TC94B15WBG Replacement (DAC + Stereo Headphone Amplifier Chip)

Hi,

I have a switch here I am currently repairing and I’ve traced a short down to the TC94B15WBG component. I removed it and noticed a bridge between two solder balls so removed and reapplied the chip but short is still present so I am going to replace the chip but I am wondering if anyone has any experience replacing these and if they’re interchangeable as I have noticed the writing on the chip “EINL O” is different on different boards despite them being the same revision of board.

Here is an image of where the chip is located:

Also don’t have a stencil so has anyone tried reballing by hand?

Thanks.

Is the capacitor right under the Pi3 usb chip shorted to ground? If yes have you tried removing the chip to see if the short is still present?

Commentaar:

Nah that chips fine now. It originally had 3 pins blown off with the pads too so I had to initially repair the traces there, M9T36 power management chip has been replaced too and I think the final fault is this one here, which I think I actually caused myself.

This chip kept overheating like mad so I removed it and the short was gone then put it back without bridged solder balls but the short was still there so thinking the chip itself is dead.
