Sofa butler projection home Toshiba projector used only half a year, how the light bulbs will not shine? What is the cause of this? Today, the author shared with you the five common factors that led to the failure of the Toshiba projector bulb and how to avoid it. There are Toshiba projector friends do not miss, and later certainly use it.
Cause one: The power is not turned on or the projector's power switch is not turned on
Toshiba and other projectors have large anti-fault protection design, and they must be kept pressed for ten seconds before they can be turned on. Frequent switching and sudden power off will seriously affect the life of the projector lamp.
Reason 2: Aging on the circuit board
Due to prolonged high temperature and dust in the power supply area, the circuit board has been exposed to poor heat dissipation and static electricity for a long period of time. Some capacitors and vital components are prone to poor soldering and contact, resulting in unstable projector operation and occasional power failure. Bright phenomenon occurs.
Reason 3: The lamp is in the warm-up phase
When the projector lamp is in the warm-up phase, the brightness of the lamp is still very dark, and sometimes it is mistakenly thought that the projector lens is not bright. Just wait for 2-3 minutes and the lamp will gradually light up.
Cause four: The cooling fan has a problem
If the fan fails, the heat generated inside the Toshiba projector does not evaporate quickly. The light bulb of the projector does not work, and the internal components burn out, causing the lamp to burst.
Reason 5: The lamp life is up
Can replace or switch to spare light bulbs, to see if the spare light bulb is normal, if normal, it proves that the original projection light bulb has been scrapped.
How to Avoid Toshiba Projector Bulbs Not Lit
See here we all know what is the reason why the Toshiba projector bulb does not shine. But do you know that these are all circumventable? How do you do it? Please continue to look down.
1, projection does not last more than four hours
Toshiba projectors should not be used for more than four hours at a time. Otherwise, the interior temperature of the bulb will also be very high, which will easily cause the rapid decay of the lamp's brightness.
2, shutdown should have a short interval
When the Toshiba projector is switched between the on state and the off state, the projector should be kept for about 5 minutes in the middle of cooling time.
3, power to maintain consistency
The projector and the computer connected to it should be connected to the same power socket as much as possible so as to avoid sparking between the sockets when the power is plugged in and unplugged, which may damage the power supply circuit inside the projector.
4, switch, should pay attention to the order of operation
After turning on the Toshiba projector's power switch, press and hold the Lamp button on the projector panel until the projector's green light is stable.
