I just went through this with my Orion 1. Initially, the display was a
little dark in the upper left corner. Then, the display pulsed/flickered
and the radio never came on: the display simply pulsed/flickered.
I changed C6/C7 on the DC distribution board but that did not correct the
problem. Then, I noticed that C9 was slightly bulging at the top; replaced
that ( $1.29 at Radio Shack) and the problem was corrected. Cheap fix.
Warning: removing any of the electrolytics on this board is a challenge.
