Probably an unusual question, but I need a bit of help with hardware of VVX500
I have one here with faulty hook switch and tracked it down to a faulty optical sensor that detects hook switch. It is in board position U202.
Would anyone know the part number of this sensor so I can order one? Feels like a waste to throw away otherwise perfectly good phone.
P.S. I am an experienced technician, so doing it myself. It is not worth to get someone (e.q. Polycom service agent) to repair the phone as it would be cheaper to source a new or second hand one.
