I'd just like to have an idea of what the problem might be before I
change any more components. Now I'm half wondering if it's the IC and
the fact that it's facing up and has a fan on it is allowing it to
work properly. Anyway, thanks for reading my long story and I'd
appreciate any suggestions you have.

This is where I downloaded the service manual:

The problem is you bought the scope without the manual that should
accompany it as it travels through life. I lucked out and got my $225
465 from a Tek sales rep/ham. The 2" thick manual includes all repairs,
upgrades, part substitutions, liner notes, etc. In a perfect world the
manual travels with the device.


In the real world, it is a pain in the ass to carry yet another item
you don't need. Just about any manual for a Tek scope is available in
..pdf format. Burn them to a disk or a USB stick and carry them that
way.

I have almost a dozen Tek scopes, and only have about a half dozen
paper manuals. I can print out the pages I need from a PDF, and if it's
searchable I can export the parts list into a text file to make notes on
without worrying about messing up a paper manual.
