Bass problems

So after 8 months, i finally have a problem with my bass. I plugged everything in, same as usual after band practice last night. And theres no sound. I know its not the amp or cable because if i turn my amp on and plug in the cable from the amp, I can hear the noise when I tap the end of the cable.

So I opened up the back of the bass and all the wires seem in order, none are disconnected. Could they still be not working if they are still soldered together?

Any ideas on what possible problems there could be?

Its an Ibanez GSR 190, just put new rotosound strings on it a few days ago...

Ill post pictures if you need it

Thanks in advance

is the bass active??
cause the battery might need replacing
although i doubt it

Theyre passive I think

Turn up the volume knob on your bass.

I seriously forgot to try that.

Ahhhh wtf, works now. Dunno whats changed. Before my tuner wouldnt recognise any sound and the bass wouldnt make any sound. Now its fine...

Ah well, cant complain

probably a dodgy wire sumwhere

Nothing that a good soldering wont solve if theres any other problems
