If anybody has an R171 A50 they want to sell, I'm looking for one, working or not. I've found the fascia circuit board in this radio is located in the "drink spill zone", and I'm suspecting acidic action from a spill causes the lower circuit board etchings to corrode and break. The etchings in the lower portion of mine are more rough compared to the rest of the circuit board, and I can see visible damage to the etchings - including breaks. I'd like to try repairing it, but I don't want to practice on my unit (which is mostly working ok, excepting a few dead buttons).
