I had a customer come in with a Cu920 (Vu). She had gotten it wet. So i cleaned the MoBo along with everything else and was able to save the phone; all except for the phones ringer. The speaker works fine; you can hear conversations fine; however the ringer wont sound at all. I believe this is the Red and Blue Plug in part connected to a small circle silver part located next to the speaker, at the top of the phone, but I'm not 100% sure...anyone know if this is the ringer and where I can get a part. I cant find a repair manual for this phone either. I am currently on Ebay looking for a damaged phone. Thanx in advance.
