Question about NexxTech 4318570 Corded Phone
I have to repair for a phone collector a specific vintage phone replica from RadioShach (InterTan) catalog number: 43-8978. It is a replica of a 50's black phone with a dial on front. Presumably, the model (molds and dies) was owned by the Paramount Comunications Company. The old fashioned dial has round touch tone buttons instead a classic rotative dial that functions likely any normal today's touchtone phone. The problem: - The phone rings correctly but when we take the handset, the person who called us cannot be heard from us and it seems to be the same thing for the caller. The caller cannot hear us. A very weak sound can be heard but neither the caller and the receiver can't talk mutually. - When we dial a number, the green DEL's who light on normally once the handset taken in hand, short down and nothing goes on! Also when dialing a number, No tone can be heard we hear only a "TAK" once the dial button pushed and the green DEL's shot down each time! The "PULSE/TONE" switch is settled to "TONE" and the "RINGER" switch is settled to "ON". Where I can get informations, PDF's to repair vintage phone replicas (normal touchtone phones) whatever the brand? Did someone on this forum can help me to find the problem? Thanks! Lhupa
Hi,
It is hard to diagnose an issue without having the phone in front of me. It can be namy things. These are probably made in CHina or overseas using cheap components.
What I would first suspect, is frayed wires inside the coiled cord. You can't see them broken, because they are covered up. It sould be the switch where the ophone hangs up. Many components are hot glued in place, dumb idea.
If you can hear the other person even parely it shows that there is an issue with a good connection. Over time, wires flex, and can break inside the cord. Switches might get out of place, get loose due to the hot glue coming off. Switches can also get dirty and must have contact cleanier sprayed inside the switch.
What I can suggest, is that you make a call, then when listening, wiggle the whole coiled cord wire back and forth, up and down, all directions. IF there is a momentary time when you can hear loudly, then you have found your problem. If the phone was in front of me, I could make some tests, but it is impossible to diagnose over the internet.
There may be a member of an antique telephone collectors forum around your area. I know the phone is not antique, but they will have the ability to test the phone locally.
Good lcuk.
