I am happy to replace a dead LCD or dead DDS or dead chip.?
BUT, I have to note here, that in the majority of cases where someone believes they have a dead component, it is usually something else wrong. A poor connection somewhere, poor power supply, poor something. I find when I build something, I am unconsciously remarkably unwilling to give much weight to the idea that I might have made a mistake. Usually the problem is something *I* did, not something wrong with a component!
So all I'm saying is - be really sure - then as a last resort, I can send you some replacement part!

Could be the atmega chip that is dead. I blew up one of mine by applying too much voltage through a stupid blunder. The main sign that something was wrong was that the LCD was blank. i could hear activity on the HF RX from the DDS at 20mhz and at 125 mhz on a VHF multimode rx.
I thought the LCD might be dead but when I plugged in a new atmega chip from Hans, the whole thing came back to life.

Ok, Had some time to check my soldering which is fine, but lcd is dead.
Its now running to check if the DDS is alive as I will hear the tones on hf breaking through.
