Will this service fix my problems?

A full diagnostic check should first be performed to eliminate all other possible causes for your symptoms, even if the symptoms match those specified on the common fault description.

If you send a unit in good working condition due to misdiagnosis, and our testing determines that there are no issues or faults with the unit, or if the part is beyond repair, then you will only be responsible for the shipping costs and a bench test fee of $39.99 may be applied.

IMPORTANT! If you are not sure that this part is the cause of the fault then we recommend that you do not go ahead with this purchase and instead seek further professional advice and diagnosis.
