I was wondering if anyone else has had any issues with the Roku TV taking awhile for the picture to come on ??? My Roku TV is about 5-6 years old but twice before I had an issue with it taking 10-15 minutes for the picture to come on , had sound , and then yesterday , August 1st , the picture would not come on at all , most of the day , and the light at the bottom kept going on and off and getting real bright , like it was restarting , and when I tried the remote app on my phone it said the TV wasn't even on , after I had turned the TV on , so was wondering if it's time for a new TV or if maybe Roku was doing some kind of maintenance which is why the light thing kept going on and off all day ... Picture is fine now so ...
