Hi, It is good news to "hear" that You found the problem. This control board has also broken for us once but we had a broken camera unit from where we took this board as a replacement. Unfortunately I was not able to find the circuit diagram (among a lot of missing things). It should be somewhere, but last winter we had a major re-organization at our PCBA production area because our "suits" decided that it would be much better with this new solution. They totally misunderstand the "Lean Production concept". Haha yet another failure when they make fast decision and actions accordingly, without thinking and really don't understand how the production works... Slowly we are getting there to have the "Lean production" to work. I will give "the circuit diagram search" another try when I got the time. I will notify You if I am successful.
BTW. we also tried to put some very thin and narrow transparent sticky tape around the edge of the protecting glass and the Led:s to prevent chip components to fall between. Important thing of this is: It must not block any of the light from the LED:s. /Sincerly Ps. I am sorry for my poor english & grammar. Ds.
