Hi
the up button is working as a home home button
interestingly it works properly on the home page..
it is not possible to use the pad to type or search
please help
If the problem is located in the Roku itself, a restart may fix it. If you have sufficient control via the remote you can restart via menu path starting at Roku home screen: Settings..System..System restart.
If you don't have sufficient remote control you can restart by unplugging from the power source then plugging back in after a few seconds.
If a restart doesn't fix it, the problem probably resides in the remote. All I can think of there is to remove the batteries for a few seconds then put them back in. If that doesn't get it, you probably will need to replace the remote.
