Hello Flavio,
I had to bring my Q-24 to an authorized dealer here in Mexico. They told me they have to change the entire mother board and wanted to charge 1000 dollars for it.
I found another option for half the price, an engineer who told me that the mother board CAN be fixed. So for now we are waiting the original parts to be replaced from China.
I hope it will work.
Al least he managed to turn it on again without all the leds lit.
But it doesn´t complete the booting.
I attached the video the tech sent me
