Just purchased an HD/4K/HDR stick for my older LG TV (3 HDMI input ports). Setup went fine. Turning on the TV several hours later resulted in the "No Signal" issue. Unplugging/plugging back in worked until TV was turned off & on again. Tried every network/WiFi/cabling fix mentioned in this forum. No luck. Eventually, I would press the Reset button on the stick (whether the TV was powered up not) and everything worked. Somebody in this forum had mentioned the Auto Power Savings feature for the Roku stick. I assumed that this feature would turn off the TV after 20 minutes. Not so. It turns off the Roku stick's power. Go to:
Settings - System - Auto Power Savings and Uncheck "After 20 minutes of no interaction." This fixed the problem for me. If no luck, press the Reset button on the stick itself. This works, but you have to drag your ass off the sofa to do it. I hope this works for everyone. Good Luck! JPD
