Open the battery compartment and remove the batteries from the remote. Unplug the power from your Roku device and wait approximately 5 seconds, then reconnect the power cable. Once the Roku logo appears on the home screen, reinsert the batteries in the remote

gee did it ever work before or just found a used ROKU in a garage sale>?
NO system stated, at all, what do you have connected before you, (endless possible for sure)
so I will do wild guessing,
I first guess you have old TV that is not SMART, so no Netflix player s there.
so you buy a ROKU, (I have 2 love them, more on that later)
is this a new RUKU or old.? if old you need to upgrade the firmware on it per your manual,
The ROKU news version self upgrade them selves and also upgrade app players all the time, so that new feature work, using say the * star button,(settings for many things)
min upgrades as I sleep, ROKU is the best there is, so good it is installed inside newer TVs now, yah it works that good.
NOT TV made works that good unless it has ROKU in it, OK???
see why, (answer the new apps update all the time, endless)

what does not respond mean
does the RUKU player work , on the main right side screen of ROKU, and MUST work on their web player channel this would be first test, not Netflix using logic of walk first then run.

Then see of you internet connections work. If the ROKU channel is dead, internet is next , mine has wifi and ethernet channels.
I use the latter, and NEVER FAILS, and we all know wifi is PITA.
(of 1000 reasons)
But you have wifi , I bet and that is a pain, if to far or too slow or the wifi channels are all overloaded by others in home or close neighbors (so move to higher wifi channels)>?

Tell again what "NO RESPONSE MEANS"
elaborate on just that,
1: the menus are missing , black screened?
2: what does not respond, exactly, what.?

on mine I use PLEX and I click PLEX and my PLEX server comes up. wow PLEX.
there are like 100s of APP players there are all dead/?

Contact ROKU they should be able to sort it out for you.

Unplug it. If yours has a reset button press it .

I presume you have a box and not a stream stick.Try unplugging ROKU box.Many units have a button you have to push on remote after plugging in ROKU box,this connect Remote to ROKU box.If this doesn't work take out batteries in remote and put back in,this has to be done after you plug in ROKU box.Are batteries weak,try some new ones?

Ensure the batteries are good., other than that there are no replaceable parts. If you have another remote from a Roku (borrow or beg a friend) try that to make sure the remote is bad and not the Roku 2 XD.

You may have to check batteries in the remote, and then sync your remote - see your roku instructions.

I WAS TOLD TO GO TO ROKU.COM/LINK TO ENTER THE CODE THAT I RECIEVED FROM ROKU ON THE TV, BUT I KEEP THE RESPOND INVALID. SO NOW WHAT AM I TO DO, SHOULD I RETURN THE ITEM BACK TO NETFLIX, I REALLY DO NOT HAVE TIME FOR THIS, CONSIDER YOU SHOULD BE ABLE TO PUT THE ITEM TOGETHER IN 3 MINUTES?
