In my opinion, you potentially (pun intended) have a very serious problem. Your LOG shows the 15V supply rail out of tolerance at 19.46V. That is, nearly 30% high - it could be even higher at other times. This should never happen. Such excesses may permanently damage board components. Do not tempt fate - power off the equipment immediately before it self-destructs.
Replacement of the PS brick may be required and while they are available at reduced prices they are not inexpensive.
You have purchased a non-functional fake and I would instigate action to recoup my payment. I regularly purchase electronics out of China via eBay/PayPal and fakes are everywhere. My policy is to never return fakes ("it is against the law to post fake items" and in any case they are worthless - particularly if they are faulty) and demand a full refund. While this may require some effort in communication, PayPal has always come to the party. In my opinion, if you return fakes they are simply on-sold to other victims.
Yixunhk is well known as an eBay seller who will take you for a ride, both financially and technically. If you are considering a purchase from him, first do your research - Google the blog of fellow time-nut Mark Stephens VK2HMC, and his time-nuts posts. As another victim, he has a few words to say.
