Question about Samsung PCJ522R 52" Rear Projection Television
The picture has a curvature to it. It is great in the smack middle but as it moves to the sides the colors seperate and looks like I am seeing in third dementions! Can you help me? People told me to adjust the mirrors inside. I opened the back to find only one huge mirror connected to the back panel and the three color lenses on the bottem. So now I am clueless!!! Thanks for your time. DeAnn
I changed the convergence board but the flash focus only gets to 37%. The blue will not work. I can at least watch the tv without it making me sick, but the words are still hard to read. Is there something else I can do?

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
