Same problem here. Tried to just reload the Firmware several times via USB… kept getting an error 010 at the end. Was a bit skeptical of above so I initially just unplugged everything from the mother board with the exception of not removing it and therefore not disconnecting it from the board on the side, and then re-assembled. Booted up and again tried to reload firmware several times via USB. Same error at end. So then I removed the board and baked at 390 for 15 minutes per the above, AFTER removing the one piece highlighted. Let it cool, reattached everything. Then tried to update the Firmware via network. It finished quickly, but still no sound. Lastly, I tried again with the USB method and SUCCESS!! Everything is working fine! very very strange… not sure which step fixed it. a) removing the board from side board (complete disconnection), b) baking, c) trying the network method first, but ITS WORKING!!! Cheers.

That’s great news! And thanks for the detailed response. This is a method I have used for several computer systems that developed problems with their GPUs. I believe what is happening is that over time with the heating and cooling cycles the solder joints under the chips themselves develop faults and eventually stop conducting properly. Basically this baking process remelts the solder in the connections and allows proper contact to the GPU or CPU or whatever chip it is. So far this fix is working well for me so I hope you experience the same.

Doing this right now, so thank you very much! Question, on removing the capacitor before baking - any tricks to get it out? Or just have to unsolder it.

Dan Dunham - Jan 13, 2019

Hey Kaleb,. I missed you question but to get that cap out you’ll just want to desolder it with a desoldering tool of some sort and pull it out. You could just heat the lead up and pull each side out individually but that’s going to put more stress on the cap and is kinda messy.

Hi Dan,

it’s amazing if I heat the DTS component with a hair dryer and then I turn on the RX, the sound is there directly. And if I cool or that I turn it cold you have to wait between 5 and 10 minutes!
