I have a #Roku Express 4+ device that has stopped working. The "on" blue light in the device is on. The remote control will turn on and off the Samsung, along with adjusting the volume. I will select the HDMI source it is connected to and doesn't register on the tv. I have tried unplugging it and plugging it in, tried it on different TVs, and pushed the reset button. The device is about a year old.
It is a Roku Express 4+,model 3941X
Any assistance would be appreciated.
