Samsung HCL4715W-has blue shadow

Approximately two years ago we had a color convergence-shadow area #B393222474 Auth AE001752393QU replaced. Thank goodness it was still covered under warranty as the repair tech said this would have costed over $700.00. Which picture tube has gone out again.

    Would it really cost $700 to have a repair person fix it or can you order the part online? Thanks so much for your quick response.

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.

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.

I have a samsung 50? inch projection tv i bought approximately 4 years ago. We are overseas and now the picture shows in double, as if i am watching 3d movie. I would love to keep it but how would i be...


maybe you can have someone send the parts you need and maybe you can find your model and chassi number here for the schematic
http://www.eserviceinfo.com/equipment_mfg/Samsung_2.html
but it sounds like you will need convergence IC's to fix the color alignment , but some bad resistor or resistors will most likely be involved

here is an example of the convergence IC's

and they can be ordered from an electronic parts supply store

All screen is red


IF THE SCREEN IS ALL RED WITH VIDEO VISIBLE AND RETRACE LINES. ADJUST SCREEN CONTROL IN THE FRONT FOR THE RED TUBE ONLY. TURN CONTROL COUNTER CLOCKWISE. IF THAT DOESNT DO IT THE TUBE CAN BE REJUVINATED.
