If the problem persists after all attempts of component replacement, then the motherboard may require repair or replacement. The motherboard can be repaired or replaced if it is within the warranty period of your reseller and/or with MUJO Advanced Research. Check with your reseller for their warranty and exchange policies. Please note that MUJO Advanced Research cannot honor a warranty period set by a reseller that EXCEEDS MUJO’s warranty period. If your reseller is out of business or no longer supports your MUJO product, MUJO Advanced Research will accept a direct RMA with the Original Purchase Invoice.
