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.

You have a bad convergence board. Replace two of the STK 392-040 ICs. And check all the resistors that are next to these ICs. Rplace the resistors as neccessary. This will repair your TV. Thanks for asking...sorry it took so long to find you!

I was watching tv and it wont turn back on its a samsung hcl4715w/xaa!

Prior to failing was the video looking distorted.

If so it may be a convergence short causing the shutdown.

This is a common problem.

I was watching my HCL4715W TV and the picture

It sounds like one of the convergence Ic chips is bad---you will need to locate and replace both of them and look for any damaged parts around them; there usually are two pico fuses in this area, one for each IC. The fuses do not look like glass fuses--they usually are green or orange in color and will have the amperage marked on them and on the top of the circuit board.

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

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.

Hope this answers your questions. Best of luck.

This tv has been a nightmare, its been down 3 times in 4 years.

The convergence board, AA95-01799G is available from for about 122 bucks + shipping. You also may need to get the service manual so you can do the convergence alighnments with this set when you replace the board. You will also need the manual to perform the perfect focus alighnment on this set if you have that feature. Good Luck
