Update: i just came back from the store. I've been told that they're going to have the X3 serviced for the next 2 months. Turns out the problem was the motherboard and they're gonna try to contact Line 6 for spare parts. Should things go smoothly, the X3 will be in working condition, and the sale price will be 6000 Philippine Pesos from it's original 23,000. Now that's a good deal, provided that they can repair it. Keeping my fingers crossed.
