How to Reset the Lamp Hours on a Toshiba DLPby Shawn Farner
Many projectors, including Toshiba DLP projectors, contain a menu feature that reports how many hours your current projection lamp has been in use. Projection lamps have a limited lifespan, and knowing how many hours you have on your current lamp can help you decide when it's time to buy a replacement lamp. Of course, when you install a replacement lamp, you'll likely want to know how much life is left on that, as well. That's why it's important to reset the lamp hours on your Toshiba DLP projector after installing a new lamp.
Pull the projector's power cord from its outlet. You can use this opportunity to place the projector closer to the outlet if possible. Make sure the power switch on the back of the machine is set to the "ON" position.
Press down on the projector's "ON/STANDBY" button, as well as the "MENU" button and "KEYSTONE" button. Hold these three buttons down simultaneously.
Plug the projector back into the power outlet while continuing to hold down the three buttons. Wait until the projector beeps and the orange "Standby" light turns on. When you power the projector back on, the lamp hours setting will be reset to zero, giving you an accurate way to track the number of hours you've put on your new projection lamp.
