I had a similar problem years ago. Apparently a not-close lightning bolt damaged the tx protection. Elecraft Tech Support was very good in the diagnosis and suggested I could do the repair but my skills are from the vacuum tube days so I sent it back to Elecraft for repair.
I suggest you contact Elecraft support.
