Power increasing  with frequency suggests a reactive component has been damaged in the RF amplifier section.

I am assuming your ALC is not showing unusual activity on the lower bands?  Otherwise, carefully inspect
the RF amplifier board for any visible damage to chip caps or other surface mounted parts.  I am not familiar with the 590 design, but that is how I would proceed for starters.
