TI TPA3255 EVM - Need Help Troubleshooting

Hello,

I have the TI EVM3255 module that is not working and wondering if someone can help me troubleshoot the problem. I am a newbie in electronics and my knowledge is pretty much non-existent.

I bought the module but it was DOA. Texas Instruments sent me a replacement which is now working. I would like to fix the module rather than throwing it away. I need a subwoofer amp and this one will fit nicely.

When I turn on the amp, the FAULTz (D4) instantly lights up in red. No output at all when input and speakers are connected. Is it something that the faulty part/s can be identified? As someone who has zero knowledge, I do not know where to begin.

Any help is very much appreciated. Thanks!
