need to fix broken door entry intercom?
Hi, my door intercom doesn't work properly.
My building has 3 entrances with seperate intercom panels.
From 2 of them when you dial my appartment number its says the line is 'busy', and nothing happens at the apartment end.
I've been told the handset in my appartment needs replacing. However, from the third an image appears of the person who's dialed, but thre is no sound and the door opening button doesn't function.
Unfortunalely I rent and have a landlord who's refusing to relace the set because of cost - so anything I could look to repair would be really helpful
thanks
