2 years ago I bought 2pcs of PS-97 consoles with motherboard version 2.1, but one of them stopped working. The problem is that when it starts, it only shows a white screen and does not want to boot. I exchanged the internal 4GB SD cards and the battery, but still did not want to load. When connected to a USB cable, the computer does not detect it. I tried by pressing the Reset button or holding the Power on, but that didn't solve the problem. Is there a way to fix or reinstall the boot menu?
I'm uploading a video with the problem:https://youtu.be/Tz-gr-sIsDU
