I had a similar problem with my P3 with SVGA. I had to cycle through the on-off switch a few times before it would fully power up. Once powered up, everything was working and stable. I tried reseating the ribbon cables but that had no effect.
I contacted Elecraft technical support and they had me try a few things but that did not solve the problem. I sent it to Elecraft and it turned out that the I/O board was faulty. The repair cost was approximately $200 for a new board and labor. 73 Howard/WX7HS > On Apr 12, 2021, at 06:05, Dave Cole <d...@nk7z.net> wrote: > > Rick, > > Thank you!
