Hello there,
Quoting my yesterday's installation of ADTV HD, there was a problem in sending the cable down the cable hole. If the support was that bad, he wouldn't have stayed for 2 long hours and tried. He could have simply said call an electrician and fix it.
Thats exactly what happened with ucn .
Technician said get a electrician and he will pass the cable through that hole in the wall and left the cable through window so we cant close window now. Its open for 2 years now. Hope adtv technician makes use of that hole.
