remote controls on tvs that buttons dont work on

Solution
If you mean will a universal remote work if the buttons on the original remote don't, it depends. If none of them work then the remote or the IR receiver in the TV may be bad. If the remote is bad then a universal will work if it has the correct codes in it but not if the IR receiver is at fault. If some of the buttons on the original remote work then the universal should work since that shows the remote to be at fault.
If you mean will a universal remote work if the buttons on the TV itself don't work. Maybe. You would have to try it to tell for sure.
