[Elecraft] K2 - No Display troubleshooting

[Philippe]

Hello All,

I did the first part of the mounting and I'm at the stage of Alignment
and Test, Part I and yes, I'm almready stuck :-)

Turn on the K2, I ear the relays moving but nothing on the LCD. I did
all the checks according to the troubleshooting guide and as I did not
find anything wrong I came back to the Front Panel resistance checks.

All values are in range except for U1 pin1 where I find more than 1Mohm
instead of a value between 25-35K as stated in the check list.

I checked U1 for bad solder or bad pin insertion but it seems Ok on this
side also.

If someone can point me somewhere I can find help or a way to go
further...

73,
Philippe

PS : I ckecked according to the troubleshooting guide that :

000 = OK
050 = OK
060 = OK
075 = OK (i do not ear the 4Mhz oscillator but hecked with a scope and I
have an oscillation there)
