I can understand sound not making it to the TV. The default is for the 2807 to pass video only, and to route the sound part of the signal to its own processors. There is a setting in the HDMI assignment menu that allows you to choose whether the audio goes to the 2807 (Amp) or the TV.
If you're not getting video going to the TV however, I can only think of 7 reasons why it would not be passed:
1- you haven't assigned the HDMI inputs to input sources. You definitely need to do that and you'll find the "HDMI In Assign" options in the Video setup menu. You need to tell the 2807 which sources (DVD player, etc) that you want the signals from HDMI 1 and HDMI 2 to go to. If the 2807 can play audio received via the HDMI inputs then you've obviously got this part right but if you're not getting sound from the 2807's speaker connections, then this would be the first place to start checking.
2- you've mixed up the connections on the back of the 2807 and you have the output to the monitor connected to one of the inputs. If that's the case, you will also have the input from one of your sources connected to the monitor output socket. Check your connections.
3- the HDMI input sockets are faulty or damaged. Since there are only 2 and you have both in use there's no easy way to check this.
4- the HDMI output socket to the monitor is faulty. Connect a source to the 2807 via an analog video input and turn on HDMI conversion for that input. Connect the TV to the 2807 via an HDMI cable and see if you get a video signal passing to the TV. If you don't, and you don't get HDMI signals from your sources passed to the TV, then the HDMI output socket may be faulty/damaged.
5- the HDMI cable from the 2807 to the TV is damaged. Replace it with a different cable and see if that makes a difference. If it does, then it's a damaged cable . If you only get video from one of your HDMI sources, try replacing the cable for the input that doesn't work since you may also have 1 faulty input cable. Worst case scenario is that all of your HDMI cables are faulty but you can verify that by trying a new cable to the TV and a single new cable for one of the sources, then swapping that new cable to the second source.
6- you do have the TV set to the HDMI input, don't you?
7- if none of those possibilities is the problem, then the one remaining possibility is a fault in the 2807's HDMI processing.
Really, those should be the options for why you're not getting a signal passed to the TV. You can fix the assignments, ensuring things are connected to the right input and output sockets, the cables if one or more is faulty, and the TV input selection yourself but faulty HDMI sockets or processing in the 2807 are going to mean that the 2807 needs servicing.
