Don't know without part numerates and yes it can be replaced if the part is still available but I would asking what caused it too fail. No point in replacing only for it fail again.

It will be soldered from underneath, try removing the case work to access. Replacing it will be the easy part, finding why it died (as steve mentioned) will take some skill. Look for swollen capacitors, especially in the psu section.. Also check for any short circuits, eg; solder dags.
Also try not to get that white heat transfer past under the transistor on your skin, its bad m'kay. It will also need to be replaced and can be found at your local electronics store.

Did this happen from new, or has it worked for a while?
A repair tech may be able to fix this in an hour, it may take weeks by yourself without the right tools/skills. Don't take that the wrong way, but if you want to get back in action asap, that may be the best option.

yeah no doubt im no master but i do kindof know my way around i repair broken xboxes and stuff which i know is nothing like an amp mobo but i kinna know a little bit...i just got back from radio shack and bought some heat sink thermal compound and a T0-220 case npn silicon transistor..ill take a pic and uplaod it to make sure its correct.. nothing else looks unordinary to me and i cant find anything else that even looks the least bit fishy...im not too sure why it went bad, it just did lol...ive had it for about 9 months now and its worked perfectly until bout a week ago it would cut off and come back on when i turned down the radio head unit then when i cut it back up all would be fine...it was very random and very seldomly cut off... im hoping replacing this transistor will be all the problem is/was...and im guessing im gunna have to unscrew all 14 transistors to get the whole mobo out? xD gotta make this stuff so hard to get to haha

The burnt device is probably a STP60NF06FP N-channel MOSFET. The TIP31 is a general purpose BJT (bipolar junction transistor). It won't work, don't bother putting it in. It may cause even more damage if you do.

That MOSFET doesn't seem to be stocked for low-quantity orders at DigiKey, Mouser, or Newark. Post over in the Car Audio section and have the folks there recommend a suitable substitute.
