I have a pj 305d projector that won't emit light. The green indicator flashes when pressed for about 1 minute, then goes back to orange. The red bulb light comes on after about one minute. There is no sign of heating or a broken wire on the bulb

Benq w1000 project not turning on


Look at the manual page 34, for the indicator messages. I suspect it's the same problem I have (which I haven't had formally diagnosed yet!), which I believe is a defective fan. My projector had been making a really loud noise on startup, which varied in length and volume. Recently the projector has taken to turning itself off after being on for about a minute, and the power light flashes green, with the temp and lamp lights flashing red.

After changing the bulb image will not come on and solid orange light appears


Other then POWER BUTTON light there are three lights more
1. lamp indicator
2. temperature indicator
3. computer input
witch one light is flashing RED or illuminated RED with POWER BUTTON orange light.
If LAMP INDICATOR light is illuminated RED than lamp runtime has reached 1800 hours. but projector still working.
If LAMP INDICATOR light flashing RED than lamp circuit failure, or abnormal function or lamp unit is damaged. In this case projector doing the same behave just like your projector.
if TEMPERATURE indicator illuminating RED the projector still projecting and if flashing RED than turned of itself

What does it mean when that blinking green light turns to orange one in lp 350?


Hi
This would be "Standby"
When you press standby, the display and audio turn off and a blank screen is displayed for 15 minutes.
You can change the amount of time the projector stays in standby mode; see “Standby Time” on page 27 for details.
The LED lights orange while the projector is in standby.
• If you press standby again within 15 minutes, the projector returns to normal operations immediately. The LED changes from orange to green.
• If you press standby again after 15 minutes, there is about a 60 second delay before the lamp turns back on. The LED flashes green while the lamp is re-lighting.
• If you don’t press standby again, the lamp turns off after 15 minutes. The LED lights orange while the projector is in standby.

PJ-TX100 Projector won´t start up out of Stand-By


Hi Mario

If there is no response on the Projector it normally means that the Mainboard is faulty.

Check if your machine is still under warranty because this quite expensive to replace.

As far as the schematics are concerned - I'm unfortunately not able to help you out with that.

Hi there

This could possibly be your Ballast ( lamp's powersupply ) that is faulty.

It will either need repair or replacement.

Green light flashing and then shuts down


Hi Gary

Have you resetted the lamp timer ? It must be done when a new lamp is inserted into the unit.

You can reset the lamp timer by holding the up arrow key on the Projector in until a online message appears. Then just follow the on-screen instructions.

If the problem persists , you will have to replace the Ballast wich is the lamp's power supply.
