Question about Samsung LN-T4061F 40 in. LCD HDTV

No signal or weak signal

By cstewart5000, posted on Sep 21, 2008 My grandson pushed a botton on our remote. My husband tried to fix it. I can not get a picture at all now. I get the error message no signal or weak signal. Is there a way to reset the tv and let it reload? I've unplugged it and disconnected the cable over night thinking it would let me set it up again.

  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 displayed as strong. Disconnecting did no good. I surmised that the box was simply not recognizing the TV.
  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 husband will be so proud of me when he returns from hunting camp.

Sorry I see the model,
hold the Menu button on the TV (not on the remote) down for three seconds.
Note: Shop Mode is activated in the same manner: Pressing and holding the Menu button on your TV for three seconds. To avoid accidentally setting your TV to Shop Mode, avoid pressing and holding the Menu button on the TV for three seconds or more.

The remote does not work the TV have put in new batteries


Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Pull up older posts. If the remote control is found OK; check and replace the infra-red sensor inside the TV. Contact any service technician.

The remote has stopped working so the only way I can change channels is on the actual tv


Easy way to test an infrared remote is to point your camera at it and then push a button on the remote and look for the purple color on the camera, If you don't see the color AND the batteries in the remote are new AND installed correctly, it is time for a new remote.

Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. In some cases, the remote control might need to clean.
