[Elecraft] LCD Problems

[Fabs]

Hello,

I'm from french part of Switzerland so sorry for my english :) I have 
some problems with the LCD from the K2. I have set up the control board, 
front panel et some stuffs froms de RF boards and when I plug the K2 the 
relays are inizialised, I have de back light on the LCD but nothing 
appears on it. I read the troubleshooting but I think that all is ok.

Have you some ideas ?

Tnx Fabs
