[Elecraft] KPA-500 Loss of Front Panel LED's

[Dave Gynn]

I wonder if anyone has a quick answer to the following problem.

Switched on this morning but no LED¹s light up on Front Panel, however the
LCD shows correctly with KPA500 and then PWR 0.  With a drive applied
amplifier shows output on the LCD.

Appears to have lost the power to the Front Panel LED¹s only.

Grateful for any suggestions to save sending back to suppliers.
