If it's a managed apartment block, could you speak to the administration? Even with no Spanish say Carblay (Cable in phonetic Spanish) & then run your finger across your throat. I'm sure they'll understand. I think the problem with asking for that sort of help on this board is that only a qualified electrician/Cable repair person would volunteer to submit themselves to liability issues if they attempted to help & it all blew up. Or worse, ruined everyone's else's Cable in the block. :ermm:
If the 'Carblay' & gesture gets misinterpreted as a request for cable with which to hang yourself...................find a Spanish speaking friend to assist.
