Hi @Tommyc21,
A warm welcome here in the Roku Community!
We understand you're having a problem with the Roku Express 4K. We're happy to help you. Please be advised that running with insufficient power can lead to instability, crashing, and other unpredictable behavior. If you have suspected that the TV itself has the problem, if possible, we suggest you try to plug the device into another TV and if there's any difference after.
You can also check out this support article here on what to do if you cannot see the picture from your Roku streaming player on your TV.
If the problem still persists, please keep us posted.
All the best,
John
The post you replied to did not get carried along with your post on this $#@& forum software so we don't know what "exact same problem" you're referring to. Can you supply some more details?
