Monitor Problem

I usually have my latop plugged into my HD TV in my bedroom and use the Tv as a monitor but the other night the power went out for a second and when it came back on my TV was no longer getting a signal from the laptop. I’ve dug through the menus on the TV and the Display settings on the Laptop but I can’t figure out what the problem is, I was wondering if any of you might have an idea or could point me in the right direction.

The first thing I would do is try to isolate the problem. Have you tried outputting your laptop to another monitor? How about outputting from a different source to the TV?

Sorry it took me a little bit to get back to you. Holidays n all. Anyway yea i plugged it into the TV in the living room through the HDMI port and it worked fine so I guess it must be the TV, tho I forgot to check if i had sound or not. I plugged my PS3 into the Tv in my room to see if it still worked and i got picture for the PS3 but no sound which was odd.
