Hello,
I have an Optoma projector and the power LED is blinking 7 times in a row which means (according to the manual) "Lamp door sensor detects high." What does that mean? How can I fix it?
Thank you very much!!

Hello everyone,
I had the same problem, the clip holding the blue switch had broken. It's just a simple switch, but what is it for???
I did exactly what Toto did and it works. I took about an hour to remove the metal cover on top of the projector, took out the cage containing the bulb (be careful, you need to remove the flat cable between the control panel and the circuit board by lifting the black part that tilts up), removed the switch with the blue clip, cut the wires by short-circuiting them after stripping them (don't forget to put a piece of tape to insulate)
Good luck, it's easy to do thanks to Toto.
A big thank you!

Hi,
I also have the same problem with my Optoma ES520. I unscrewed the plastic cover, unscrewed the small aluminum plate that protects the circuit board. Behind the lamp housing, I spotted the little blue pin in question. Indeed, the plastic screw that held it had given way.
I then removed the lamp and pushed the blue sensor into the lamp housing for easier access. This sensor seems to behave like a simple switch; with a tester and a piece of tape, I kept it in the closed position and pushed it back into the device without caution.
Good news, it works!
Yay and thank you!

Maybe the lamp is faulty. This is often the case. It is the most sensitive element of an LCD video projector.
I accidentally came across your comment about the sensor of the Optoma ES 520 projector, as I have the same problem as you. Your comment was:
"Good evening, well it just happened to us... well we disassembled it and "shut" the position sensor!! there you go bye"
Could you tell me what shut means? I don't know how to fix it.
Thank you so much for your response. Otherwise, it will be customer service and I can sense a hassle coming. I bought mine at Auchan.
Thank you for your response,
Best regards,

Hello everyone! Thanks for this post, I had the same problem: the green light blinked 7 times, I took it apart, the support for the blue switch was broken, even though the projector stayed on its wall mount for a year without moving!
I glued the switch with super glue and it works again!
So there is a manufacturing defect at this level!

Hello,
I have exactly the same message with an Optoma ES520.
Have you managed to understand the meaning of the message "Lamp door sensor detects high," or even better, to solve the problem?
Thank you

Yes, it's the sensor of the plate under the video that holds the lamp; you need to screw it back on tightly, but for me, it didn't change anything. I contacted Optoma, and they replaced it for me (big hassle, but I didn't pay anything). Be careful if you send it back, mine broke during transport, but I managed to send it back. Go to the Optoma website, find the customer service form, fill it out and send it; then they'll send you your video.
Is it not working at all? What happened?

Since I live far from France, I eventually opened it up. The sensor in question is a small black round piece fixed to the chassis with a screw. It was the mounting part of the sensor on the chassis that had broken on my video, certainly due to the strong pressure from the return spring, so I short-circuited the sensor in question and closed the case. There you go, since then it works wonderfully without its sensor... obviously, opening the case made me lose the manufacturer's warranty in case of a problem, but in less than 20 minutes the video was functional again...
It's been a while now, I don't remember very well...
Off the top of my head, the lamp's socket has a prong that presses on it.

I solved the problem. The sensor in question is located between the printed circuit board and the metal cage that contains the lamp of the projector. The bracket (where a screw is normally installed) that holds the blue tab had indeed broken. Probably due to the spring. To fix the issue, I rigged up a small device to position the blue tab as it was before (when the screw was there). And miracle, the error message (7 green power LED blinks) disappeared and the video turned back on!!
< p >ME TOO, I JUST HAD THE SAME PROBLEM EXCEPT THAT MY BLUE LEG HAS NOT BROKEN AND EVEN CHECKING ITS POSITION, MY VIDEO DOES NOT START ANYMORE.< /p >
Thank you very much... I had lost the warranty and thought it was good for the bin. Let's get a movie at home...
Congratulations to all of you, I confirm that this malfunction was repaired at my place as follows:
remove the bulb, take off the cover, remove the metal plate, see the little blue switch (with a small blue tab that turns), remove the blue switch previously passed through the lamp cage, cut the two wires, join them together, close everything up, and after a big prayer... it works :)
well done, guys!!!!!!
P.S. the little blue switch in question is visible between the circuit board and the metal cage of the lamp, there is a gap of about 1cm where you can fit a screwdriver or even a finger and pass the little switch into the cage through the rectangular hole.

Good evening, I have the exact same issue with the power indicator blinking on an Optoma EW1610. If I remove the lamp, open the cover and the aluminum plate, I can't reach the blue switch because the fans prevent me from accessing it, and it's impossible to disassemble them. Does anyone have an idea, please?
Sure! Thanks guys, I would never have managed without you.
For the artist, just a little clarification (if the project is designed the same way because mine is an ES520): try to pull the switch towards you with a screwdriver or something else (if the mounting is broken, the switch should be moving around in the space between the cage and the circuit board).
Once the switch is free, you can force the position with tape or by disconnecting the switch and connecting the two wires as I’ve read. After that, put it back in the space where it was and then reassemble everything (do a test before reassembling just in case)
Good luck! And thanks again to the others.;-)

Thank you very much to everyone, I succeeded tonight without any prior knowledge! Thank you thank you
Hello,
I have the same problem with an ES 520, the attachment of the blue thing is broken, but I can't seem to access it... can someone provide me with more detailed explanations... I can't access the circuit board.
Thank you in advance.

Hello everyone... and a big THANK YOU! for these precious tips that helped me get out of a tricky situation, since this video projector wasn't mine!!
Indeed; 1) I unscrewed from underneath and unclipped with a flat screwdriver the plate where the controls are located. 2) I unscrewed the plate underneath the projector to access the lamp and removed this lamp with strong pressure from the contact side (male-female) of the lamp by pressing with my thumb on the black plastic chassis. 3) I unscrewed the metal plate on top of the printed circuit. 4) I unscrewed the lamp cage, taking care to remove the lamp's fan on the side *(if you don't have a magnetic screwdriver, rub your tip several times on a simple office magnet, and WARNING: do not damage this small transparent plastic disc facing the lamp!) 5) you can then see this small round black switch with a small blue rod at its end activating a small spring inside it. 6) the simplest and most effective way is to cut the red and black wires as close as possible to this switch and strip them from the plastic sheath for 1 cm, then twist them together. 7) VERY IMPORTANT: reassemble the device completely before turning it on again.
THANK YOU and good luck to the unlucky ones
Best regards, JCF

I have the same issue with my Optoma 759, the POWER light is blinking and moreover the touch keys on the cover are not working anymore.
Can you tell me exactly where the part to be modified is located, is it in the lamp cage?
Thank you in advance.
