Remove the electrical appliances and check whether the internal connectors and wires have fallen off or loosened, and whether the printed circuit board has broken or damaged. Resistors, capacitors, transistors, integrated blocks and other components have no burning, bursting, defect or broken feet, detachment. All sensors, detection lights and adjusting switches are damaged and shifted. Whether the transmission belt and gears are deformed, aged and falling off or not. Whether there are displacements, deformations and damages in the belt-taking mechanism and transmission connecting rod, and whether the moving parts are flexible and free. Is there any fire and smoke in the back of the power-on test machine?  Whether the magnetic head is broken or not clean.

2. nose sniffing

Smell with your nose if there is any burning or other odor in the appliance.

4. manual

Gently pull the connection, plug, socket and components with your hand to see if they fall off. Pull the parts concerned and try their tightness, firmness and flexibility. After electrification, touch the power transformer, regulator, integrated block or other related components to see if there is overheating.
