Question about Toshiba 50HX81 50" Rear Projection Television
Thank you for your help. I did find a burnt resistor. I replaced that resitor and now instead of the left (facing the front of the TV) end of my blue line curving downward it is curving upward and seems to be somewhat squiggly at the end. The blue line can be moved in all directions now and have tried the 9 point convergence adjustment and still cannot get rid of the curved blue line. I have checked the rest of the resistors on the convergence circuit board and all seem to be in the proper range. I even tried to move the rings on the Blue Gun.....still have the curve.... Is it possible that it messed up one of the IC's when powered up with the open resistor? How would one determine that? Since the Green, Red, and Blue connectors are the same, would it be possible to swap the connectors at the circuit board to isolate a possible bad Gun??? Would any of these tests or questions be covered in the Service Manual? Thanks again for any and all help.
