Receiver Shuts Off Only When TV Input Is Used
I think your Receiver is going into protection mode. This happens especiaally when speaker cables are not connected properly. They are either loose or are touching each other or to the body of the receiver or the speaker ha blown.
You are lucky that it has not blown any transistor of your Receiver.
Please immidiately disconnect all your speakers cables and the cable form the mian.
Reconnect only the cable from the main and try to select the TV, it will switch on. If it switch on then you can be sure it were the speaker cables.
Now power off, main cable off, put all the speaker cables back and see if the everything all right.
If you still have a problem, let me know we can futher trouble shoot.
Best of Luck.
