First of all, hi to everyone 

Something happened to my amp and i need some help. I was playing my guitar yesterday on my Ibanez gta10 amp which comes with the ibanez grx70 jumpstart pack.
I bought a new guitar cable a few weeks ago and it was great. While I was playing, the sound just suddenly went off and all i can hear is a bit of a noise when i turn the gain up. The on/off light is still working, so i concluded that the fuse was not the problem. I think it's a solid state amp, since it has no tubes in it so can anyone guide me and tell me a few tips? i tried with another guitar cable and the amp remained dead. The cable is deffinately not the problem, but could  the problem be the speaker(it produces some noise if i turn the gain up). Can someone help me?
I tried plugging it in another place, but that still didn't fix it.  Thanks in advance
