great guide! how can I repair a VarioUltra 20? are the procedures similar? the device has a problem at point 4 of the sixth cell, the point moves unsteadily, should I replace this whole cell or is it possible to just repair point 4, which is defective?
which professional will likely be able to repair a braille display? should I look for an electrical engineer or other professional? I'm blind, I don't repair electronics, but I have a defective braille display that needs to be repaired. I live in a country where there are no companies capable of repairing this product. I do not know what to think. sending the product to a specialized company in another country is very expensive for me.
