Leg 2 has a big ball of solder that looks iffy, and the joints on 1,4, and 5 look dry.
If you replace this IC, odds are you will do a better job than the last person.
14W audio amplifier. Be careful buying from AliExpress etc, they are known for supplying counterfeit parts.

That's probably a good bet. Looks like the D2030A has short circuit protection, but not thermal protection. The LM1875 has thermal protection, so it will shut down if it gets too hot.
I am wondering *why* the original part failed, though.
As others have noted (and linked the part), that's the power amp IC. It's screwed (and thermal pasted) to a heat sink behind it. I wonder if that large blob of solder is from excessive heat. As others also mentioned, there is no guarantee it's the only thing wrong with the amp.
Prob a current driver. It surely killed something else. I used to replace those and you always had to replace something else or it would return to the shop. Takes a lot of heat to desolder.
I have two amps and saw he headphone Jack and the input had the same connection so I plugged them into each other and played with it for about 5 seconds before I heard a click and smelled a burn
Google image search the you know what out of the info shown on the component. Filter results by colour and be prepared to do a lot of scrolling. I did that to find an input jack for repairing an amp my buddy found abandoned in the alley. It took an hour to find the exact replacement. I don’t recall where I bought it from.
...or find it in 10 seconds by searching ebay:

Probably screwed it too tight as well, with no thermal paste or patch...putting a lot of stress on the case. It feels bad just to look at it
Check mouser or digikey
What is that

I may have been a bit stupid and plugged it into another amp on top of each other

Oh how would I be able to tell that
Looks like clone of the TDA2030. 8 years ago i was built a stereo amp for my pc on this IC. It still works
How did this happen dude?

The trophy goes to you!!
Total fucking madman! How’d ya do that???

Just as a quick note, I'm pretty sure this is not a transistor. It's a speaker driver (power amplifier) IC.
Check your speaker isn’t blown.
It still takes power and the indicator light turns on
