Hi and welcome to FixYa,

To get a good signal on all TV units, the source must be good and strong. The source could be an aerial antenna or connection to your local cable provider. The message "No Signal" indicates that the TV cold not receive a decent TV signal. With this in mind, possible solution wouold then be to increase/improve the incoming TV signal:

  • if you are using an aerial, 'height is might' to overcome any line-of-sight obstruction. Additionally, there are antennas with higher gain, meaning they could receive better than other antennas. Another option is installing a pre-amp or commonly called booster;
  • if you are hooked to a cable provider then it may be to your advantage to bring this concern to their attention. They could try transferring you tap off point to a better distribution box, replace your coaxial cable with low loss or even in some cases, install an inline booster;
  • possible RFI (radio frequency interference) which could come from wireless phones, garage door openers, WiFi, electronic dimmers, electronic ballasts of high density lamps and others. If any are present or within the immediate vicinity, pls try to relocate or reposition.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

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.

No, not really but you need to know specific information to make sure the one you get is compatible. If you're good with electronics you should be ok doing it yourself but this seems like a good deal:

Samsung 50 inch plasma tv screen goes blank temporarily


This could be caused by a loss of video signal either from the connection or from the source. The TV may have detected an error which caused the screen to go blank. If this occurs again, check the cable connections and see if having the TV unplugged overnight resets the TV and eliminates the problem.

Screen frozen


Un plug the power to the Plasma Screen and also to the Media Receiver for ten minutes. Disconnect the off the air antennas both A and B. After ten minutes plug in the plasma screen then the media receiver and turn on wi the remote control. You should now be back in operation. I was.
Also It may not be a bad digital tuner. The TV Guide feature is active even when the zip code is set to all 0s so if you have an over the air antenna attached the TV will look for the TV Guide info and if it can not find it because of a weak signal or the chanel it is tuned to does not carry that information the TV thinks that tuner does not work which triggers the 12 flashes. Also on power up the gray box with the waring message "Plasma Display Starting Up, Please Wait" appears and the screen is blank.

If you mean the picture froze or formed fuzzy pixelated picture and crackling, this will be due to a poor aerial signal to the tv, but if you mean the screen rolls with pink/white patchwork type squares and shows the picture in the background, all be it fuzzy, then that's the same fault as I am getting and have had to report the fault to LG as I am on my second TV. If it is the problem mentioned in the first sentence, it is happening to our friends in OS and they have been told by specialist aerial fitters, the signal is too weak for the tv.
