NO SOUND! NEED NEW MOTHERBOARD! FRIED REMOTE Control chip I think?

The board scorching concerns me a lot - it doesn’t look like basic surface level burn residue. You may want to find a schematic or 2 separate groudplanes and check for a direct short. If you don’t see one, you can repair it - if you find one, the board needs to be replaced. You may need to remove some shorted parts as well so make sure you check the PCB and surrounding components.

It looks like a pretty standard TI chip and I’ve been able to at least narrow it down to a few chips:

• TPA1517DWP (SMD?)
• TPA1517DWPR (SMD?)
• TPA1517DWPRG4 (SMD?)
• TPA1517NE (Most likely)
  • TPA1517NEE4 is an alternative part number found on the datasheet
    • Obsolete so hope the NE version can work in place of the NEE4.

I can’t find anything else beyond that based on the photo but that should give you a good starting point IF the board is repairable and NOT dead shorted. Beyond that you’ll need to sort out which one is in use here or if you can interchange it - hopefully you can, but you usually can’t but the pinout looks similar on all 4, so there’s a chance here. See if you can find a photo of a good board and rule it out beyond a question of which one it uses.
