I talked to the tadao tech and he sayd that the board canīt be repaired because the oled screen isnīt in production anymore...
Iīts sad when you trust in a brand with sutch a name and reputation and this is the solution they give you for a board that was on sale not to long ago for 180$.
For what i could find, mine isnīt the only with this problem, i have many friends that had the same problems with theirs witch takes me to a conclusion!
If you want a god board forget about Tadao and go for VIRTUE!!!!!
