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.

My tv has lots of red and green. Faces are shadowed by a red outline. It occurs on all channels and dvd.


If problem does not fix by flash focus/ convergence adjustment in Menu then replace convergence output ICs on D board of tv that sounds defective and causing problem.
Comvergence output ICs replacement requires soldering work with proper tools and electronics knowledge/ experience, call local tech if you have no experience.

Colors are out of focus and magic focus wont fix


If you have tried the customer convergence menu/control and can not set the convergence you have a fault with the electronic circuit that controls the convergence of your 3 picture tubes this overlaps the 3 colors red, green, blue to create the proper color combination's of colors for a proper picture

My Tv has red light (color) out of focus..I've tried tuning the lance but it's not the problem in the lance..it's something else..don't know what..do you?


Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here http://www.mitsubishi-tv.com/support.html

Hi:
There if this is a DLP television there is no convergence adjustment on these models as they are digital. There might be a problem with the color wheel assembly. If this is a Mit's then the optics engine will need replacing, You forgot to mention the make and model of your TV.
