Facing TV Problems? Ask a TV Technician.
Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
Can you tell me the model of the remote that you do have?
Okay there is no scan button on it of course, but you can do this from the menu.
First use the input button to set the sharp to the TV (not video, hdmi, etc) input mode.
Then, press the Menu button to go into the sharp settings, under the Channel section of the menu, and there you should find auto program/scan, to search for the channels and tune them in.
Well in the channel section, you should have an option to choose analog or digital, when scanning, do you see that choice?
Thank you for checking, that means it is finding them automatically.
But you are still able to run the auto tune from the menu, correct? If so, and it just isn't picking anything up, that is either a limitation of this old tuner no longer being compatible with the current broadcast, most of which are mpeg4 format now, or that the internal digital tuner has failed.
In either case, there is no practical fix for it, repairs would cost more than a new tv.
Other than replacing the tv, your next best option would be to hook up an external tuner instead. You can pick one up for $50 or less at dick smith, harvey norman, etc. Example: https://www.jbhifi.com.au/tv-home-entertainment/players-recorders/teac/teac-hdb850-hd-set-top-box/87484/
