Today I experienced smoke as well.
After inspection I noticed 2 burnouts on 1 module.
Other 3 modules are already working again...

SO - with this problematic one - any ideas how to make it work again?
Is there any way to make this module work without the burnout part/area?

How to fix this? Is it enough to get burnout parts replaced? (are they anything special or should I get them anywhere?)... Or are the nearby chips damaged too? Any recepie from anyone who went thru this before? Experience and ideas welcome!
