[1000mp] 1000mp lost power

[Steve]

 I just lost most of the output from my 1000mp MkV. 
The power output is about 10 watts on all bands.
The receiver section seems to work correctly.
 
 I Disconnected all the accessories, did a full 
reset and connected up a dummy load using a short, 
known good cable. Still low output.

 It looks like it'll have to take a trip to the
service center but I thought I'd see if anyone has
any ideas before I put it in the box.
