Does it go one octave up relatively to the actual setting?
Or does it go up like you would set the synth to "transpose up"?
Or does ot go much over the the standard 1 oct. up value?

If it is only like 1 octave up, then I would check/resolder the solder 
joints of the complete transposition section of the voice card (around 
TR1-4, FET1-4, IC7, TR5).

If it goes up much more than the standard maximum, then more assumingly 
some supply power or some ground is missing around the VCO circuit.
