Back to the VT-71H

[Chris K]

I changed the sweep mica caps and checked them. They were all open. I replaced them with the correct size and voltage new mica replacements. The control pots on the back were all cleaned out with CRC contact cleaner but I did it again for good measure. Tubes checked again...all good and I cleaned the tube pin sockets with a mini-wire brush I got. Rechecked the antenna connections and went through all the solder joints and connections in the sweep circuits and IF. No change on the TV. Still no picture getting through. Audio yes but no video. Might be time to put this back up on the shelf for a while.
