Troubleshooting
This section provides common problems and their potential solutions. Solutions often refer to specific sections for component replacement.
Common Problems and Solutions:
- Jaw handle loose: See "Adjusting the Jaw Handle".
- Jaw handle cracked/rubs front panel: See "Replacing Components" section 2.0.
- Power button not lighting up: See "Replacing Components" section 3.0 (LED).
- Power button sticks: See "Replacing Components" section 3.0 (button).
- LCD/Touch screen not active: Verify front board power, cable connections, and replace front board or LCD if necessary (see "Replacing Components" section 4.0).
- Console powers down (E_ error): Check LED module fan (see "Replacing Components" section 5.0).
- Console will not power on: Check AC inlet filter fuses (replace with 5.0A, 250V fuses) or AC inlet filter (see "Replacing Components" section 6.0).
- Console emits light after cable removal / does not resume from Standby: Replace ESST sensor (see "Replacing Components" section 7.0).
- Light output flickers/intermittent: Replace ESST contact (see "Replacing Components" section 7.0).
- Light output no longer white: LED power contacts may be damaged; return for repair.
Error Code Definitions
- E-1: LEDs exceeded operating temperature. Return for repair.
- E-2: LEDs off despite conditions met. Return for repair.
- E-3: LEDs off due to electronics fan issue. Return for repair.
- E-4: LEDs off due to heat pipe fan issue. Refer to "Repair/Replacement" section 5.0.
