I have just finished assembling this kit and there is nothing on the screen only the back ligthting work, the board seem to have to capacitors missing and crystal ocilatator but they are not mentioned ing the build instrusction, but they show up on the circuit diagram, can anyone help me with this delema?

Please excuse my bad spelling


Dear PeterKeller,

The Crystal X1, and the two capacitors C12,C13 must not be mounted.
see image of instructions in manual:

Also check if the diagonal bolts on the front panel are soldered,
see image below:

If this doesn’t solve the problem, I think it’s better to send it back to your local shop for repair.
