[QUOTE="Danny Avila, post: 211436, member: 2957"] Hi Marcel Jansen. I've serviced this XTi platform for years and all sort of Firmware odds and bugs during boot up process came in a vast majority from corroded cooper traces or drills around the CPU or DSP ICs. Moisture/dew coming in from front grille (condensation in some cases), can destroy drills in the circuit, disconnecting upper from bottom traces and causing the CPU to detect non existing conditions like overheating, no temperature at all, low line level condition or no sound, even when the display says the amp is ready for use. DM me with your e-address and I will send you the file you want for flashing the CPU, but if the USB isn't working, chances are you wouldn't be able to connect with the CPU and download the corresponding Firmware file. I suggest you to inspect throughly the circuit board using the Service Manual schematics as a guide for point to point connections test between CPU, DSP and ADC and perhaps you'll find the flaw. D.
