Last evening everything worked fine. Today I tried to watch TV via Roku and the TV said there was nothing connected and the light on the Roku was out. I pulled the power cord for a few seconds and then plugged it back in and it started to boot up, with the animated "ROKU" on the TV and the power light on. After about ten seconds, the power light started blinking, then went dead again. The boot up screen disappeared from the TV and the Roku is dead. Every time I try it, the same thing happens.
