Hi Mobes
None of the Sharp codes worked so had to go through the whole process that involves inputting 0999 in place of the code and pressing channel up until the TV turns off.
Don't just accept the first code that seems to work when using the 0999 method. Often they are only partial matches and continuing testing using 0999 results in a fuller match.
Enter the code 0999 to access the TV code database – the LED will flash green twice.
3. Press channel up until a code turns off the TV – the LED will flash green each time a code is sent.
4. When the TV turns off, release channel up and press standby on the remote to turn the TV back on.
5. Press vol +/- and mute to check that the remote is working with your TV. If they don’t, continue to search using channel up until the next code turns off the TV, and repeat steps 4 and 5.
6. When the Volume and Mute keys work, press OK to store the code. The LED will then flash green twice.
