Kevin, If OSD works, you are looking in the wrong area...double check your work, perhaps you left a cable unplugged...easy to do on these babies. Perhaps you have a bad tuner...try the video inputs...should be your next step.

But now I have no video with tuner. Just a black screen and tuner audio. The OSD is working so that is how I know that the horizontal problem is fixed. The red, blue and green guns measure 200 volts each-they should measure about 150 volts so that is where my problem lies. The larger resistors and transistors on the neck circuit board are not even getting warm. The proper color signals are not getting to the picture tube. I have difficulty with this type of problem so any help would be appreciated. I have replaced Q2906, I have tested every transistor in the video, vertical, horizontal, and pincushion circuits (by measuring voltages and comparing them to the schematic), I have checked for shorted caps in the vertical circuit, the heater voltage is 5.9 volts, and the screen voltage is 300 volts. Either I have damaged something as I worked on the set, or the set had 2 problems. Is it possible for the video to be blank, and for the horizontal collapse to show a bright vertical line-both at the same time?
