Hello, I'm from Sydney recently stuck in an RMA situation.
Where valve itself can't do anything. My steam deck has this situation where it doesn't boot anymore even through USB. I'm located in Sydney and as a last resort want to get it all fixed up or fix it myself but not enough knowledge on root problem, I know the battery itself is faulty due to it not working just the last time.
So please provide any technical advice or repair stores near Sydney.
What did valve say? What's the reason they can't fix?
