Stephan
2/5

I ordered 2 and have tried both the fix documented by Chao and by Ricebelly - but without success. I continue to have a black strip right through the middle of the display - same as documented above.

Based on the last two reviews, this board still seems broken. Is there some fix not listed above that actually works ?
