My OP-1 wouldn’t go into boot mode, and TE told me it was probably the DSP board, and they would look at it for a fee since it was out of warranty. Now I can’t find the DSP board anywhere to do this repair. I then found out this was a common problem, a manufacturing defect. I wonder if there are enough people with these problems the EU 2 year warranty rule can be invoked, or a class-action suit of some sort. TE has basically left those who have these problems without an option to repair the TE manufacturing defect.
