Compare IC connections with meter = check solder joints to
see if some are touching one another. Tell me exactly what
brand & part number was installed...........T.
PS. The red,green,blue plugs may be mixed up because the green should stay and red & blue move !

Convergence problems

Did you buy the board new or used? It could also be your convergence Ics and not the convergence that is causing the shutdown . The convergence ICs are not located on the convergence Board.

Samsung HCL5515W red convergence problem

sounds like your convergence IC's have fail and possibly a bad dcm. Some of there models have a small board with the ic's them. It may be cheaper to replace the board. But you can repair it if you have proper equipment

My samsung rear projectiontv is showing in 3d

Hi, your convergence circuit has failed, the stk`s and any burnt resistors will have to be changed, if you know how to solder and un-solder proficiently and can use a volt meter it`s do-able if you don`t have this knowledge call a tv tech, generally runs $250 to $350 depending on where you live, call around and ask for estimates to fix the "convergence circuit", if you still have questions e-mail me back, Happy New Year, BMW Rider
