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.

Please can anyone help i cant tune my tv it wont pick up any channels when i auto tune it it says weak or no signal but i plugged aerial and tuned another tv and its fine


Are you trying to get over the air channels? IF you are does your TV have the digital tuner on analog? TV went digital and if you have an analog tuner will need either e new TV or converter box.

How to resolve TV tuning issues?


Check the orientation of the antenna. Try to rotate it, and see whether the signal strength varies. If the signal strength is too weak, digital channels will show many problems. Try a signal booster. Contact any service technician. http://electronicshelponline.blogspot.com/

Unable to set TV channels on Samsung LED TV


Check the orientation of the antenna. If the transmitter you're trying to tune is very far away from your home, the signals will be very weak, that the tuner inside the TV can't catch. If this is the case, the orientation of the antenna is very important.

Tuning VCR into Tv


Set the LCD to TV source and tune the LCD TV channel to 3 or 4.

For best viewing experience, you should connect the LCD TV to the VCR using component / SVideo or RCA cables instead of RF coxial to avoid signal loss. Your VCR manual should indicate these types of connections.

Weak or no signal message


  1. Since my problem (Samsung/Comcast) began with a channel selection button pushed on the TV remote when it should have been pushed on the cable remote, I figured the problem lay with the TV.  Although I was getting the "weak or no signal" msg., the actual signal strength bar graphic showed it to be strong. Disconnecting did no good. I surmised that the TV was simply not recognizing the box.
  2. I looked at the manual for my Samsung 750 model. 
  3. Page 20 discussed "Selecting the source". I accessed the TV menu and selected "Input", then chose the "HD..." item from the highlighted list. Voila! My tv works again.
