Cable boxes have notoriously flaky HDMI outputs. I have seen No pic and no sound with their HDMI outputs as well as a host of other problems. You can try getting the cable box replaced; unfortunately I have seen multiple cable box replacements not fix the problem. The best solution is to leave the component cables connected; you're not losing hardly any resolution/picture quality by using the component instead of the HDMI. Solution #2: switch to a satellite provider. I rarely see HDMI problems with satellite boxes

Most laptops have a combination of buttons you have to press on the keyboard to get it to output on the monitor output. Try pressing the FUNCTION KEY or FUNC/FN key usually found in the bottom left hand side of the keyboard. Keep that button held down while press one of the number keys. Usually the number key will have a picture of a TV screen on it. Might be number 8 or 9. Press both keys at the same time a you can switch between laptop screen, Sony LCD or you can have both..
