Is it possible that anything was spilled on the effect multiselector knobs? I have heard Line 6 effects potentiometers are very touchy to even slight moisture.
It was the first thing to come to mind with a year old in the equation.
Hope you get it workin!

nope. nothing was spilled on the amp at all. the only thing i can think of is since i live in florida, it could be damaged from the high humidity...... but i doubt it. its always inside with central air on. but IDK
I'm thinking you have 1 of 2 problems.... 1st is you have an issue on your audio board. Depending on what happened could be a number of things. Anything could be blown or shorted. First thing is to pull it out and check to see if anything looks like it is burnt or oddly colored. If you don't see any discoloration, I would think that you may have a blown or shorted IC/FET. You can't always tell if they are or not, so unless you know electronics then you will probably be in the dark. My suggestion is to take an extra speaker if you have it, making sure the volume is down and tap it into where your line out is on the board. If you have sound coming out, I was also thinking you may have a blown speaker. I know that when kids are plugging things in and out and messing with stuff they could have sent enough back fed voltage into the amp and blown the speaker. But these are just a few things you can check. Just keep us posted on what you find. I know pharaoh is pretty good with electronics, but plays guitar. I can ask my step dad, he's fluent in amps when I get a chance. I just know electronics in general. Best of luck!
I've made some progress!!!!!! I plugged in an instrument cable into the guitar jack and since i don't have any 1/4'' size headphones to plug in, i used a mic plugged into the headphone/line out jack. i was able to get a buzz whenever i pressed my finger on the end of the instrument cable. i think its possible i DO have a blown speaker...... or am i jumping to conclusions?
OK. I just plugged in my guitar, and plugged in the mic as a speaker for the headphone jack. I was able to get my guitar sound from the mic, so i'm starting to feel like either the speaker is blown, or what i feel is more likely since i hear no humming or buzzing or anything at all, it that there is some fault in the wiring between the power amp and the speaker itself. i have the soldering in the above pic. on the surface it seems fine, but i'm wondering if there is some infidelity somewhere
i haven't had access to another speaker to replace on the amp. i also read that i need to match the ohms and watts for the speaker
You should be able to just use any old speaker to test it out. It won't hurt if it is a bit different. Wattage doesn't matter as long as you don't turn it up.
