I attempted to change the color intensity & I somehow got a menu showing a process with 0 to 100% and channel #s & I lost everything. I now have 'no signal' flashing and '5od' on the HD box. I've powered off & on several times, nothing works
It sounds like you have changed the signal input on your tv to the tv tuner. Check for a button on your tv remote (not your HD box remote) that says tv input or tv video and press to cycle through the input options while your Hd box is on. If this is the problem, you should get a picture from the HD box after one of the button presses.
Were you able to get this working? It does sound like the TV input may have been changed, and as mrgordos has mentioned you should be able to change this back by using a button on your original TV remote most likely labelled as Source, Input, or TV/Video. Pressing this should toggle the input back again. Let me know if you need further help with this.
