Does a Roku Stick Work on Any TV? The Roku Streaming Stick 4K is designed to be compatible with any TV that has an HDMI port. This means it will work on both smart and non-smart TVs, as long as they have an HDMI connection.
If your TV is analog, don't worry! You can still use the Roku Streaming Stick 4K by using an AV Composite Converter. This will allow you to enjoy all the features of the Roku Streaming Stick on your TV.

All Roku streaming players will work for any television with an HDMI connection, so any Roku player can be connected to a 4K UHD or HDR-compatible television. However, to stream movies and TV shows in 4K UHD or HDR you will need a compatible Roku streaming player and television that supports 4K UHD or HDR.

lost the free manual? it has simple instructions.

no RoKU stated model, saying just Roku means nothing, oK>
it has a real name and model, just like you unstated TV.
lots of Roku)
I have the Ultra (non Dongle) not the STICK.
mine is (best) a floating box. with 1 AC power pack (see?)
and is not optional.
first is power, the Ruku must have power.
then on mine power light on the roku glows
next is internet
and last is hdmi connected to TV.

Power, then internet and hdmi.
finally is TV set to TV's hdmi port number that is ROKU.!
if our ROKU is only a streaming stick (DONGLE)
it steals power from the TV HDMI port.


mine is ethernet connected for max performance

my guess is you have the TVs input selector set wrong
wide guess blind to true MODEL I am, non stated
good luck
and nothing beats a ROKU,
for 1 reason the player apps in it all work and are updated for free.
That is why TVs no come with ROKU inside for that 1 reason.
I use ROKU plex and to my own private servers.

Get a short HDMI cable extension, with a male connector on one end and a female connector on the other. Best Buy may offer them. There is also a very short HDMI adapter that allows up to 90 degree turn so the Roku will lie outward., also available at Best Buy or TV specialty stores. Finally, try using the HDMI side port on the TV's right side (to your left as you face it).

Sounds like you have a bad connection on either your roku stick or your HDMI PORT.Does you ROKU stick show a white light if not check power cable or electrical plug.
Try wiggling ROKU stick just a hair or push it in and out until you get a signal..A purple screen with the words ROKU should show up on TV.If you have a bad port on TV it would have to be replaced but this is rare,if you have a second port on tv try that.Have you tried your ROKU stick on another tv?Does your streaming stick go in vertically or horizontally,if it goes in vertically it may be pressing against side of tv prohibiting a good connection.You could try a HDMI cable, plug the HDMI cable into tv and put ROKU in other side of cable.There is also a restart button on ROKU stick push it and it will start blinking,if it doesn't light up you may have a defective ROKU stick.

Check for signal input at the HDMI port or Coaxial connection. Check your cables or try a different one. Be sure your signal source is handshaking with the TV set.

Go into settings on your tv & activate the wireless mode

Check the video output cable (HDMI or composite/RCA, etc.) from the Roku to the TV, to make sure it's still connected. Verify that you're watching the input on the TV that the Roku is connected to. If that doesn't work, contact Roku support. I hope your unit didn't just die.

you may need to change the HDMI board in the tv. it will be the hole board the parts are just to small to replace them all to get the HDMI board working again. find a second hand replacement. should be fine with another known working one.
