Unable to align red crosshairs in horizontal range

No there are no quick fix options for this fault. The convergence amplifiers operate similar to a high power audio amplifier, so if there is an impairment anywhere in the system, it will result in distorted audio, or in the case of television convergence amplifiers, one or more colors won't align. The convergence power pacs need to be replaced and the out of tolerance precision resistors located near the power pacs need to be carefully checked and replaced as necessary. And the power supply fuse links to the power pacs checked and replaced as needed.

It is also possible that there are root faults that cause the amplifiers to go bad which include bad connections or a bad digital control module. This repair is possible for anyone having basic electronics knowledge and soldering skills. After the above repairs are performed it may be necessary to perform the static convergence realignment procedure using the outer cross hairs as you mentioned, and realigning them.

Convergence no good on lower corners and upper screen

I'm assuming you used STK392-110 for a replacement. You could use STK392-150 for greater reliability and don't forget a good heat sink compound. (VERY IMPORTANT). What it sounds like is something even the best of techs battle. You probably didn't buy original Sanyo STK's but instead got a couple of the JApan knock-offs. Might I suggest you carefully replace them again and this time order them from B&D Electronics, on the net. You are assured of getting quality OEM replacements that way... We've had a bad batch that purchasing ordered quite some time ago and 2 out of the 14 ordered worked.. The rest were DOA (dead on arrival). Good Luck Bill

Sudden discoloration, ghosting, bowed horizontal lines in top and bottom of picture

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 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
