No but the board which is on the upper neck of the green CRT could its the velocity board which has an effect on all 3 tubes convergence.

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.

That sounds like a solder issue on one of the CRT drive circuit boards. Check the CRT boards for bad solder joints especially on the socket connections.

Not really, its possible that the Convergence yoke rings may have gotten misaligned when installing them onto the replacement Tube. Usually you need to realign when installing a new tube.

No blue manual convergence - Samsung pcj522r


Thats a very strong possibilty the phosphorus may be burned off the CRT face. Does the blue project when powerd up and looking in from the raer of the set? Look into the blue CRT lens while its playing If you can see a clear picture I would think that you have some open resistors in the blue circuit, If you cant see a picture its time for a CRT. If you need a CRT let me Know I have a good source for them Used.

Convergence Problem


I'm not a 100% positive this would fix your TV, but I found the convergence board on PartStore.com for about $80. Hope this helps.

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
