I’m in the middle of building my first RetroPie project. Here is my issue, I purchased a Tontec 9″ TFT LCD display from Amazon, when I power it on the LED on the controller board flashes red/green, in a YoutTube video I watched the LED is a solid green light. I am running a 12V 2A 24W eBay Power Supply AC to DC Adapter for 3528 Flexible LED Strip Light. What might cause this problem? Is it a defective power supply? Did I purchase the incorrect power supply?
Should I ditch the eBay power supply and purchase this one?
Nevermind, I found the problem, not sure if it was a defective power supply or one that wasn’t strong enough. Luckily I had a 12V 5A 60W power supply powering up my LED strips, I tested it and it powered my display just fine. Now I can continue. 🙂
