Anyone tell me what's wrong with my TV or is it my PS3?

May be...

I just bought a PS3 in May of this year, and I just moved in back to my dorm in Septmber. The TV is new and everything, and lately everytime I turn my PS3 on, the video and audio work, but my TV acts like I put in the input/output cables in wrong. I'm using the cables that the PS3 came with, and my TV is just a standard TV, and what it does is it gives a weird noise, and there are lines that come up from the bottom of my TV. It isn't very bad, but bad enough to distract me from gameplay. Do I need like a new input/output cord or is it the TV?

Make sure you have the cords connected correctly and make sure your display settings on the PS3 are not trying to output with a format that your TV does not accept. If all else fails, try another set of cords.

Maybe it's the cable or a shortist on the line. If I were you, I would ask one of the cable guys and see what they say about that.

why dont you try using the hdmi cable instead. it sounds like a cable or two might actually be touching each other. depending on how much power or frecuency is being run through those cables, if they touch, that can happen

try it on a different TV, if it still does it you need a new cord, if not you need a new tv

try using a different cable i'd say

it might just be the i/o cord thats all...

try testing it out with other ps3 cords...

see wat happens...
