Question about BenQ PB8220 Multimedia Projector

1 Answer

The projector shut off during operation

Our PB8220 DLP Projector was plugged to the wrong voltage and the lamp power supply damaged (euc 250 p/01). This is the one that drives the current to the Bulb. Would you quote me one? Thanks Daniel Rodriguez 6789386517

It is highly unlikely that you will receive any quotes here; this is a repair website, the only sales would be through links on Fixya pages. I'm sure you can get info on price and availability at the BenQ site:

Check the voltage at the lamp input from the ballast after connecting projector to mains supply. (Warning: Do not switch on the projector while checking the voltage. It will damage your multimeter) The lamp connection shall be removed. If the voltage is around 60 to 80 volts AC, then your ballast is OK. Check for fragments inside the lamp.

Hi, My hc1500 Is having a problem. When I turn it on it makes a clicking sound. Then the Lamp fails to light. The Light is green and the status is green, but soon after the projector shuts off the power...


The clicking sound is the high voltage power supply trying to
ignite the gas in the lamp. The lamp is not firing and coming on.
Check the bulb/ lamp life. Possible the lamp has exceeded its
useful life and may need to be replaced.

I just replaced my bulb on the toshiba tdp t45u projector and the red lamp light is still on and the projector still wont come on? how do i fix?


Check out the Power supply to the lamp . It must not be high . . Check if the voltages are correct to the lamp's unit and it's PCB [printed circuit board]. I recommend using a service manual .
.............................................................

Here is how to replace a projector's bulb correctly :

1:Make sure that your power switch is off and that the power cord is unplugged from the electrical socket.
It is also wise to unplug any other cables and label them in order to restore them in the right way once the lamp is replaced.


2:In order to see the lamp, remove the access handle on the outside cover. You may need to use a screwdriver.

3:Pull out the used lamp and clean the relevant parts using micro fiber products and not paper.
Please note that in some projectors a small inside filter should also be replaced.


4:Insert the new lamp into the projector carefully avoiding touching the glass of the lamp itself.
Touching the lamp will deposit skin oil that will likely damage any new lamp during use.





5:Reassemble the access panel, replug the cables and power up the projector.

Things You'll Need:
new projector lamp
screwdriver
micro fiber duster
Warning:
avoid touching the bare projector lamp
I hope this will help .

Projector keeps turning off every 5 mins


if just the lamp turns off and the rest of the projector is running, it's time to change the lamp. if the whole projector turns off (not goes through shut down), it may be a power supply problem.
