TV Repair Questions? Ask a TV Technician
Thanks for using this service
Welcome to JustAnswer
You need to get the set into "digital" receiving mode using the input button to toggle to digital reception then the antenna thats greyed out should appear,so in other words you shouldnt be in any other input AV1 or EXT1 etc only digital
Please let me know how you go here
HDMI and the antenna are entirely seperate inputs
Their wont be a channel set up feature in HDMI its an input for other kit
If you want to tune the channels in via the antenna you have to be in TV mode and as its digital only now digital mode assuming its digital built in I havent checked at Sharp as the site is down
Not HD channels no
Digital channels yes
There should be a toggle switch to go from digital to old analoue sometimes its the TV button sometimes its another marked DTV usually?
I dont have an operators manual for this set so Im struggling a bit, we are Sharp agents too!
