Have a Roku 3 that has been installed & working for several years. Have read thru the other posts on the forum, tried the recommendations, still No Signal.
Yesterday we got a No Signal error, so did unplugged the Roku & plugged it back in (several times) and it finally reconnected. We had used the Roku earlier in the day without any problems. We used the Roku & TV several times after that & it worked OK. Today turned on the TV and a grid screen was displayed. Waited a few minutes, no change. Unplugged power & HDMI cable to Roku waited a bit & plugged all back in, got the No Signal message on the TV. Tried this several times, still getting No Signal. We have another TV/Roku setup so swapped this Roku to the other TV, same result No Signal message. Tried a factory reset on the Roku, plugged all back, in same result No Signal. Have also changed to a different HDMI port on the TV, again same result, No Signal.
What else can we try?
