Hi I've got a sharp lc 32dh57e TV but avent got remote could I tune the TV with a universal remote

Yes, it depends on the universal remote though. You'll need to find one that lists Sharp as an accepted brand on the back. Then you will need to test out the different codes listed in the manual. You may not get all the commands you need, but you should get the basics like volume, power, mute, and channels.

If you're looking for all the commands, you should order a new remote from Sharp.
