This was an Icom IC-7000 that wouldn't power up. You can press the power "on", and almost immediately hear a "click" from within. This is caused by the processor shutting the rig back down when certain voltage rails aren't properly detected. This is a very common problem with these as they age. Almost always caused by bad electrolytic capacitors. I've found this to be with C501 or C502 in the head unit, or both. The larger value caps are typically the culprits. Here is a link to a PDF written by another ham on the same topic. These aren't difficult to repair, should you run across one with this problem. I didn't take pics of the task, since the .PDF adequately documents it. The link to the pdf is:
