Question about Samsung PCL545R 54" Rear Projection Television

1 Answer

Ghosting and distortion

Ghosting of color blue. Gradually getting worse and now horizontal lines have radical curve in them.  Research points me toward the “convergence board”.  Whatever that is!  I am fairly handy and don’t mind digging into it if I had more direction.  

Such as:

          Where would I by the parts?

          What does the board look like?

          Which one is the convergence board?
What do you think?

    I have the same exact problem as the one described. The colors are fading a bit and that blue horizontal box with the lines bending you described is what I have as well.

You can buy just about anything you want on-line by searching.
 The convergence amplifiers are large, 2 inch x 3 inch IC's that
 are mounted on the largest heatsink(s) in your tv.Some Samsungs mount the convergence amp board up high,above the
main chassis (easy pull) or down low on main chassis.The part
number is Stk392-040.Change both for reliability.I use panasonic
brand  = never had a call-back failure yet.Reset alignment after
changing IC's. ..........T.
