My screen on my samsung hcl4715w has split into blue and red pictures right next to each other. I have a feeling that it is a bulb that is out. I just need to know which one.


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the 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,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV2_bing.gif may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Samsung three colors on screen, out of focus #hcl4715w


It is a convergence problem. The IC's (integrated circuits) or STK chips or the "guns". You have a red,and blue, IC's that provide all the colors. When the colors are out of convergence, you get ghosting or what looks like 3D pictures. I haven't been able to locate the part numbers for the IC's or STK chips but have located a convergence board. No luck determining if IC's are included (a phone call first to verify) but if they are, would make life much easier for you to install. Part # is BP95-00415H http://jr.partsearch.com/Part/Samsung/Samsung/BP9500415H/New.aspx?ModelMfgName=Samsung&ModelBrandName=Samsung&ModelNumber=HCL4715W

Typically, IC's cost around $10 or less. here is a link to a guy who provides pretty good instructions on replacing the IC's along with pictures.
