I have a Benq w710st DLP projector and when i turn the power on after a minute it turns off. The power button turns off and both the lamp and temp lights turn red. How do I fix this and can I do it my


New bulb is probalbly needed. You need to find out what zero means on that projector. The real problem is finding out why the cooling fan is not turning on. This is probably the reason that the temp light is coming on.

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

All the lights are on: power light, lamp light and temp light... How can I fix it?


If you have the manual you can look at the back for troubleshooting. The problem or solution will depend on if the lights are blinking and what color they are. The manual can be found here. You will want the basic operations manual.

I just had a XJ- S41 projector in for repair because it wouldn't power on. The power light was red solid but the temp and lamp lights were blinking red. Apparently a reset was needed, but I was told it was an internal reset that had to be done be a technician. I'm dubious of this info as I've seen some reset procedures listed on this site that may have worked, but I can't confirm as I sent it in. It cost $45 plus shipping to have Casio do this reset and there was nothing wrong with the projector or any parts replaced. Casio wouldn't tell me exactly what reset procedure was done and they will not let you speak with a technician or even try and get more info for you. Using their online repair service though was easy and swift. Just go to www.ecasiorepair.com.

Projector shuts off after about 45 minutes


Just a long shot, but...

I have an epson 9000i that did the same thing. Turns out that unit has a small fan (I think 60mm) right next to the power supply to keep it cool, in addition to the large fan that exhausts past the lamp. The fan runs non-stop as long as the unit is powered-up for two reasons I can think of - keep the power supply a little cooler, and the lamp a little warmer so there's not such a temp difference when it powers-up. Long story short, that fan had died. I replaced it with an aftermarket 60mm fan and it's been working fine ever since. Hope this helps.

Both Temp and Lamp lights blink red


All you should need to do is go to the menu on the projector, and find the Filter Timer. Hit the right arrow to select the filter time, and then hold the rest button on the projector until you are prompted to confirm the reset. Hit menu to confirm and it should now reset the filter timer. Now cut the projector off and back on and the lights should stop blinking. I hope this helps.

Projector lamp flashes and the temp red led lights.


Purchased our76C in Jan, 2007. It is our second unit now that has had the same symptoms. When the unit starts up, the Power light is steady green as normal for a few minutes, but no image is projected. After a few minutes the lights do as you described. Both times Epson support authorized a new unit to be shipped out immediately. They said they had no known issues about it and didn't indicate what was causing the problem. Apparently it is not just the lamp wither. Also, the lamps both had under 20 hours on them.
