[TenTec] Orion sub receiver getting no signals

[Carl Moreschi]

Denton,

I think you have cable connections that need cleaning.  There's a lot of 
connections behind the Orion front panel.  It's easy to remove that 
panel.  Remove it and disconnect all the ribbon cables.  Spray them with 
a electronic cleaner spray.  Then plug them in and out about 10 times 
while they are wet to clean them.

This is a common problem because the Orion did not use gold pins.  And 
almost any symptom is possible.  The key is the problems are always 
somewhat intermittent.
