Hi All. I've got a Topping D50 with a burnt out DC/DC converter. I think I can replace the converter chip TPS65130, but more concerned with putting in new resistors, which is going to be very fiddly, and what damage has been done to the circuit board. Rather than the replacement and repair route is there a way of bypassing the whole DC/DC convertor with a separate unit?
I'm a novice but happy to try a bit of soldering/ desoldering for the learning experience.
The unit still powers on ok, but no sound output. What do you think? Seem to be a lot of valuable components here, is there any way to salvage something, or is this just a coffee mat?

As from TPS65130 datasheet you can locate output capacitors, check if there's no short circuit, desolder TPS, check for shor circuit again and apply proper voltage to output caps.
