I had a similar problem.
I purchased a P3 kit in 2015, assembled, and it worked well. The firmware as
received, was a rev behind. Trying to upgrade via the normal method, was
unable to accomplish. Trying to force an upgrade, was unsuccessful. Had to
return for warranty repair. The EEPROM
I do not. The repair invoice from Elecraft only indicated a faulty I/O board
which was replaced.

Do you know just what failed on the I/O board? Was it possibly due
to static discharge?
I tend to leave an antenna connected, except during active weather,
but curious if there is something sensitive in the P3 I/O area that
can fail easily from a surge, like the old RS-232 circuitry in
Thanks Howard, I'll call you later today...

Hi Dave New,
It does help, and thank you... Mine has come back to life as well,
(power cycling it), and I am worried about turning it off now as well...
I will get an RSA from Elecraft and send it in... I'll report back to
the list what they find, and how long it took to get repaired.

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
I've been experiencing intermittent failures of the internal
display, as well as loss of at least one setting (Track/Fix).
I've been leaving the K3s/P3 powered on continuously, but recently
started turning them off, to save some 'always on' energy while trying
to figure out why our house
Rick,
A further thought on this... Next time your P3 fails, can you try and
grab an image from it using the utility? I just thought of that, mine
will not grab an image, when it is failed, so it is probably not the
backlight on mine.

Rick,
Thank you! I appreciate the datapoint in this. I was just looking over
the schematic and came to the same conclusion... It looks like a
backlight problem to me as well... I tried to find a datasheet on teh
4538 IC that appears to control it, but alas, nope. I got mine to come
back
My P3 does the same thing. If i keep cycling power it eventually comes
on and works. I suspect there is a bad capacitor in the LCD backlight
power. I have not actually looking into it yet.

A bit more data:
1. The (3 utility can talk to it.
2. If I try and capture an image, it goes through the motions, but no
image is captured.
3. It accepts commands via a keyboard.
4. A load from the last config file did not correct things.
5. A full power off and on did not correct things.
