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.

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 on by power cycling it as
well...
Hopefully someone has actually fixed this, and knows which cap...

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.
