My TC-2489LCD TV goes thru the channel scan but can't load any channels even on a Known good aerial?

The TV signal is no good if it cannot find any channels. You will have to check the signal cable and its connections right back to the aerial. You may even need a better aerial or a signal booster. Digital TV needs the very best of all these or the picture just goes to porridge.
.

Then run it but ensure that the aerial is in a good condition and is correctly connected. Also...ensure the tv is set to the correct source....digital.
Hopefully this should find your channels. when scan is completed
Remember to save the channels

do you mean if you hooked up the tv with the aerial antenna can not get any channel? ok if just a white raster only and doesn't scan or tuned even manually and auto search, the cause is bad tuner.

Hi there,

You don't necessarily need anything else, but you may not have a strong enough signal to pick up the digital/freeview channels using an indoor aerial. It could also be that the indoor aerial is not correctly aligned.

If the signal strength is lower than approx. 50%, the TV may detect them during the automatic channel scan but it wont store them. When the signal strength for any digital channel is 50% or lower it's more or less unwatchable - the picture would be constantly breaking-up or freezing and the audio drops out continually. Trying to scan for channels using an indoor aerial is rather hit and miss. Numerous attempts may be necessary before you get any channels.

Assuming you have a roof aerial, it is far easier to temporarily connect the TV to a fixed aerial point while you run the automatic channel scan. The TV will store all the channels and you can then move it to it's permanent location and connect the indoor aerial. You can then adjust the indoor aerial with the channels already stored until you find a location for the aerial where you have a good signal.

Doing it this way also eliminates the possibility of a fault with the TV and confirms that you are performing the channel scan correctly. If the TV is connected to a fixed aerial point and you are still unable to receive or store any channels, then it's likely that you are performing the channel scan incorrectly or there is a fault with the TV.

Please try scanning your channels using a known working fixed aerial point. If you are still unable
to receive any channels - or you don't have any fixed aerial points - please post back for further assistance.

Hope this helps.

I would try scanning for channels when tv is hooked up to your house main aerial or a portable aerial. If it does pick up channels, the tv is not at fault but instead your aerial ontop of trailer. If this is the case, check your aerial plug. If the plug is moulded on it may be broken inside, or if it is a fixable plug, check that the outer coax shielding is not touching the centre core inside the plug.

was it working before ?
Are you on cable ? run your scan in cable mode
Are you on an Antenna run your scan in air mode
