The diagnosis of electronic appliances is not a straightforward task and oftentimes electronic components can appear to be faulty, when they may not be. At the time of Purchase We STRONGLY encouraged you to engage the services of a qualified service agent to diagnose and test your machine prior to purchasing a circuit board. By purchasing this item, you agreed that the item you are purchasing may not fix the fault in your machine. Sometimes the fault in circuit boards can be a result of a fault in another component, and fitting a new board to the machine can result in damage to the new board as well. Electronic components can in some cases be damaged by static electricity, water, or some other factor. Because of these factors, this PCB may not be returned for credit under any circumstances, whether it has been fitted to your machine or not.
