. Blow dust out. Re-assemble. If the gasket around the color wheel housing is not replaced in the right position, or the housing screws not tightened correctly dust will contaminate the color wheel/light tunnel area.

Call someone that has done it a few times. If near Calgary, call me.

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.
