My rotak is just trying to start ( when i press the switch is makes a clicking noise) but is not starting! And the blade is moving just 2 seconds then is stops ! Is can be from that Board as well ?
No, that's a battery-socket problem. Remove main cover (4 Torx T15 screws) and in the front replace the tiny spring (Bosch item number: F 016 L66 108.). When the spring gets worn out the vibration of the machine shakes out the battery from its place in 2 seconds. Try holding the battery firmly in place and if the machine doesn't stop then it's definitely the spring.
