RE: ICOM A2 ori all LEDs red
Before changing or warming, you need to check such important components as power and quartz.

Never seen a broken quartz until now. But yes, maybe pick the oszi and check the basics. Thought, maybe there are some common problems  Reheating is most probably an clone issue - isn‘t it?

RE: ICOM A2 ori all LEDs red
Often the flux residues under quartz affect the work after some time. There are cases when mega16 is poorly soldered, but this is manifested in the first days of work.
