tuner problems with samsung LN40A650

by pravasi / October 24, 2009 12:20 PM PDT

Living in the city, we are pretty close to the TV stations, still the tuner cannot catch a single channel. Recently a friend bought an external antenna, and we tested it and could catch all signals. Even after removing the antenna, the channels were still available.

After a while, now the TV cannot tune any channels.

What is the use of buying a unit with a tuner if it cannot catch a single channel?
What is samsung doing to fix this problem?

I have other friends staying close to my residence who can catch digital HD signals.

Any response from Samsung guys before i recommend others to avoid samsung at all cost.

Irritated Samsung customer (and maybe soon to be a avoid-samsung-at-all-cost customer)

A common problem with this symptom is that the input was inadvertently switched from "Air" to "Cable", which would result in no channels being found. See if that helps.

If not, keep mep posted.

Yes, i know about the 'air' and 'cable' mode.
In fact, i had started the samsung rescan for both (read properly) BOTH the 'air' and 'cable' mode.
It obviously (Read OBVIOUSLY) found the channels provided from by cable company, however no air channels were detected.
When mode is switched to 'air' then it gets no channels, though when switched to 'cable', the ones provided by the cable company can be seen, and when switched back to 'air', no channels.
What i mean to say in short above, is that i am a techie and not an IDIOT or a lay person.

As already mentioned in my previous post, no air HD channels were detected.
As indicated by "", all the transmission towers are within 6 miles of my residence.

The point is that if the in-built tuner cannot catch signals being this close to the transmission towers, what use is the tuner for?
Why does samsung put them into the tv, and folks like us unnecessarily pay for the tuners when they are completely useless.

Thanks for any helpful tips in advance

If you do not have a antenna hooked up to your antenna input on the tv, then you will not receive a strong enough signal. The built in tuner only means that it takes an antenna connected in order to receive channels on OTA sources.
