If you you are looking for instructions on how to disassemble the Q900, here are some pictures provided by Nikolay (LZ1INP). 🙂
He got his Q900 delivered with no power output on VHF/UHF and found a broken patch cable with IPX connector.
There ist also a russian Youtube video with complete disassembly and close ups. You can use the auto subtitle translation from youtube:

As usual: please do it at your own risk and warranty will be void!
– red circles: the screws on the aluminum case, then on the top board
– yellow: ip connectors
– blue: ribbon cables
– purple: screws on the cover under the battery
This should be the correct order. Click on the pictures to open in full size.
Caution: the battery is taped with thin double sided tape. Peeling it off the metal base is done very, very slowly and carefully. Patience is needed. In the additional pictures you can see where the tape was located on the metal plate.
