Question about Mitsubishi TS-5545 55" Rear Projection Television
Recently, groups of "cycling" black horizontal lines appear on the screen on all inputs. There is about a centimeter of space between each group of horizontal lines. The lines go from barely noticeable to obvious and back in a continuous cycle, and seem to move up the screen, then become momentarily stationary, move down the screen, and finally back up again. At first I thought it was some sort of outside interference, but now I believe it is some sort of "scanning" issue.
Sounds as if you have a bad capacitor in the horizontal deflection or video circuitry. You can spot a bad capacitor in circuit with a ESR meter.Hope this helps.
