rick1109, try this. I am using file 6/24. after installing this file, check to see if your maxhd is working. if not, go to menu, installation, antenae setup, have it on echo 7, change your port to a different port, save, then exit. go back, do the same procedure, but change echo 7 to the proper port, save, exit. let your unit reboot for about 20 minutes, then see if you have a picture. why this worked, i'll never know, but been up and running for about 2 hours. seen that waldo69 had tried this, worked for him.
