With every XBOX SERIES S|X repair the console will get the following reconditioning done to it:
New HDMI port installed even if it’s just the IC.
New high quality Thermal compound on the APU.
Complete clean out of fan, heatsink, BR Drive and PSU.
Warranty seals kept intact where possible.
Occasionally after replacing the port, there may still be issues such as “No Signal” or reduced resolution. This could be because the HDMI control chip (IC) or ESD booster on the mainboard is also faulty.
We have the tools, knowledge and experience to diagnose and fix correctly.
