Crumar Stratus/Trilogy Key Problem

Hello everybody!
I bought a Crumar Stratus 3 weeks ago, and the Price was pretty cheap (200€ with shipping included). It Works perfectly, except that depending on the voice I'm playing, some keys are not playing properly. For example: for the organ everything works except the G4, but for the synth only 7 Keys/Octave work….
The sound i get is great, and I really need to fix this, cannot wait to have it on 100% working
I tried to dissamble it, and everything is original, and never touched, (18 CEM chips included).
For the issue, I only can thing is somehing worng with some TDA's that are not getting the key signal out, and now comes my question :D
How can I acces to them???? the are over the keyboard, but really cannot move it out, does anyboday knows how can I do it? Did somebody have the same problem before?
Thanks! cannot wait for yout answers :)

Soooo! I´ve Managed to open the synth, and checked the TDA´s and all them are working, so have no idea were the problem is, will still be trying. Next step, to check all Capacitors.
If somebody have the same issue, please let me know, i´ve seen some old posts about this in internet, but don´t know if the problem was solved.
