You have an analog only monitor on the RPi.
dd bs=1M if=/home/geoff/Downloads/RAT_RC1/RAT_RC1.img of=/dev/sdb1 3000+0 records in 3000+0 records out 3145728000 bytes (3.1 GB) copied, 239.58 s, 13.1 MB/s
Should be /dev/sdb if that's the location of the SDcard. /dev/sdb1 is the 1st partition on there, and that image needs to be on the boot block.
RPi3 red LED lights up, and that's where it ends. No monitor action, no nothing else.
You should at least see the "bios" output if the SDcard is bad, IIRC. I'd try the sdcard and find a HDMI/DVI monitor, or just plug it into your tv :) 73's -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net
