If you are always needing to auto program the tuner then I suspect a faulty main board. Bring it back as it should be under a 30 day return policy..

Will not tune in channels on auto store


Well, there's your answer then. You have poor aerial signal so the TV cannot lock on when tuning. You need to sort out the reason why there's "Poor or No Signal" You need to fix the aerial, not the TV. I would have thought that was self-evident, surely?

What kind of aerial are you using. Do you know it works? Check out the aerial cables for breaks or badly fitted connector plugs.

Keep losing signal


You have a weak signal. There are many possible reasons for this, such as:

The aerial has moved or there is a poor connection.

You are tuned to the wrong transmitter.

Can I tune in my samsung 2-3 year old TV to an old non-digital VCR?


This would be easier to answer if you had included model numbers of both. Check the connectors on each and you should find color-coded connectors marked with matching inputs & outputs. You will need to connect the outputs of the VCR to the matching inputs of the TV. The signal coming from the VCR will, of course, be analog so you may need to set the TV on channel 3 or 4 and select the appropriate inputs of the TV via the main menu. It should state 'Analog.' If you are concerned about keeping stereo signals on the proper sides, red=right, white=left.

New LG 32LD350 - Allowed TV to auto-program channels, and for some reason, it skipped past channel 4 during the tuning process. When I select channel 4 in the tuning options, it comes up as no signal. On...


When you are auto tuning the system will not store a channel which is week by its standard ( at least 60% signal strength ) This done to avoid grainy picture and hissy sound.
You can go into manual tuning and store it.

Samsung lcd tv is saying low or weak signal when trying to tune it in


you can only use your tv to scan for channels with an antenna or if you have that tv hooked to cable television. use your Directv receiver to scan for channels, if you have an antenna hooked up to it. --------------- click this link for more help http://www.highdefforum.com/directv-forum/77638-new-lcd-tv-d-sd-no-weak-signal.html thaNKS.

Displays weak or no signal


To get any HDTV to work this is what you have to do;
CHANNEL section
1) Connect your antenna cable which you have done.
2) Go into the menu to the source option and select AIR/ANTENNA since you are using an antenna.
3) In the menu you will have to SCAN in the stations. This auto program will find all available stations.
Now you can watch tv by selecting the station you want.
The new generation of HDTV is different from the old analog sets. These have to be set up to work.
Exact information can be found in your Users Manual.

50 " Samsung Plasma TV


Get the tech supplier to tell to the manufacture and the store what he told you.

Physical damage on any electronic device is very hard to have serviced under warranty. I have never seen a plasma display crack on its own. But, anything can happen.

I once saw a man drop a newly bought plasma TV in a parking lot outside from where he bought it and the screen broke. He never even made it home from the store!

Maybe you should contact a lawyer or someone who can give you legal advice about how to proceed with this. In different countries and different states the consumer protection laws are different.
