I recently picked up a ColecoVision, it works fine, but the picture exhibits some vertical bands in the color fill areas. You can see it in the green in the upper photo and the blue and red in the middle photo. The bottom photo is from a second unit using the same power supply, tv, and RF cable, which looks great. The PSU from the second unit was tried with the problem unit and nothing changed. I replaced the Radio Shack switch shown in this article with no improvement. I installed an RCA video out from this guy and, if anything, the bands are more prominent. Any idears on how to correct this would be appreciated.
