My playstation2 was connecting to my new roku TV I got just this past year. Now all of a sudden it says "No signal (is it on?)" And I cannot get it to connect. It worked just last week. The ps2 is turning off and on just fine. Everything is plugged in and connected where it should be between the ps2 and the TV. I tried switching from HDMI1 to HDMI2 and that did not work. Is it a converter issue? A setting issue? I'm just not sure what to do next.
Have you tried a different HDMI cable or tried connecting the PS2 to another TV. It is possible the HDMI cable is bad or the HDMI port on the PS2 has gone bad.
From the Home Screen, select the HDMI Input, then press the asterick (*) button on your Roku remote and select "Remove Input". (I would remove them all). Then unplug your HDMI devices and perform a System Restart on the RokuTV. (Settings/System/Power/System Restart).
Then go to Settings/TV Inputs and Enable one of the HDMI ports. Plug only one of the HDMI devices into this selected port and perform another System Restart.
If the port is still not recognizing the PS2, try pliugging another HDMI device into this same port (maybe a DVD player or laptop, etc) and see if that is recognized. Need to narrow down whether a RokuTV issue or a device/cable issue.
