How to check the lamp replacement counter

You can check the accumulated illumination time of
the lamp as follows:

more than 20 seconds to enter the service mode.
2. The lamp replacement counter service menu is

the accumulated illumination time of the lamp is
123 hours. To clear the menu, press the POWER
