Phenom fans stopping when LEDs come on

I have been printing for over a year on a regular Phenom and now the power seems to be dipping below the level needed to drive the fans every time the LED array comes on. I have tried replacing the external power brick (didn’t help), so I think there must be a problem with one of the internal power boards or the LED driver. It runs just fine until the lights come on, but I don’t want to melt the printer by running it this way.

Please check the internal circuit of the device,

If the above checks still cannot solve the problem, please contact by email, so that the peopoly technical team can help you in time, thank you for your support
