Our samsung HCl4715W tv is all connected right but our picture is scrambled where you see double exposure and the color is off. Can not find our manual. any suggestions?


The problem of your tv is the convergence. Projection tv set has a 3 colors red,blue and green this 3 colors must be properly lined up to look the video normal. When this 3 colors is not properly aligned the video will produce a double image of color or like a 3d or wavy. In order to fix this problem you should adjust it in the menu program of your tv you should move any of the colors to up or down, left or right if you cannot align the 3 colors the problem is the convergence ic it must be replace. To locate the convergence ic you should remove the back cover of your tv but be sure to unplug your tv, you will see this ic attached in a large aluminum plate it has a marking of stk--- and followed by a numbers. or you could contact a service technician do do it for you and save you from stress. Good day and best regards.

Picture is not showing correctly. Color seems like it is going out. For example the color green does not show up as green.

Our tv just started having a fuzzy image and the auto focus function aborts during the red color alignment. is there a manual alignment I can do to fix it.


What does this fuzzy image look like? Does it have ghosting shadows. Of course it is possible to align red manually from the convergence menu. But first lets confirm that it is indeed a convergence related problem.

Image is out of focus. colors do not align


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 photos of convergence problems
