Last Ditch DLP Color Wheel 'Fix'
Вставка
- Опубліковано 4 жов 2024
- I say 'fix' because this has a very small chance of working long term. This is a possible way to get your color wheel running until you can get a new one installed. Occasionally it will fix it for a while, but usually it will get you a week or less. Usually not at all, but at this point, you have nothing left to lose. Be careful, the glass is sharp. Thanks for watching.
DLP TV’s were great for their time, they had a nice area of view and no burn in, amazing brightness and every time you replaced the lamp it was like you had a new TV. Unfortunately, too many moving parts, color wheels failures were common as well as unexpected lamp failures. Back in 2003 I paid $5,300 for my Samsung 65” HLN and that was a great price. The picture quality was amazing even though it at most it was 1080i. I repaired it myself numerous times until it just wasn’t worth repairing anymore. I replaced it last year with a 4K LG 64” OLED for less than half the price of the Samsung. This TV is simply beautiful. Can’t wait to see what’s coming next.
OLED. The LG roll up TVs are what I am waiting for the manufacturing to get cheaper.
thank you . your video prevented me from buying more unnecessary parts and the tv
works fine.
Thanks for letting me know it was helpful for you. I'm glad it was able to help. Thanks again!
Thx, just saved me $80
very useful video
Have an Optoma hd151x, which had problems with the wheel after 10.000h, making strange noises when changing frequency, sometimes losing sync and shutting down. After desperately cleaning the sensor, it won't start up anymore. Luckily is saw your video. Cleaned the wheel with lots (much, much more than in the video) of alcohol and used a very tiny amount of grease (from simple fat-spray, for bicycles). Perhaps no bad idea, to bath completely in methanol? After nearly standing still, it made 2-3 turns when accelerated with the finger.
Now the hd151x runs again and the wheel has stopped to make any rattles and pitches + better colors and i've the impression better sharpness.
I should have done earlier.
Thank You!
200 hours, still working like new. Thanks Again!
After 3 years and many extra thousands of hours it became dusty again. This time i did put it in a pot with alcohol for some minutes + air spray + a litte grease.
... runs again like a charm. IMHO 99% of CW-failures are caused by dirt in the bearing, accelerated by smoky environment. They should be sealed, too, else this is "planned obsolescence", because the main components of DLP-Projectors are nearly indestructible or easily replaceable, breaking the hearts of the marketing-department, eagerly trying to sell Fake-4K, with way worse contrast and saturation.
Biggest "experts" on this sector are Casio and their Phosphorus-Wheels often not even running 1000h without getting noisy.
Mechanically spinning colors wheels.... this is indeed a great technology.... right out of the 1920s.
I suspect they had clockwork wheels with candles or even oil lamps before that!
DLPs are great TVs. When these DLPs were popular, you could get a DLP in a much larger size for less than the price of their wall-mount counterparts. I have several DLPs and they're all still working fine. I've had to make a few repairs, but they're made up of discreet parts, so they can be repaired easily. Wall-mount TVs can't be usually repaired for less than the price of a replacement TV, so they usually get thrown in the trash and replaced with a new TV. DLPs can be repaired and keep going.
I had one 3LCD projector, it had so bad contrast and black color, that I switched back to this 20s technology. :-) And it had 2 fans and it was more noisy than DLP with loud color wheel, but I agree, it's really archaic technology, but 3LCD is not solution, it has really bad picture.
@@Pidalin I have a 3lcd projector and colours and whites are amazing but black levels are horrible. Images are close to what is displayed on my PC.
@@masterkc It's much worse than on PC, I have MVA LCD panel which has pretty good black color compared to IPS or TN.
Frank,
Thanks for all the great videos they are so much help to us all! I was wondering if you knew where I could find a color wheel for an optoma uhd51 I can't seem to find them anywhere it has 8 segments
Hi Clint, Just replied to your email.
Thanks for the tip frank it worked :)
hi, My Optoma ML 550 turn off automatically and its say fan failure , orange led blink , is it fan or color wheel problem , Projector made grinding noise , all fan spin without any problem and i already clean fan and heatsink
hello! I would check the smallest fan. If it says fan failure, that would mean the color wheel is okay. I think it is a fan problem. If you hear grinding that would make sense to have a fan problem.
@@FixitFrank Thank you for the reply. Already check all the fans. And all of them are spinning . Already cleared them and should I use alcohol to clean them or spray lube or contact cleaner?
have viewsonic 7820hd projector, when we start then after few minutes it starts flushing & then colors goes to inaccurate, my projector run 1900 hours, how to solve the problem? Sorry for my English it's not good.
Question sir , is it possible to use a different model color wheel of same diameter and attach to frame and harness? i have a section that broke and would like to repair just plastic piece... would colors need to be identical. FYI Using original photo sensor and frame.. just curious and you would know or done it .. .I'm sure it needs to be balanced perfect to work also.. thanks
The colors do need to be identical. The projector is designed to expect the colors to be in place at specific points of the image being displayed. You can use segments from other color wheel to replace the broken segment. I have glued them in and had it work successfully. However with the price of color wheels being in the $30 range, I tend to buy replacement since I also know the motor and bearings are in good shape. That said, I will use any color wheel that works, to test projectors. If I am not sure if the motor is bad or the circuit is bad, I will plug in any color wheel and it will spin. I wont install it but it tells me that the circuit is ok.
Frank, I just attempted to replace the color wheel in my Optoma DLP HD26 (similar to HD141). The original had horrible buzzing noise and it was definitely the color wheel. However with the new one in place, the projector turns on and makes horrible random buzzing noise much different than the original sounds like coming from the new one and the colors are like a rave/lightshow flickering really fast coming out of the projection. After watching your video it looks like my infared, or led next to the infared, may still be dirty not being able to monitor the color wheels rotation/rpm. You can hear the rpms go up and down on the color wheel. I am going to tear it back down and try to do it again. Any input on this? Have you heard of this before?
Hi Brad, It does sound like a problem with the color wheel index sensor. Did you replace the lamp as well?
Can I use WD 40 lubricant on TV Color wheel not spinning correctly?
Thanks
Probably not. I wouldn't recommend it. Ymmv. The mineral spirits in it may start to cook off and get all of the glass. I find the best option is getting alcohol inside to break up the crud. Gun oil might work in little drops since it is OK with heat and it it might soak back into the oil bronze bushing. That said, if its to the point to where its sticking, you want a new one. For a TV(samsung?) they should be pretty cheap these days. If you can get the hub apart from the stator, you can clean the shaft and that might sort it.
Hi Frank I Have the Optoma HD25e like 6 months ago suddenly the screen turn like dark Grey and a shadow of the last proyected image shown. I turn off and on the projector and worked fine but the error repeated several times. Until one day the lamp won't turn on and only the green light stays flashing. I open the unit and changed the lamp with a new one. Cleaned all the dust dessasembled almost all the components. But It didn't work I left the projector for 5 months. Then one day it turn on ok and work perfect for like 2 weeks then again the same problem happend and now the projector again won't turn on only Flashes the green light. Any advise? Thanks
That sounds like a color wheel to me. The stuck grey ghost image is what makes me think so.
Hi Frank,
I have a problem with my optoma HD70, when I turn it on it start normally but after 30s the blue screen turns gray and flash then the projector stops with the power and lamp lights on. I tried to change the lamp and clean the color wheel detector but the problem is still the same. Do you think I should try to clean or change the color wheel as on this video ?
By the way,thanks for your videos they helped me a lot to try to fix my projector.
Hi Flore, If you still have the original color wheel then yes. The symptoms point to the oil bronze bearing being worn out. Most HD70s are on their second or third color wheel by now. Believe it or not many companies recommend replacing the color wheel every 3 years...That is ridiculous in my mind but I can see their reasoning.
Hello frank, i have an acer X135WH projector with buzzing noise from colour wheel. Can it be fixed by cleaning the motor? Also, if i have to replace the colour wheel, how to identify which one to buy? Should it be similar model or any optoma/ acer/benq colour wheel will fit?
Looking for color wheel removal procedure for a Panasonic PT-56DLX25.
I have a ViewSonic PJD7820hd. Has 500 original lamp hours. When you first turn it on, it works great. After 2 minutes or when it reaches running temperature. The projector starts to flicker colors then shuts off with a red light on the lamp button. Color wheel is clean and spins freely. Cleaned color wheel sensors. Black marker tape visible on color wheel. Any suggestions?
Does this work on air bering color wheels? My Samsung has an updated air bearing instead of ball bearing and sometimes makes a loud vibrating noise but the picture is still perfecting . Why not use duster aerosol?
The sleeve bearings are frustrating. If it is making a vibrating noise, the bearing has failed. It is time for a new or used but still good color wheel.
My tv popped tonight so I checked the lamp. It's blown. There has also been a constant buzz. Should I check the color wheel.
Don't want to buy a bulb if it won't help.
Mitsubishi AD 73740
Thanks
You should check the color wheel. However it's going to be tough without a lamp. I'd buy a lamp somewhere that will take it back. Then check for the noise location. Might be a fan too.
Thank you. I ordered a lamp. I'll go from there. Not sure how much money I'm willing to spend.
@@lellyann68 I wouldn't spend more than a hundred, hundred fifty maybe... It's a good TV, but for not too much more you can get a nice LED flat panel. If the lamp doesn't solve it or if its not just a cleaning, I would put that TV on a craiglist/kijiji kind of thing. Or, take the mirror and screen lens out and make some neat solar ovens...
@@FixitFrank we looked at tv's last night. Can get a decent 65 for $500. If the lamp doesn't do it it's out of here lol
Hi, is it safe to carry DLP projector in check in luggage? please advise. thanks.
No problem at all.
@@FixitFrank thanks Frank, it worked 👍
Hey bud, got a wd-73642. Each time i turn it on after it sits, the color wheel makes a loud screeching sound till it spins for a minute then it quiets down. You think lubricating will help? Also would you have an idea where to get a new one?
I don't think lubricating will help. They rely on a dry sleeve bearing due to the heat of the lamp. Any lubricant will cook off pretty quickly. Once they squeal, it means the bearing is beat. Replacing them is not that hard though. eBay has plenty and as long as the seller has a decent rating, you should be fine. www.ebay.com/itm/USA-Color-Wheel-For-DLP-TV-Mitsubishi-WD73840-WD83840-WD92840-WD73640-WD73642/153344875410 as an example.
I need a new color wheel for a Acer P1185. Can you point me in the right direction to purchase one?
Hey Frank, I wonder if you can give me your opinion about an issue with my projector... A few minutes after I turn it on, it flickers a bit and the red color goes missing... then It stays without flickering but with a "green image", sometimes it comes back to normal but its being doing it almost everytime... I opened it and clean it completely, including the color wheel, and the wheel did not look too bad, actually it was not even dirty... what do you think it could be the problem?
Hi Pablo. What is the model #? That would help me figure it out. My gut says color wheel but it could be a few other things.
@@FixitFrank hey! Sprry i just saw this, its an optoma hd20
My tv is giving me code 61 which is supposed to be color wheel. But i bought a new one and its still saying color wheel. But the new doesn't spin freely like it should. It's likely the the new wheel could be bad to?
It could be. Is it a new color wheel or used but known good?
@@FixitFrank its new. But i put the old one back in and it work. I think the new one wasn't line up with the sensor
Would you say that a dusty wheel could exhibit an intermittent "growl"?
Definitely. A growl is a good description.
@FixitFrank - Interesting. I'm not looking forward to breaching the ol 72" Toshiba again and am also not looking forward to the possibility of the growl being a color wheel, but what I am looking forward to is getting the thing fixed once and for all.
@@Browningate could also be a fan. The growl is usually accompanied with some color shift in the picture.
@FixitFrank - I've not noticed much in the way of PQ problems that coincide with the growl. I'm hoping that it's just a cooling fan.
Is the Growl different, when you're changing the Frequency, ie. between 50 and 60Hz? If Yes => Wheel
Question sir , is it possible to use a different model color wheel of same diameter and attach to frame and harness? i have a section that broke and would like to repair just plastic piece... would colors need to be identical. FYI Using original photo sensor and frame.. just curious and you would know or done it .. thank you ..
I have gotten away with that in a pinch. The problem I ran into was the balance being off after the fact. But depending on the unit it might not be an issue.
Hi Frank! on my nec v260 projector a horizontal dark bar appears on the screen at the top ... can you tell me what the problem might be?
Hello Lisandro, I would like to see a picture of the bar if possible but I think you may have a light tunnel that has collapsed or moved out of position. The light tunnel is the square mirror assembly right after the color wheel.
Thanks, Frank! yesterday I disarmed the projector following your very instructive videos and saw the color wheel, before I did not dare to take it out. This afternoon I will do it and I think your suggestion is correct, it looks like a frame out of place! I'll let you know if I managed to fix it. Thanks for your courtesy!
@@FixitFrank Here again, Frank! I completely disarm the projector and rearm it (miraculously)! It works, something really unusual. The bar is still there and I can send you a photo if you indicate an address. Anyway, I would settle for working with that bar there.
@@LisandroLopezBaylon Hi Lisandro, I see what you mean. That looks like it is not a light tunnel problem. The video is missing in the black bar(solid in color). That would suggest a bad DLP chip or a bad connection between the mainboard and DLP board. I would re-seat all the boards to make sure they have connection. If the issue persists, I think it needs a new DLP chip or controller.
FixitFrank Thanks for your quick response, Frank! I can not advance in the DLP, although I have experienced in electronics exceeds my knowledge. Anyway, I can use it when I need high definition in my work and I buy an alternative one (abox) with less definition but with other advantages, like using the USB flash drive. Thank you again for your help !!!
Hello Frank, I have a JVC DLA X30 Projector. I took it to a tech shop and they told me that the color wheel needed replacement. Can you point me in the direction where I can purchase the replacement? Would really appreciate it.
thanks
You can easily replace it.
I'm getting a bad color wheel symptom on my WD73640(Mitsubishi).
The color wheel is supposed to be new. It spins then turns off, spins again then turns off.
Could something else be causing a new color wheel to shut off?
Thanks in advance..
Is it doing that two or three times before stopping? The color wheel sensor would be suspect. Also the cable for the color wheel might be reversed. I am not super familiar with that TV chassis. It's been about 6years since I've been in one of those so bear with me.
I'd check the cable direction (try inverting it) unless you're 100% sure it's right. Otherwise clean the color wheel sensor(small pcb with a photocell) pointing at the wheel hub. Usually has three wires sometimes four. See if that helps at all. Otherwise it's hard to say. Power supplies are known for bad caps. Look up green light of death for that model.
hi fixitfrank i have a samung dlp if i leave somthing on pause it leaves a shaddow the trun the tv of and back on its ok till i do it again any help would be great thank you
Hello Louis, What is the model of your TV ? There are many known issues for Samsung but they are model number related.
@@FixitFrank sp46l5h thank you
Hi Louis, I checked into this and it may be a due to dust, but I would think the shadow would be constant. Since the shadow goes away when you turn it off and back on, you may want to try a new lamp. Lamps going bad might be the cause. Make sure you buy a lamp with an osram bulb inside. www.projectorlamps.com/samsung-dlp-tv-lamp_sp46l5hx.html. As an example. If you are in the USA and want a coupon code for that link , let me know. If the lamp is fairly new(Les than 500 hours) it might be something else.
Hi I found the problem mate its a little piece of glass with a red tint on it its got a border around I think it happened buy the light
It won't let me upload any pics of it
Silicone Lubricant
It would be worth a shot. In my experience any lubricant tends to become saturated with dust. Usually these use an oil bronze/brass sleeve bearing. When they are clean they tend to work best. However if you have had good experiences using silicone lubricant, I would be very interested to know what brand it was so I can try it out. I'm always learning so I would be foolish not to try it.
