Pioneer Projection TV - Sine wave red convergence line.
I just inherited at Pioneer PTV. When I turn it on, the TV has bright
red short horizontal lines at some fixed regions on the screen.However The picture color appears fine and reasonably balanced. When I try to set the convergence, the red, blue and green lines are aligned with an additional curved red horizontal line (in the form of a sine wave - not curved) running parallel to the convergence line. Is the red tube going. if not can someone point me to which circuit is the problem. Thanks in advance |
