1. Make sure that the light cable is inserted, the bulb
door is closed with a bulb inside, and the lamp is
not lit.
2. Check the voltages on TP22 and TP23.
• If the voltage diference between TP22 and
TP23 is not 12V, replace the control board.
• If the voltage diference between these two test
points is 12V, ensure the J3 cable is connected
properly to the ballast and that the individual
wires are not crossed.
- Ensure that L3 and L4 ferrites, located
underneath the J3 connector, are
soldered properly to the control board.
- If these ferrites are missing, broken, or
not soldered properly, repair or replace
the control board.
3. If none of the above steps resolves the problem,
replace the ballast. |
