Question about Samsung HCL5515W 55" Rear Projection Television

1 Answer

Convergence problem We have a Samsung HCL5515W projection tv. The blue started ghosting everything on the screen and from what I read online it's the IC's that need to be replaced. We would like to do this ourselves but do not know where to find them or the part numbers to be able to purchase them. I am told the Blue and Red need to be replaced. Any help would be appreciated!

CONVERGENCE IS OFF PINK AND GREEN LINES ON THE TV SCREEN


Projection TV2_bing.gif 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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung2_bing.gif, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith2_bing.gif, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D2_bing.gif
  • 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 - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash2_bing.gif focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

How do you adjust the focus lenses for an HCL5515w TV?


You have one of two problems. Sometimes both.

Problem #1) 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.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Problem #2)

Your TV may have a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem



  • 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.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can hire a pro. If you want to do the repair yourself check the site www.TvRepairKits.com.

Samsung HCL5515W...when using coax input pic convergence is off, red and blue seem off....when I use the component inputs it constantly flickers between the squigly lines and picture with convergence off?...


on component your device may have to be on progressive. old dvd players you could switch back and forth on progressive and normal. the squigly lines sound like you need to make sure its on progressive. hook it up using the yellow video slot on player and tv (any cable will work). go into menu and look for progressive and change it on.

Green and pink shadow on my samsung 55in proj tv what can i do to fix it. i all ready fixed red and blue line but green is way off and i dont see any way to fix it


hi, this is the early signs of convergence board chip failure. you will need to replace this board in order to correct the collaboration feature. the convergence is responsible for regulating the RGB stream in you set. if it is malfunctioning, you will not be able to regulate the red blue green streams.
