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.
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.
I looked at the manual for my Samsung 750 model.
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.

Re: No signal or weak signal
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.

It sounds that the start signal does not comes from its main digital board to its main power regulator board. There is nothing a user can do with this fault. It will be best to contact any service technician. If you wish to get some details, http://electronicshelponline.blogspot.com/ Pull up older posts.
This seems to be due to the TV being on the wrong input. Use your Vizio remote and cycle through the inputs until you reach the audio inputs. Try all of them with the receiver on and the amber,green and blue lights on the receiver. If you do not see a picture here the TV may have been connected by coax. To check this go to th TV input using your Vizio remote and key in 03 or 003. You should be able to see satellite now. It will also depend on how your system is a connected to your peripherals if you have any connected.
Hope this solves your issue. Thanks for using FixYa.com.
Left up the VCR tape gate,see,if the tape still in there?Yes,unplug,10 mins.replug the Tv and push the tape forward botton.Let the tape go forward about 5 sec. eject the tape take out.Grandson probally rewind the same seen to many times,causing power power shotdown mode.
Try holding the hand held remote up next to the homelink (built in remote). Hold down the botton on the hand held remote and the botton you want to program in the car at the same time until the homelink light goes out. This could take 60 seconds or more. Now depending on which model garage door open and how old it is you may need to program the car to the opener. Usually this is done by pushing the botton on the back(Liftmaster,Sears, Chamberlin) or the botton on the front(Genie) and then go to the car and push the same botton on more time. I hope this helps.
Usually one connects a RF [cable tv, Dish tv, antenna ] cable to the INPUT of VCR & a RF cable output to tv (antenna )INPUT .The reason is that if you are watching TV reception (Cable, Dish, etc) and you want to watch VCR tape, just push the tape in and it should start playing picture. From what I understand that you are trying to say:: [ YOUR NEW TV ! ] you MUST connect to the RCA jacks, CABLE S with RCA plugs that come out of the VCR to the new TV [ INPUT & OUTPUT] jacks .When you ["" use input botton on VCR remote"" ] you are using a DIFFERENT input signal. You are not letting the TV know that you are changing the signal from RF(antenna, Cable, Dish,etc)to the RCA signal ["" I use my input botton on my vcr remote""]
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.
