ID this component/ smokey

[vib_ribbon]

Hi.

I've been enjoying my old arpicade a lot recently. Tonight, while I was playing a particular game, I noticed the sound was missing. When I powered my supergun down to restart it to see if it made any difference, this component on the board literally went up in smoke.

Can you tell me what it is so I could get it replaced? Hopefully that will fix it? Thanks.

Thats an AN7511 audio amp chip.

Replacing it should see you fixed up but it's also worth having a look at your 12v in case it helped the chip fail.

Also, please join us over at arpicade.net - it's the latest version of this forum.

Hi.

Arpicade.net is not sending me my activation email, can you check for me under the same username?

Also, I changed the AN7511 but still no sound. It's definitely getting 12v. Tried it on both my cab and supergun. Is there anything else I could do to narrow down the problem? Thanks.

Edit:
I decided to upgrade my pi3 to a pi5.
I also plugged some speakers directly to the DAC and I get sound from there, so the fault must be further down the circuit.
I put my finger onto the an7511 and it's very hot to the touch, the same with the pi5's CPU. I think I'll need to get the fan for the pi5.

I fixed it!!

The 3.5mn headphone socket was soldered rather poorly at an angle, so I guess when I removed the pi to do the an7511 repairs, I must have pushed/ pulled on it too hard so the ground pin was no longer making connection. I patched it with an ugly wire and now we have found again.
