Sometimes it's just he battery itself that has died and the memory has corrupted. Before you begin removing more and more parts, an early test would be to just create a new clean patch (after and a new battery install) and save it. See if it remains as expected. It at least gives you an audible result. It's nothing definitive but it will provide some easy hints.

Thanks!
I tell to check transistors today.So i need create my own patch from front panel of synt?
Another thing that not all of the keys working, most of them not. I have cleaned them but result is same.I gave my synt to one good physicist but he is not musician so he need more information to test synt.Maybe i should take it back and record video with synt sounds and post it here to understand whats going on with it?
