Optoma HD27 DLP Projector Repair / No lamp ignition
Вставка
- Опубліковано 24 чер 2020
- This HD27 was sent in by a customer from my day job who was unable to get the lamp to light. Optoma wanted $198 just to put it on a bench plus the repair. I found that piece of the OEM lamp glass had chipped off under a mounting tab and gotten stuck in the lamp fan. Removal of that glass bit allowed the fan to run again and which allowed the lamp to light.

Hi Frank, well come after a long time presence.
Bom dia! Vídeo foi muito útil para mim, pela suas instruções descobri que o problema do meu Optoma HD28DSE era a lâmpada queimada. Obrigado, vídeo muito bom.
Thank you for your video, your video helped me solve my problem!😊
Thanks for these videos. Just replaced the bulb and color wheel on my hd27 to fix both problems. However now I see fuzzy white specs on a dark/black image that I can't seem to be able to blow/shake off. Did I dislodge some dust?
Hey Frank can you do a video on cleaning the dust out of the lens of any Benq projector. I have tried to clean them but no joy. After cleaning the mirrors and magnifiers in front of the dmd chip still dust is there. the dust disappears when focusing the lens but as soon as you turn the lens out of focus they appear. I did not clean the dmd for fear of damaging it.
Great video! Hey Frank I have an Optoma DLP Projector (black) it has a power but the lights are not showing off, can you advise if this require a bulb replacement? thanks!
Hi Frank, hopes you and your family are all safe. Thanks for another great video, fine repair . Can you provide a link for the russia guy you talked about? Have a nice day, kind regards Peter.
HELLO FRANK This malfunction liquid mercury lamp entering between main and cathode moved and mercury was released. Electron continued to flow.
I've got an Optoma X600 Projector, I only use it a few times a year. No longer fully powers on. Power light blinks 7 times, pauses, 7 again, and repeats. Google search points to a Lamp Door Sensor, but I cannot find any schematics on how to address that. PC Detects the Audio signal from it, and web-interface of the projector says "No Errors", so i doubt its the board. Any thoughts?
👍 frank ... Lots of people go heavy on compressed or canned air and knock off cw sensor... Also seen fried fans from spinning too fast backwards due to overzealous Clint Eastwood(on meth) with air gun. Sure you've seen it all.
Hey fix it frank I am having a problem with my projector. The projector comes on and runs and I replaced the bulb but before I did the light went out. Like no picture, before it completely went dark the colors were off like yellow was green red was brown etc. New bulb still no light or picture. Color wheel still clicks and fan still runs but bulb light comes up red and power like turns orange but the projector still running
Kind of sounds like you ended up with a defective or low quality bulb. If a new bulb gave you flickering and offset colors, that is a symptom of a cheap housing. They will cause the color wheel to get confused and shut the projector down and even prevent it from lighting all the way.
I have a link in that description box for a bulb that is good quality. I doubt the projector is broken at this point,. I bet its a bad bulb.
Hello
At my optoma hd 29 darbee the red colour became orange and after I got lamp problem but lamp is good
Could this be the mainboard? And if where can I get one?
Haver you ever fixed an HD27 with a "Fan locked" error? I replaced both fans. Still get the error.
That is annoying. I would check the status output of each fan and see if one isn't working. I have a video on testing fans that might help. It's possible something on the main board has an issue. The fan control IC might be bad or the pullup resistor for the fan status lead. Also check the solder on the connect.
Hello - I have an HD27. When I press the Power button, it initially goes blue. But then after a couple of seconds, the lamp LED shows red and the power button begins flashing red. I had tried to reset it by unplugging all the cables and then holding the power button down while inserting the power cord. Then the power LED began blinking quickly and then I released. Then I read to press the Power button again and there should be a "click", but mine never did and eventually the Power LED went back to red. I have yet to resolve the issue. There is no fan that comes on when I try to power it on. Any assistance would be greatly appreciated. Thank you!
Hi, i can't find anywhere whats The DMD chip model for This projector. Could you help me?
That's a tough one. Personally I always remove them and get the number so I am 100% sure before ordering. Being that you have to remove it anyway I would suggest that. Sometimes the online info is incorrect. One other suggestion is to call Optoma. They won't have it in stock but they will likely give your the part number. Their repair service is poor but their parts service is pretty good.
Any idea on why an optoma hd144x has all 3 leds lit up. power red/ blue leds lit, lamp and temp leds are red? Just turned off with less than 70hrs. No other signs of life!!! Will have to leave in somewhere local as unfortunately your to far away. Thanks for the videos
without seeing it I am guessing but I would be suspect of the mainboard being bad. I can't really say what is bad on the mainboard but if I had to guess, it would be a voltage regulator as they are a common problem. Another possibility is the power supply. This sort of problem is usually pretty terminal. A replacement mainboard is in the $300 range. If you have any local techs who can check it, they want to verify the low voltage power supply first. If that checks out, then check the little voltage regulators on the mainboard. Let them know the PMD1000 IC is a known culprit as well.
@@FixitFrank thank you, I appreciate that you responded and shows that you are motivated to online education via your videos. I havent seen the fault reported anywhere else online. I'm a physical therapist, so not my area of expertise and would only go as far as testing capacitors fuses, mosfets. I will leave it in and if they can fix will update on the cause in case it helps yourself or someone else. Many thanks again Frank.
Awesome video im just about to start looking for a replacement bulb cause mine isnt to bright anymore but still works, is theres any blub you recommend now
I like purelandsupply.com if you are in the USA. Use code yt50 for 5% off
@FixitFrank thanks so much what a difference after a few years of same light. Looks amazing. I tried to get my 2nd projector working but I think it's messing up. Do you know of a place in southern California where they would take a look at my projector
Hi I have a UHD35 that had a big lamp blown. I had to replace the power supply board because it was burned. I have also replaced the lamp but when I turn the device on it shows the optoma logo but after few seconds it goes off and I get blinking red light for power and fix red light for the bulb. Do you know what could it be?
its hard to say on that chassis. I'd see if the color wheel is okay. Also if you replaced the lamp assembly with a cheap one, that can cause it because they use the wrong IR filter on the housing. Make sure the lamp has a red/blue tint to the front glass. If its green/clear that is your problem. If not, then it might be a mainboard issue.
@@FixitFrank thanks a lot. Really appreciate your response and your videos all of them very instructive. I'll check about the lamp although is a Phillips one. I think it might be the color wheel...hope is not the main board. I'll let you know when I get it sorted. Again, thanks!
I dont mean the bare lamp. I mean the full housing. see this picture. imgur.com/i4eyOKE The part I put the box around is what you want to look at. If the lamp assembly was from Optoma then it will be okay but if you bought it on amazon or from some of the bottom feeder aftermarket websites, that could be the problem. h
Hello I have a optoma gt1080 3d dlp gaming projector and I replaced the bulb the color wheel spins and so do the fans the only thing not turning on Is the lamp and everything seems fine can someone help me please.
Be sure the bulb is a decent quality and not from amazon or a discount bulb company. I see so many of those ruin or damage projectors. They will also not light or cause a shut down problem.
Hi Frank, I've had a similar issue with an Optoma HD26 but still got lamp light after clearing all the glass debris. I've posted on r/projectors but no responses
Hi George! These have an integrated power supply/ballast that can be "electrically fragile". ua-cam.com/video/SU89j8NoyBc/v-deo.html See this video on the GT1080(short throw version of the HD26 I believe). They are identical electrically and this projector had an issue where the lamp would light occasionally but mostly not. Ended up being a problem in the Power module. Did the lamp burst while it was on?
@@FixitFrank Yeah it did!
Sometimes that can damage the ballast. The lamp will touch the arc points briefly enough to short out and damage the mosfets.
Are you able to post a video of the projector as it operates now? If I can listen to the attempted start up, I might be able to see what is going on.
I was cleaning my Optoma hd70 but now I’ve got vertical black lines, is it the ribbon cable?
I'd suggest reseating the mainboard again. That is likely the issue.
@@FixitFrank thanks, that was the problem.
I fixed my color wheel which was missing a chunk, and I also replaced the bulb. Now the fan doesn't even go on and there is just a light clicking sound and the projector goes into red dot lamp failure mode. Seems like things have gotten worse after replacing the color wheel. I have an HD28DSE. Any advice? Thanks
Did you replace the wheel or just glue the chunk back in? It could be the wheel you hear clicking. The wheel must spin up before the lamp will ignite. If you didnt replace the wheel, I would do that first. Usually once they throw a segment, they are pretty done. Sometimes you can recover them but its rare that it works.
@@FixitFrank Thanks Frank, it was that I didn't trick the switch on the lamp cover. Silly mistake. Everything worked after that, but I did accidentally remove one of the screws holding the mirror box in the light tunnel so I had to spend an hour adjusting it to remove the burn on the screen. I ended up getting it 90 percent of the way there, but I need to find the right mirror box for the OptomaHD28DSE light tunnel and replace it, because there is still a few inches of burn at the bottom right side of screen that I cannot seem to adjust away.
Hi Frank, I have a optoma uhd 60 and it is not turning on. Wondering what problem would that be
That's a tough one. The UHD series has been a real lemon from Optoma in my experience. When they work, they're awesome. Great picture and brightness. But when they break, they seem to really break.
Is it trying to come on? Any LEDs or fan noises?
Any one doing professional led conversions for DLP projectors (take out bulb, replace with LED)?
Hey Frank! Hoping you could direct me in the right direction. I have an optoma hd26. Was watching a show and it turned off. Power/standby is solid red. So is the lamp light. When I turn it on The light goes blue and there is a click noise. about 3 seconds later the power light goes red again and the lamp light turns solid red.. the fan doesn't start up at all and neither does the color wheel. I tried a new bulb just to see and it didn't fix it. The projector has maybe 500 hours on it. Surprisingly little info about it out there. Any help is extremely appreciated!
. I have a few vids on this chassis. Look up my video on the GT1080 I did recently. They use very similar chassis. In fact my own HD26(which Im selling) had a similar issue and the power supply ended up being the culprit. I have a few videos on the HD26 but they were color wheel vids. They do show disassembly though.
@@FixitFrank right on! Thank you for responding to me.Based on the description you think the power supply board is most likely the culprit? With these older projectors I don't wanna sink too much money into . Sucks tho because it really doesn't have a ton of hours on it.
@@FixitFrank also...what kinda price would I be looking at to have u fix it?
It does sound like it. Of course you want to do the troubleshooting to be sure. I only say the power supply because it seems to be a issue that pops up with other models with the same symptoms.
hey frank what do you do is the color wheel dosent turn but the fan runs....that what im getting on my hd20
Hi! I would suspect either a stuck color wheel(bad motor) or possibly a problem with the mainboard and the color wheel driver chip. If you never changed the color wheel before, I would suspect that first. My HD20 is Color wheel #2. (it's about 9 years old)
@@FixitFrank it was the color wheel sensor....i switched it with my identical one....i got two...now i fix that one now the other one i put the good color wheel and sensor on it and now it dont even turn the fans on i pushed the color wheel a little and it jumps and thats it then the red lamp lights turn on any solution for that?
Id check your color wheel sensor wire on that one. I bet one of the 3 wires is not connected (it may be glues in place so it will look connected).
I have to ask because this just happened to me my wife called to tel me she went to turn on the projector and the screen came
Down but the lamp did not fire.. later the lamp failed lamp lit up.
So I get home change the lamp same thing however I noticed the color wheel sounds a bit louder when it spins can dust get on the index mark to prevent it from starting?
Not the index mark as much as the sensor for the index mark. Since its spinning dust tends to not attach to the hub, but since it is spinning, the mark can fly off. The dust can land on the index mark sensor. I'd check the lamp assembly first. If its older(1500+ hours) I would try another proper new lamp assembly first. If its fairly new(less than 1000 hours), then check the color wheel area. Bad lamps are always my first suspicion since its the most common problem, and then I troubleshoot from there. If you want to post a video of the noise or check the short I posted with a bad color wheel noise ua-cam.com/video/TEnXuTeZjIw/v-deo.html (same chassis as the HD27).
@@FixitFrank you can see the video I did last night I checked the color wheel today no missing segments.
The bulb only has about 700 hours on it
ua-cam.com/video/34BGkUuc5FQ/v-deo.html
It sure sounds like the index mark came off. That 'dit dit dit' noise is the motor speed adjusting to try and pickup the sensor. See if that black sticker came off the hub. The segments should be ok (like you noticed). I suspect the index mark fell off. It's a common problem on this chassis. Or the index mark sensor is acting up. The noise tells me that "something" with the color wheel index mark is the likely the problem. You may get away with regluing the index mark sticker back onto the hub or just replace the whole wheel. They are pretty inexpensive.
@@FixitFrank thanks I took the bite and just ordered the color wheel should be here tomorrow so I will keep you updated on it.
@@FixitFrank you were 100% right Took this photo, new CW is in and all is well again! Thanks so much for this video and the help!

How do we contact you?? Would love to pick your brains about an optima x605 possible ballast issue!!
on my about page there is contact info! Thanks!
Where’s the best place to get parts?
It depends on the parts. There is no single source unfortunately
Hi Frank, i just bought a second hand, like new optama GT1080. When starting up i have a red power lamp, when i start it it turn blue. Than i hear a click. Then nothing. Bought the lamp indicator and the power lamp turn red. Lamp looks brand new, colour wheel is perfect. I hope you can help me out! Best regards from the Netherlands
Cheers Alfons! That sounds like it might be a power supply issue. Do you get any fan noise?
No i can not hear the fan Frank. Do you know how i can fix it?
Hi Frank, I am getting lines on the screen. Optoma HD 67N. Any thoughts? Thanks
What kind of lines? vertical strips or moving horizonal?
@@FixitFrank vertical strips
Probably a loose/insecure connection between the mainboard and the DMD board. That is a pretty common symptom. Double check the screws in that area.
Do you know anyplace i can take my projector for repair or do you provide that service its an Optoma g720..black lines appear after trying to clean it
I think if you reseat the mainboard you should be OK. Usually that is bad contacts between the dmd board and the mainboard.
Ok thank you I will try again..when I took the screws out 1 screw was a bit longer and couldn't figure out were it went.any idea
@@map1537 What kind of screw? Is it fine thread or coarse thread?
I can't tell the thread looks the same I think I got 3 tiny screws and about 15 that are the same and 1 screw that is a tad longer than the 15 ones.. I shouldn't have tooken it apart im not near qualified . I put it back together can't see where I went wrong
Hey Frank- I have an Optoma GT1080 that doesnt work- power led is flashing amber, and lamp led is solid amber- could it just need a lamp replacement? Or any thoughts on a fix? Thanks
Or how to contact you if it is possible to send you the unit and help fix it?
Hi Allen, When was the last time you changed the lamp? The error you list does point to a lamp issue. I usually suggest trying a lamp first, only because it is the easiest solution most of the time. Plus you can return it easier if its not the solution.
I suggest a new lamp first. Make sure its a reputable brand or comes from a reputable seller. Amazon is a cesspool in my opinion for lamps. eBay is actually safer in my opinion. Otherwise, if you are in the states, I suggest any company on this list. They all sell decent quality lamps that will have the proper IR filter lens that most of the Amazon lamps do not have. www.projectorcentral.com/projector-lamp.htm I'd buy from whoever has the best reviews and best prices.
If the lamp does not solve your issue, feel free to reach out. My email is listed on the about page. ua-cam.com/users/FixitFrankabout
@@FixitFrank i have not replaced it yet- so i will give it a shot first and reach out in case it doesnt fix the issue. Thanks!
@@FixitFrank Hi Frank- I ordered a new lamp from Pureland supply and that did not resolve the issue. So i guess its not the lamp. I will contact you as I am hoping you can help resolve the issue. Thanks
@@FixitFrank Not finding your contact info at the about page. Is it the sales@weezytech.com? Thanks
Saludo tengo uno igual no enciende ningún led que podrá ser
I like what you do there with that proyector,now my problem is a DBpower "new",it plays just a few minutes,I test everything and it's start to smell like something burn and shut off and now don't have any image,but it look like it have electricity,but do nothing else,can you have the time to tell me what is it?,I appreciate your help ...🥺🥺🥺
I check some videos showing me it can be the SR5100,help!...not of the fan are working and the light from the lamp is like flashing.
It's a DBPOWER L21 mini LCD video projector....🥺🥺🥺Thank you,sorry for my English!
"New"for the year it came out,but new from the package... 😏😏😏
Your english is fantastic! No need to apologize. Unfortunately these are surprisingly low quality devices. The polarizer film and LCD panels always burn at some point. My personal feeling is that the manufacturers of these do that intentionally to make people buy new versions.
I would suggest looking for a used name brand projector(epson, optoma, NEC etc) as they will last far longer. You can find an older used beamer/proyector for less than $100USD and even as cheap as $20-30USD. I would stay away from LCD versions unless you can view an screen image first. old LCD can have a spot in the middle that is not repairable. DLP/LCOS tend to hold up longer.
@@FixitFrank Thank you for the suggestion,so you are saying the I better buy something else,don't botther to fix it!....🥺🥺🥺.
Even if I replace the diode or the lamp is going to keep a mess up product....😬😬😬,better buy a new and different projector!?... 🤷🤷🤷😅😅😅
@@FixitFrank You should see how beautiful picture have,that one of the reason of buy it on the first place.It is posible to change those part the you mentioned and keep my "new" projector?...😅😅😅😅
I would not suggest repairing it. These are designed to fail. Plus the cost will exceed the value of the projector. A used name brand projector will serve you better and longer. I wont even take these in for repair because of how they are designed to fail. the companies who make these, use parts that fail intentionally so they can sell you more projectors. They skip things like fuses and extra fans and heatsinks that would help the longevity because they want you to buy a new DB power every year or so. I'd look for a used Optoma HD20, BenQ W1080, W1070 or Mitsubishi. they will treat you very well!
where is the fix? this is a cleaning the title suggests you diagnose an issue and repair it. Im not getting lamp ignition. the lamp appeared to be working then the color wheel was noisy. the lamp doesnt seem bad, but the base does look chipped but no debris inside. no lamp ignition at all after color wheel replacement
The repair for this was a cleaning. That is the fix for that particular projector. I say that in the video description.
From what you commented, its probably something to do with your color wheel replacement. What specifically I can't say. Numerous things can cause no lamp ignition. Best I can offer with the info provided is go over your work and see if you missed something or re-assembled something incorrectly. There is no one cause.
If you don't place the cover back on or trick the switch, neither fan nor lamp will go on.
hey franc can you write your email adress? i have problem with optoma hd141x thanks
Hi Frank, I have a similar projector the optoma hd142x and the bulb won't ignite neither, but the power works and I can turn it on and after the colour wheel spun 3 times the red lamp led flashes. I replaced the bulb but it still won't ignite, so I took the projector apart and checked everything, the colour wheel, the optics and the fan but everything worked. Could it be the power supply or even the main board? I hope you can help me.
Your videos are great by the way, helped me a lot so far.
I am
Having the same problem please let me know if u find any solution everything is working but lamp not igniting
Having the same problem since a few days now. Did you find a solution?
@@lackoo123 yeah, I replaced the power supply and so far it works great. I bought it on ali baba or Express, I dont remember but the name of the power supply is AIO 203g C/T25. But don't take my word on it, i don't know if you are having the same problems as I did.
