          make sure you don't have a stuck key or non-function key===
          (Online Key/Cancel Job Key/Settings Key or Reset Key that is preventing u from getting into service mode ??
          keys should have a slight release upward when depressed>released

          Firmware Procedure
          1) Start up the PC.
          2) Connect the machine and the PCB with a USB cable.
          3) Turn on the main power as follows to start download mode.
          Shifting to Download Mode
          3-1) While holding down on the Online Key (a) and the Cancel Job Key (b), turn on the power.
          3-2) Press the Settings Key (c) several times; when 'SERVICE MODE' is indicated, press the Reset Key (d) to start service mode.
          3-3) Press the Settings key (c) several times; when 'F/W UPDATE GR.' is indicated, press the Reset key (d).
          3-4) Press the Settings key (c) several times; when 'USB' is indicated, press the Reset key (d).
          3-5) When 'OK?' is indicated, press the Enter key (e) to start download mode.

          no HDD>& receive e602///

          Note:Video controller PCB>>make sure to check & remove these connections also>especially J5
          on board-connector for optional HDD

          could be issues involving below(something bad)
          when did error start ?? (power failure/jam ??)

          remove Boot Rom>clean>re-seat ?
          remove memory>clean>re-seat ?
          remove DC CONTROLLER connectors>re-seat ?
          Bad Video controller PCB ?

              Re: Canon LBP 5960 can not enter service mode

              I opened the display pcb and checked the switches but they seem ok ..also cleaned them.

              I cleaned the Boot room and the memory also....

              I checked J5 but no connector was in ...

              i also removed the connector of the Dc board and put them back in i did all this but nothing happened...the same problem...

              i try to enter service mode but no success and than error code e602-0002 back in ....

              Is there any other way to make firmware???

              Also Teckat in you opinion maybe the dc board or the video board defective?
