My line 6 spider III 15 watt amp isnt working properly. i turn it on but i get this sound when its connected to the guitar. it sounds like when a guitar is not connected to a guitar and the guitar cable is just left on the floor. thats how it sounds like. it sounds really buzzy and it wont take off even if its connected to the guitar

While it could be true that you're having a problem with the guitar or cable as the previouse expert suggested, to say that it can't be anything else is false. It could be a jack problem...it would only be apparant when the jack is making contact with a cable. I do think you should test it with another guitar and another cable but if that is not solving the problem then I bet it's a problem with the input jack of the amo itself or even one of the ionternal components (this is a digital amp and there are MANY components and settings that can trigger a problem like this) If the problem is not solved with a new cable/guitar configuration then it's time to take it to the shop.
You need to do some swapping out of cable, amp and guitar with other cables, amps and guitars. Zero in on it by the process of elimination. I've played for 50 years, and in fact own a new Line6 Spider IV 30. If I had to guess, just based upon experience, the most likely problem is the cable - likely on one end or the other. Start with a new cable. Don't penny-pinch. You get exactly what you pay for with cables. If the problem persists still, have a friend bring over his/her rig (guitar cable and amp). Surely then you can figure it out - and you'll have a new cable to boot. Good luck. I doubt VERY seriously it's the amp or the axe.
This sounds like either a bad guitar cable or a broken ground in the guitar.
If amp is quiet with nothing plugged in, the amp is OK.
