Removal of Microchip
Locate the Micro Controller chip near the center of the rear of the unit.
Note the small dot and groove on the right end of the chip. This is important for correct
orientation when replacing the chip with the new chip. Note that the new chip has the same
small dot and groove as the old chip. Carefully insert a small screwdriver under the side of the
chip and with a twisting action lift the chip out of the socket.
Installation of new chip.
Check new chip for any bent pins. There shouldn’t be any but it is always a good practice to
check. If any there are any bent pins, carefully straighten. Install the new chip exactly in the
same orientation as the original chip. Small dot and groove on the right end of the chip.
Test and Reassemble
Before replacing the rear panel, plug the unit into power supply and check for proper operation.
Reassemble front panel in the same manner as it was prior to removal.
