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.

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.
The tv have a problems known as a convergene problems,it dead.Tv have colors lines R,G,B mis alignments,have colors shadow pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.These parts on the tv convergnce board,must be replaced to solved the tv picture convergence problems.Can u do basic things like take things aparts and install another things into it placed?Yes?Try website like Tvrepairworld.com to buy a whole refurbish convergence board for the replacement.The DLP tvs Samsung/Akai tvs used the same convergence board.Or the shop,will cost u like $300-350 for parts and labors.
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
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.
you need to replace both the convergence ICs number STK392-040 you can get new replacement ICs at the link I am posting and they include free instalation instructions with pictures and free tech support. Heres the link. http://servicemanuals.vstore.ca/
first of all in setup mode(where convergence is)select blue screen off.then go to picture mode and either select a set mode,or enter user and manually set contrast,brightness,colour,sharpness and tint.you can acheive near hd quality this way on non hd projtv
