There is no blinking light, its my screen. The roku itself blinks on and off. I cant even browse the roku menu because it blinks on and off so consistently that i can barely make out anything on screen and its not my tv because ive been watching cable waiting for a fix to this issue.
I got the new ROKU Express 3900 to replace an older ROKU 2. After it updated software and I logged in, the darned white light would not stop blinking! Even if the TV is off, when I walk past it, it almost seems there is an internal sensor. ROKU also started over again and again and again....while we were trying to watch a show or movie. So I unplugged the new unit and put the old one back on. Same issue! BRIGHT blinking white light, even when all of the lights are out, TV set to "TV" and turned completely off, but the obnoxious light started doing the same thing, now on my older unit that I had disconnected, then reconnected. But someone else recommended that I change the HDMI port AND use the "high speed" cable that came with it. I did that today and so far, so good. Hope it's resolved. - JT
Hello, I had the same problem. Excessive ROKU blinking and slow response to my remote commands. Then getting alerts from the different channel APPs that I wasn't connected to the internet for starters. The internet WAS up and running for all the other technology in the house! I forgot my work "IT guy" training (which was "is EVERYTHING plugged in properly?") and instead forgot that went through all the unplugging of MODEM, WIFI ROUTER, waiting, getting back on and still with IFFY results. Then I replaced batteries on the ROKU remote. No change. Still blinky blinky no worky. Now, I'm not saying this wasn't part of the problem...the MODEM, ROUTER, but once I unplugged all the ROKU connections from the back of the TV to the power source and made sure ALL connections were secure for the ROKU and then plugged ROKU back in to the HDMI slot, the blinking stopped and It worked perfectly.
Two guesses, my ROKU parts connections were loose, the ROKU was UPDATING info to my "smart TV" and I didn't have the patience to wait or a combo or part of the above. Hope this helps someone.
SIDE BAR: I do have the ROKU HDMI extender on my TV because a couple of years ago I was having buffering problems even though the TV is plugged into the MODEM directly. The extender solved the problem.
I'm having the same problem BUT it is my Roku Ultra that is doing it. I bought it last September and this LG TV in December. Both have have worked just peachy! Any ideas?
