My Original power supply is from LYD Lianyunda, Model LYD2405000.
Input: 100-240V ~2.5A 50/60Hz
Output: 24V DC 5A
Which is 120W
The one you linked to is a 12V DC 8A Output, for a total of 96W.
It does sound like you’re under-voltaging the unit. Someone else here tried to use a 10V supply, and had similar issues.
I didn’t find that model number on Amazon, but I did find it on Alibaba: 24v 5a Ac Dc Desktop Power Adapter 120w Switching Power Supply Li-on Lead Acid Battery Charger - Buy Ul Ce Fcc Kc Pse Saa Approved 24v 5a 120w Desktop Ac Power Supply Adapter Battery Charger,Class 2 Power Supply Input 100v-240v Ac To 24v 5a Dc Power Adapter,Led Strip Cctv Camera Lcd Monitor Massage Chair Air Purifier Coffee Grinder Product on Alibaba.com The video looks like my power brick.
