NO sound and cable signals

If using a cable box then you want to set the TV to channel 3 or 4 as the cable box will output to one of those. If no cable box then its possible the TV's tuner is bad or your cable company only transmits in digital form requiring a cable box since this TV only has an analog tuner

Hi,

Did you try setting and finding the other missing channels manually?

You need to go into on screen TV tuner/channel scanning setup page and change the signal source from CABLE to ANTENNA so it will scan again to pick up off the air signals. Please read the TV user manual for more details.
What is the model number of the TV?

To get HD channel form your cable TV without using the cable provider HD tuner box but using your TV Clear QAM tuner (your TV has Clear QAM tuner, my TV also has QAM tuner so I do not have to use the cabel box, but my COMCAST does not provide may Clear QAM signals like they use to) to get the unscrambled HD, the cable provider must provide those unscrambled Clear QAMsignals for your TV to pick up the signalS.

Did you use the correct setup during the tuner setup to scan the availabel cable channel per user manual?

If you are receiving the signal from the same cable service provider rather than through an antenna, I would suspect the cable service is having a problem with its retransmission of the ABC channel in that suburb. I don't know if Australia is still broadcasting analog TV signals or if ABC is digital, but if the latter, perhaps the receivers are having trouble decoding the sound format identifier information. This could be something as subtle as a timing tolerance issue or as crude as noise or low signal level on the cable that has the receivers operating at the margin of sensitivity.

if the display says cable, it won't get over the air signal. switch the source to antenna, hook up an antenna and go through auto program sequence.

Before you bought your new TV, was the cable connected to an older TV, and was it working?
When you say you screwed the cable connection to the antenna input, did the cable come directly from the wall, or did it go through a cable box first. If it came through the wall without a cable box, it's possible it's not an active cable account, and you're only getting over the air signals for your local channels (and nothing through the cable). Or, your cable signal might have been analog only, and with the transition this week to digital TV, maybe you're no longer getting the channels broadcast properly.
If you are a cable subscriber, then this problem should be reported to the cable company, and they can do further testing to see what's wrong with your signal.

Bob,

Are you certain you've connectet the antenna coaxial cable correctly?

There's 2 of them on this TV, one for digital and one for analog/cable connections, make sure you're connected to the correct input for digital TV.

If you're certain you've got it connected correctly then your problem is going to most likely be in the TV tuner board inside the TV.

Good Luck!

Is your tv connected to your cable box through HDMI, AV, or component?
_____________________________

If its through HDMI then your cable carrier needs to load updated frimware in your box to communicate properly with your 2005 tv. The firmware loaded in your cable box needs to be "reverse compatible" for first generation HDMI from your 2005 tv. If your using AV or component hook-up and there's no sound then re-check all of your audio settings within the tv's menu. Also recheck the cable-wire your using and proper input/output ports.



ON your dvd player, is your tv connected through component, AV(rca) or HDMI?

If its through "component" then you need an extra audio cable to and from the DVD and tv.

This is caused by one thing, poor signal strength.
