Sony TV-700U getting audio but no video

[matthewray2b]

I tested all the other channels and the current one worked the best still. I think I am going to reapply deoxit cuz I may have not done a good job the first time. I may also try using a different device for the input just for diagnostics' sake. Any other ideas? What's the "intermediate frequency section"?

On the best channel, does the picture change when you adjust the fine tuning control? If not, the control is possibly not engaging.

If by "fine tuning" you mean the Horizontal Frequency knob then yes, it is engaging. You can see it working in the video.
