Tektronix 475 sweep triger repair??

I have a older TEKTRONIX 475 Oscilloscope that needs repair, the sweep will not trigger either
channel 1 or 2, it auto sweeps fine. I have checked & re-plugged all connections possible with no
improvement.. Might anyone have any suggestions as to a potential. reasonable, cheep, repair,
recalibrating person in the central Michigan area? I have checked with Tektronix repair locations
in the north east USA but there minim prices are in the high hundreds just to check it out.

If you have repair experience yourself, you may want to search for the
service manual for the 475. I was able to locate on for my 2445B
scope. I have seen tehse on Ebay and Craigslist.

Also a post on the Yahoo Tek group would be very, very valuable.
