Question about Nokia 7370 Cellular Phone
Nokia 7373 will not ring, or nothing on loudspeaker or speakerphone.
During a call, the handset volume is 10 and works fine. Also works with bluetooth headset and wired headphones.
But if anytime during a call or playing music, and is switched to speakerphone, nothing comes out, even with volume at 10.
I've reset the phone *#7780# and also updated with v5.5 for this phone.
What else can I check?
How can I check the phone amp N2101? What voltages should be when speakerphone is on? What other test points can I check? How can I check the speakers?
This problem is not cause by the software. The buzzer of the phone must be replaced with a new one. Go to the nearest Nokia Service Center or any cellphone repair shops you have that one on your area, or from where you bought the phone. This buzzer is the audio output for music, tones, etc. except for the calls, its a different speaer.
Please Rate Thanks!
