Yes, it seems so. Corrupted file chain (especially in independent memory port) can cause a delay. It happened to me with an EPROM module, which appears to the HP-71B as a corrupted CAT chain. Turn-on was delayed by several seconds, but I don't remember any effect related to short or long off time, like you.
You could check if you have independent RAM ports (SHOW PORT), and clear them (CLAIM PORT).
Last chance will be a global memory clear.
