Digital TV Reception Trouble Shooting Guide

Digital TV Reception Trouble Shooting Guide

After a channel scan, some channels or no channels are found

• Your TV antenna may not be properly connected to your digital receiver

1.Did you connect your antenna as illustrated on Page 7?

2.Is the antenna wall socket in good condition? For optimum and reliable contact performance, the antenna wall connector should be an ‘F’ (screw) type connector.

3.Are you using a quality antenna fly lead between antenna wall socket and iDTV? The use of RG6 or RG59 Quad Shield 75 ohm coaxial cable fly leads with metal ‘F’ connectors provides a secure, reliable connection that also greatly reduces impulse noise pickup. Low cost antenna fly leads with right-angled plastic molded connectors are a common cause of poor reception and impulse noise pickup.

•Digital TV or some channels (services) may not have yet commenced in your area.

Consult with your retailer who has local knowledge on DTV broadcasting

•The signal received may be too poor to allow the digital receiver to find some or all available channels or

•Your old antenna may not be designed to receive all DTV channels or

•Antenna reception performance has deteriorated due to weathering, corrosion of antenna connections / cabling and broken elements.

Please contact your local TV antenna installer.

Generally, a quality suburban antenna installation consists of: (1) separate VHF (Ch’s 6-12) and UHF (Ch’s 27-69) antenna’s (rule of thumb; larger antenna’s with more elements capture more signal). If you live within 5-10Km of DTV transmission towers, a combined VHF/UHF antenna should be adequate. Outside this area, separate VHF and UHF antennas provide superior reception performance.; (2) a shielded diplexer that combines the separate VHF and UHF antenna signals intoone signal. Depending on DTV signal conditions, some installations may instead require a VHF/UHF masthead amplifier. (3) RG6 Quad Shield 75 ohm coaxial cabling (4) ‘F’ connectors.These guidelines equally apply to regional installations except for the antenna, which, in most cases will be UHF only, since most DTV broadcasting is usually located in the UHF bands.

To avoid personal injury and property damage, qualified antenna installers must perform antenna installations, repairs and inspections.

The existing Master Antenna TV (MATV) system may have been originally designed for analog PAL TV only, and may require a substantial upgrade or replacement to also carry DTV signals. Please consult your Body Corporate.

•Received signal is ‘too weak’ (i.e.; poor quality) to generate a stable picture Please check antenna & cabling or contact your local TV antenna installer.
