First the MP 1 got modded, the MP2 can wait, first collect the needed IC's.
And hopefully it will work.
Maybe the LCD don't need to replaced.
Hope Marshall JPM can help me out then.
Tomorrow i will send the MP1 to him.

No worries, Danny! MJMP will get it working again or at least have an assessment for you to consider. You're in good hands :thumb-up:
