I am having a similar problem. I have a 48 inch NS-48D510NA15. If I accidentally turn off the tv and try to turn it back on, the solid red disappears, there is no blinking. I tried to unplug and hold down the power button for 60 seconds and nothing changed. I hold a flashlight to the screen and there is no activity on the screen. The tv eventually turns on after 10 or 15 minutes. Any thoughts? I purchased the tv in March of 2015, so almost 3 years ago.
