Black screen momentarily flashes the video. Video is only displayed for less than a second. Input continues to work even when the screen is black. Last week everything was OK. It started with only occasionally black screen. Continues to get worse, black screen stays longer and longer.. I've tried resetting and restarting, power down/up etc. I suspect a bad unit.
Any suggestions?
Could be a bad unit, but did you try a different HDMI cable or HDMI port on your TV?
Yes, I tried a couple different cables and both HDMI inputs to the TV. I also checked the computer to TV connections and all's well. I'm out of ideas to try. I'm sure sorry I didn't keep the receipt. Looks like this one is bound for the dump.
