B450 Aorus Pro RGB Issue

[AndyGamming]

Hi!

Last night I looked in the case and noticed less light than it should have.
The RGBs on the motherboard did not work, except for the ports that come out behind the case.
I closed the PSU from the button, left it for a few minutes, turned it back on and the LEDs come back on.
I enter RGB Fusion to change the colors, but there is a big surprise..the colors don't change ..
I tried bios upgrades / downgrades, bios reset by removing the battery, windows reset, deactivation of the bios settings, but in vain.
The LEDs are on even when the PC is turned off.
I tried to make changes directly from the bios, but no results.
What do you think it could be?
Can be this solved on warranty or should I wait for a new update?
