Hi,
I had this exact problem, the problem gets worse with time... At least
mine did. I sent in my P3 to Elecraft repair, and got it back a month
or so later working...
73, and thanks,

Allen,
I have this issue with my P3, and it seems to be related to internal (to
the P3) power rail problems.
I have the SVGA adapter, and the external display always works, even if
the P3 display isn't.
After leaving the power on for a minute or less, I can quickly toggle
the power button on the P3, and then the internal dispaly comes up.
The theory is that during initial power on, the power rail comes up too
slowly to get a clean power-on reset to the internal display
controller. Note that the P3 has been working fine for me since I
purchased the kit about ten years ago. This is a recent issue, showing
up about a year ago, as far as I can tell.
Some suggestions have been to replace one or more power supply
capacitors assuming they've become flakey, or to plug the P3 power into
the station supply, instead of the 12VDC output on the back of the K3s
(assuming that the 12VDC output is weak or slow to rise during K3s power
on). I've not tried either of those solutions, preferring to just
mitigate the issue by toggling the power, which doesn't happen very
often, because I tend to leave the rig on most of the time.
Hope that helps, and 73,

Quoting n...@earthlink.net:
My P3 screen has gone black. When I plug in the power, I still hear some
very quiet relay click. Any quick ideas?
Full disclosure: I suffered a voltage spike some time ago which took
out my
K3 some time ago (it is at Elecraft now); P3 still operated but the POWER
switch no longer worked, i.e. it was on all the time whenever power was
applied. (I am borrowing a K3 from a very, very good friend).
Does anyone work on P3's besides Elecraft?
