Keep in mind the safety warningsThe safety instructions are shown as the labels or prin

45、tings on the exterior, the inside chassis or the parts, etc. Refer to the instructions when proceeding with inspection or repair.2. Use only the specified parts for replacementThe selected parts are used at critical area to reduce fire hazard or electrical shock. So when replacing these parts where

46、designaged with marks or marks on the schematic diagram or the parts list, ensure to use only the same parts. 3. Ensure to dress back the AC (Mains) cord to the original positionIf for some reason, the AC cord is moved or partially disassembled, ensure to re-route or assemble back to the original po

47、sition. The AC cord area is protected and secured by tubing and insulation materials for the sake of safety, so that no loose wire will touch and cause fire hazard and electrical shock.4. Check for safety aspects after inspection or repairEnsure all parts, such as screws or wires, removed during ins

48、pection or repair are secured back to the original positions, and check visually for any anomaly. Also check for any electrical leakage or resistance to maintain the safety. 2SA1016K2SA1376A2SC536K2SC2362K2SC3478A2SC37082SD8632SA13452SC33992SB631K2SA12092SD19532SD600K2SC29112SA16672SC43812SB8172SD10472SK366MPC1237HALB1641PC817BNJM78XXFANJM2114DOPA2604APHIN232CPTC74HC595APTC9163ANCXP8283278PCB Assembly910Schematic Diagram1112Schematic Diagram
