[Mainboard exchange on UM3]

Hi, 

Yesterday I bought a used Ultimaker 3 extended. As the seller wanted to show me the Printer, he accidently but in the power upside down. The Mainboard was damaged. Anyhow I bought the printer (for a reduced price) 
 

Some parts near the power switch burned. At least the Q4 = its4200s-me-n an some other parts - Multifuse F1.  Maybe also Q5 

 

As it look changing the board will be the fastest way. If I buy an Board (about € 250),  I read, that I have  to install the firmware and do some settings.

 

=> Where can I find the files and the description what to do?

=> Does a company sell a preconfigured MB? (can I order from Ultimaker or an UM-reseller) 

=> What I have to take care?

 

=> Any chance to repair the board? The parts may cost € 10
And  yes, I have the electronic double zero = license to drill (In Deutsch: Die Lizenz zum Löten) 

 

Thanks

When UM 2+ext ist selected i cannot chage the temperature as the menue doesn't show any values. When I select instead an UM (1) or UM 3 Ican change all temperature settings. Is this a Bug?
