AMATEUR REPAIR METHODS CAN MAKE THE PROBLEM WORSE, HEATING UP THE CONSOLE IN AN OVEN OR USING A HEAT GUN CAN DAMAGE THE MAIN BOARD.
Infra Red re flow of Xbox GPU at our electronic workshop in Manchester.
The Error 74 problem is similar to the Ring of Death. It is caused by connections called BGA solder joints, breaking. This method of connecting the GPU and other chips to the main board can fail more easily than normal solder connections. X-Ray examination of faulty Xbox consoles have found gaps in the solder caused by poor manufacture processes. These can cause the electrical connection to fail.
The only reliable method of repairing this problem, is to re flow the solder on the BGA chip. This can ONLY be done reliably, using an INFRA RED BGA REWORK STATION.
The method we use to repair Error 74 faults is the method used by Microsoft to repair this kind of fault.
Methods involving putting the main board in an oven, will not repair the solder joints. All the plastic components on the board would melt before the correct temperature (required to re flow the solder) would be reached.
Error 74 is a more temperamental fault than the Ring Of Death. The solder that is failing can be on a different chip than the Ring of Death fault. If the fault returns within 3 months of the original repair, we will repair it again free of charge, but it is your responsibility to cover the courier costs. Courier collection and delivery is currently £15 anywhere in the UK.
If a previous repair has been attempted on your Xbox 360, don't use this service. We will charge £20 to work on consoles that have been 'repaired' by novices even if the unit does not recover. Novice repair methods of heating the board up cause the pcb to warp. It is then impossible to get a correct re flow of the solder because of the curvature on the PCB.
The Only way to properly repair this problem is to use an Infra Red BGA re flow of the solder.
