TV reboot problem

This morning we went for hair cuts had to wait for the operator to show up.  For lunch I made chicken salad sandwiches and left over cooked squash. For evening we had a green salad. This evening after the game shows I started to Re Boot the TV and after the TECHNICOLOR there was no count down on the box and I received NO SIGNAL. So I just turned the TV off and will work on it some other time.
