I can converge in the center portion of the screen. But outer portions top, bottom, left and right form a pincushin. The curvature doesn't allow for convergence even though I can move the three colors. Please help
But there are two
quick things you might be able to do. If it is a PTK195 you can most
likely install the updated power supply board. If you can solder and
know safety (like discharging caps) you can update the PS chip from an
STK730-??? to an STK730-180 (IIRC). I found that simply replacing the
chip with an equivalent fails most of the time. The 180s seem to hold
up.

Picture is warped, in the center vertically it is smaller or concaved and on the ends it's larger like a sidewise hour glass. Like when on a computer, screen pincushion affect. Can this be fixed by adjusting a resistor or like adjusting a computer screen.
