My console has three flashing red lights or an E74 error. Is this covered by warranty?
The warranty period for three flashing red lights and the E74 error is three years from the original purchase date of the console. If your console is out of the three-year warranty period, you can still receive console repair service for a fee.
When trying to raise a service ticket, it states that the box is out of warranty and is charging me the full service charge. I've tried contacting their customer services dept via the online and they're claiming that's only the year, despite their website stating otherwise..
Wasn't sure what to do next or if anyone had any advice?
