If they tested the convergence board and thats ok, the only other Items it could be are the Digital convergence unit or the Velocity comando units that control the convergence yokes. If the convergence isnt adjustable with magic focus adjustments wont help it. Is the repair shop an authorized samsung repair facility? If you need more assistance let me know.

You can get the replacement Ics at the following link you need two STK392-040 ICs they are located on the Convergence board that should be mounted on the upper right side of the set above the deflection board. You will notice two large Black Ics with STK392-040 stamped on them. Heres the link to get the new ICs and free instalation instructions with pictures.

Afraid you have the Bad Samsung set The convergance Ic's are mounted below ot a differant board that I described. If you are good at soldering simply replace the Ic's STK392-040 there are two, if you simply want to replace the entire board the part number for youre set is AA95-00055E and it's about $250.00

Bad color, blurry, hour glass screen...


This is the most common problem with projection based sets, what you have is known as convergance failure. There are two Ic's and in a Samsung they are STK392-040's these will need to be replaced and possibly a small fuse and a few resistor. I am haveing trouble with the moidel number you gave and cant quite nail it down, but some Samsungs put these all on a easly replacable board. This board BP95-00142E is about $80.00 and avalible at www.vancebaldwin.com A easy way to tell is remove the back and see if these huge Ic's STK392-040 are mounted separly from everyother board and are mounted to the crt mount

Everybody here seems to have basically the same problem so I will write a general fix for these Samsungs. First what you got is known as Convergence failure, A Ic or resistor, fuse or some other component has failed in the convergence circuit. So finding the service menu and trying to align the colors or spinning magnets on the CRT’s or a real bad idea of tipping a CRT or mirror would be the equitant of ripping the transmission out of your car because it had a flat tire. When the convergence fails no adjustment will bring it back, and if you do one of these stupid things then you have two problems. Now most of these Samsungs have an easily replicable board that all the convergence amplifiers are on. This can be found by removing the back and seeing if there is a board about 9 X 5 inches big and mounted to the CRT mounts, there will be 5 connector to this board. Now if your set does not have this board and instead has the two convergence Ic’s (these are about the size of a playing card and have the numbers STK392-040 on them) mount down on a board below and to the right ( this is known as the deflection board) this repair will not work for you. Instead you will need to component level repair the convergence circuit. But if you do have this separate convergence board the repair is fairly straight forward. Go to www.vancebaldwin.com or some other supplier and order BP95-00142E this is the convergence board. This board has been crossed several times through the years but this is the current version. Now once you get this board simply replace it making sure to get al the connector back in there original spot. The fire up the set and run Flash focus and for about 95% this will fix the set
