   Check for the symptoms on the models concerned, and take the following countermeasures.

   Power is not turned on even if a rechargeable battery or an AC adapter is connected.
   And "OPEN" indication appears only when the lid of unit is opened.

   Step 1: Measure resistance of R348 on the rear -panel side of main C.B. (See Fig -1) and
           check that the value is 2.2M .
           If the value of R348 is 100 , change the value into 2.2M .
           Note that a 100  resistor is connected in parallel with a 2.2M  R348 resistor.
   Step 2: Remove Q303 on Mechanism side of MAIN C.B. (See Fig - 2), and re -mount Q303
           in reversed direction (rotated in 180 degrees).
          Check "VK" indication on Q303.
