Safety measures must be taken by the repair technician during servicing: -When the supply is on, avoid touching the SMPS Board and the high voltage filter capacitors (2203

13、or 2210). -When the supply is off, make sure to discharge the high voltage filter capacitors (2203 or 2210) with a suitable value resistor before any servicing to prevent electric shock. 2) The flex cables are very fragile, care should be taken not to damage them during repair. After repair, be very

14、 sure that the flex cables are inserted properly into the flex sockets before encasing, otherwise faults may occurs. Use a insulation sheet to prevent any damaged or short-circuit of the boards.
