Question about Samsung HCN4226W 42" Rear Projection HDTV-Ready Television
It's probably convergence. Take the back off and locate the convergence board. On this unit it's up and to the left looking into the back of the unit - the board is on a separate heat sink mounted to a cross rail. Locate the two wire plug going into that board that is marked on the board +/-20v and unplug it. Now plug the Tv back in and try to power it up. If it comes up with good audio that board needs to be repaired. The two amps on it need to be replaced and both the return and line resistors out front of those amps need to be tested and replaced as needed.
My shop charges $225.00 to rebuild this board which should give you some idea about what you would pay..
Hope this helps!
