Optoma hd72 bulb turning off

My machine is 3 months old with 970 hours on the bulb. The bulb turns off after 30 seconds, no LEDS. Machine keeps running. I've tried repowering, removing bulb, same problem. Thanks, Mike

    After storing my Optoma HD72 in its original packaging for the past year (after moving), I carefully set it up today. It starts up fine with an excellent picture, but then to my disappointment the bulb turns off after about 30 seconds, with no other indications. The “ON” light indicator remains solid green and neither the “Lamp” nor the “Temp” LED’s illuminate. The lamp only has a few hundred hours on it and again the “Lamp” LED does not come on. I tried taking the lamp out and carefully reinstalling it, but the results are still exactly the same.

    I have an optoma hd72 with 1190 hours on the bulb. On two previous occasions (and now this, the third), I have encountered a problem with the lamp turning off from 15 to 45 seconds after the startup screen has cycled thru and the initial DVD images begin to show.



    My lamp and temp lights are both off and I have "re-synched" the projector, re-set source. Neither of these maneuvers has corrected the problem.



    On the two previous occasions this happened. The projector went back to functioning normally after some 5 - 7 days?!!



    I am less optimistic this time (pun intentional).

    Projector goes dark after 15 to 30 seconds regardless of video type and source. Bulb has 1100 hrs.

    i had the same problem i send it in and they fix it but then the problem reoccurs about 3 to 6 months later....I hate this projector and my warranty has just run out. I have had it back to optoma 4 times...

    Same thing: bulb turned off after 30 seconds. Tried vacuuming, blowing canned air, removing and replacing same bulb, which all involved removing power, which I thought would reset factory settings. After seeing the suggestion for resetting from the menu, I tried that, turning lamp brightness off, and now it works. Turning brightness back on, makes the fan come on, and bulb go out. Thanks!!!

    Same here, shuts down after 30 secounds. Have blown it out. still shuts down. doesn't stay on long enough to get the menu to the point for resetting. sounds like a design problem from here.
    mine has been running about 18 months.

Just so everyone knows, This projector is notorious for the iris going bad. Which causes the projector to just shut off randomly. You will have to send it in for repair.

My Projector is 6 months old and now it does not power up. When I press power switch on remote, the projector fan starts and red Led Blinks, but after a while the Led Become Solid Red and fan is switched off. No Picture comes. What could be the problem?

This is NOT a bulb problem unless your "lamp" LED is lit, which you say it is not. Many people have reported this problem with the Optoma 72. You can send it in for warranty service (it has a 2-year warranty) to get the lamp controller chip replaced, but the problem may recur. Optoma does not appear to have a permanent solution to this problem. My projector has broken exactly like yours TWICE in a year. I haven't even needed to replace the original bulb yet. :(

Same problem for me 16 months old, 1100hrs on bulb still under warranty.
Unit shut off after approx 90 seconds.
It continued to do this for 6 days straight.
On the 7th day I wiped the projector lens clean and have not had a problem for past 2 weeks.
I am a smoker so I am guessing the smoke build up on lens caused heat build up that triggered the shut down.
I will continue to wipe the lens before each use.

This is what the bulb does at the end of it's life. After replacing my bulb i have had no more problems. You can try to get by until your replacement bulb arrives by restoring to factory default settings. This will put you back into economy mode. This got me about a weeks time.

How do I put my WFW94HE Whirlpool front load washer in diagnostic mode?


For Duet washers, including the WFW94HE, you need to make sure that the washer is plugged in and turned on. Make sure that it is in standby mode (not running a program). (If you just turned on the machine, wait at least 30 seconds before continuing.)

Next pick any three buttons on the control panel, excluding the power button; you will need to keep track of the order that you choose. Then press and release each button and repeat the sequence twice more in 8 seconds. (The sequence becomes: press and release button 1, button 2, button 3, button 1, button 2, button 3, button 1, button 2, button 3 quickly.) If it works, you will see all of the control LEDs light up and 888 on the time remaining LCD screen. Note: the washer will exit the diagnostic more if no buttons are pressed in 5 minutes. You will use these three buttons to work through the diagnostic tests so make sure that you remember which one is which.

If this sequence doesn't work, turn the washer off and then back on. Try again with different buttons. (It's possible that one button is malfunctioning.)

I hope this helps.

Philips Gogear Connect 3 8Gb runs out of battery in less than two hours.


I had the same issue. Device would charge in 30 minutes, but would then die in about 40 minutes of playing music.
Solution in my case was to reset. The first time I tried the reset I did it with the device off and that didn't seem to work, the second time I did it with the device on and it worked great. The device showed 8% battery life remaining. I reset and turned the device back on and it showed 93% battery life remaining!(I did not charge it) Since that time I have been playing music through Bluetooth to some remote speakers and still have 91% battery left.
To reset get a pin or knife and push in the small reset button on the non button side of the device.
Good Luck!
PS - If you don't own a Phillips GoGear Connect 3 DO NOT buy one. This problem aside it is the worst mp3 player I have ever owned. And if you subscribe to Rhapsody THIS IS NOT RHAPSODY ENABLED.

Door will not open after cycle finishes


I had similar problem, but never found the cause, ended up spinning washing again and again until I could open door. Control system replacements are expensive , almost as much as a new machine.

No water comes out on ventilate. At first, the water was coming out very slowly, in drips. The doser or grind were not the problem, because even when I switched to Hot Water, it was still dripping. ...


Hi
It should take about 45 minutes to an hour to properly descale the machine. If it only took a couple of minutes you really didn't descale your machine. If you used the powder it has to disolve completly before descaling. The best way to descale is with the descaler in the tank. Turn on the machine and run about 8 ozs of water-descaler through the wand and then turn off the machine. Wait 10 minutes and repeatthe last procedure. Do this until the tank is empty. When done with the descaler, rinse out the tank and put fresh water in the tank and run the whole tank through the wand. Then fill the tank and your ready to go.

It sounds like the drum may be stuck. Turn the dryer on with the door open, just keep the button pushed. Then try to turn the drum by hand, and see if it will start to turn.

Hotpoint Washing Machine (W540) stopped working, LEDs flash....?


You must get the filter out, as there is a very good chance that this is the prob, keep unscrewing it and try to move it about, then screw it back in again , and then out again, hopefully this will dislodge whatever it is that is holding the filtter in.
Plz rate thiese comments.
Thanks.

Aml 125 washer - washing for hours


i would never suggest working or attempting to work on a machine covered by guarantee but this sounds like there is a fault with the heat cycle, obviously the machine keeps tumbling until the heat reaches the right temperature, with a heat fault it will not advance, to test without removing screws etc, press any heat option button like economy or turn heat dial to no heat etc, see what happens next. hope i have helped, if so rate me please, please note most engineers know if a machine of that age has been worked on and this will void any guarantee
