Question about Panasonic PT-LB20U Multimedia Projector
Sometimes the lamp turns on for a few seconds without fan, green button turns red. Original lamp lasted less than 1800 hours. Was always used in low power mode. After lamp replacement projector functioned for a short time, lamp time never reset. Was serviced under warrantee after lamp replacement. I suspect time accumulation on counter prevents start. No menu item to reset lamp time.
Press the MENU button to display the "MAIN MENU", and then select "OPTION".
Press the ENTER button to display the "OPTION" menu, and then select "LAMP RUNTIME".
Press and hold the ENTER button for approximately 3 seconds.
The "LAMP RUNTIME" will change to "TIME RESET [POWER OFF]".
Turn off the power and disconnect the power cord.
This will reset the cumulative usage time for the lamp unit to "0".
