The remedy in this case is tweaking the contrast.

Ok, that problem was solved. Now my problem is the vu meters.

You need to check the PCB for shorts. Maybe post a picture of it, I cannot determine the type of your board from the picture above.

If the Analogue board is not connected and you still see activity on the inputs then the most likely causes are:
1. incorrect values of R1, R4, R5, R6, R26-28 on the ADC inputs or the resistors being not properly soldered.
2. short/breaks on the ADC inputs (pins 34 - 40 of Atmega).
3. flux leftovers.
