[Elecraft] KPA500 Blank Display

[Lyn Norstad]

Bruce -

I've never experienced that with my KPA500, but it sounds like it might be
either a bad ribbon connector, or a bad component on the front panel circuit
board.  Did you assemble it, or was it factory built?

I suggest you talk to Elecraft service.

I'm curious if any others have seen this...................

Yesterday I turned on the amp and only the bottom half of the text was
shown on the display.
This slowly faded away leaving just the backlight on,    The band switches
were inoperable as
well.   All else worked correctly.

After 20 minutes the display suddenly came back to life and all was well.

After sitting all night the same thing occurred  this morning.......blank
display,  et al.   Several
minutes later it was ok.

Any clues?   NOTE:  This is a NEW amp 1 week old.
