My Sylvania television is a little older but it won't stop trying to scan for Dtv. It just has a black screen that will say now scanning.....
Have Sylvania CR202SL8 TV with same problem. Cannot stop the scan or reset TV. It turns off at 15 minutes as designed when no action or signal.
DId you ever find a solution?
It had been in storage for years. Inititally, on power on it turned off on its own. Let it rest and retried and went in to Menu, I scanned the channels on antenna and worked fine for 15 minutes. Showed Now Scanning for seconds but image came back. Then it went into the Now Scanning screen and got stuck.
It did once get to the menu (don't know if on its own or my trying remote control button combinations) and was able to restart the scan (DTV/TV option, don't have DTV only option)...apparently it scanned digital, but started scanning for on air channels and got stuck on Now Scanning.
SOURCE: will not scan for wi fi
Make sure your wifi card is enabled. Most laptops have a switch or function key that will turn the card on or off. If it's active, make sure you have the drivers installed. If you bought your laptop used or just had your OS reinstalled, the drivers may not come with it and will need to be downloaded from Sylvania's website from a computer with a working internet connection.
