Question about Samsung HCL4715W 47" Rear Projection Television

1 Answer

Blue Convergence problems

I have a Samsung TV, Model #HCL4715W.  The tv was given to me and it is horizontally pinched from the top and bottom and the blue convergence will not move when I try and adjust it.  I have researched the problem and it sounds like I need to replace a part called the IC STK392-040.  If this is so please let me know if there is anything else I need to check.  I also have no clue on how to fix a tv, but I am very good at following directions and have fixed electronics before and know how things work.  If you could email me a description on how to repair it or what I should do that would be great.  Thank you

Yes thats what you need. Just go to radio shack get a de soldering Iron (the kind with the rubberbulb works fine) as wel as a fine pointed low wattage Iron. Also pick up a tube of heat sink compound while your there. Then lable your wires on the tv that you remove. Desolder both STK392-040 chips and solder in the new ones. Just ve careful not to bridge any of the pins with solder chck them with a magnifying glass. Dont forget to coat the back side of the new heat sinks with heat sink compound. You will need to adjust the convergence when youre finished. Just go slow it takes about an hour. I would also vheck the resistors right next to the ICs at times on or two of them get burnt when the ICs go out. Heres a link to where you can get the replacement ICs.

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.
