If the intensity control doesn?t work the blanking problem is a consequence of it.
With a high degree of probability one or more diodes of the intensity DC restorer are leaky. Since testing it is quite difficult, I would replace all.
This problem happens in several Tek models and also in scopes of other makers (Who copied the circuits designed by Tek).

Interesting that you mention intensity. The intensity adjustment does nothing. I am troubleshooting that now.
