Did you uncomment the line Force_hdmi=1 in config.txt?? That forces the hdmi on even if it doesn't properly detect an HDMI monitor

Mark... Thanks for the speedy reply.? I followed your advice and burned a new SD card. This time there was lots of green blinking which finally stopped leaving only the red LED on. Still no HDMI.? I'm hoping you have an idea for further troubleshooting.? I've connected the Rpi3B+ to another HDMI cable and monitor that is currently working on my main PC.? No problem with cable or monitor.? 73 Doug K7KY

Your SD card is bad. You'll have to make a new one.? Use a class 10 card for years of service.?
