Nice job Frank 👍 This is my bedroom projector, 8 years and still going strong ( 2 bulbs changes in that time ) had no problems at all. But if my colour wheel needs changing I've got it with your help once again. If any of your subscribers are looking for a good cheap secondhand projector you really can't go wrong with this 141x, great crisp image 👌 Top man top channel 👍
Hi Frank, just wanted to thank you. I live quite remote, and having to wait weeks on two bulb replacements thinking that that was the issue, was pretty frustrating. Who would know, a piece of electircal tape saved it from the bin. Great Job and thanks again.
Mine still going strong after your last video on these. Your advice was absolutely spot on and I changed the bulb ( making sure I got the one with the shimmer ) and the colour wheel.. definitely someone will find this helpful
Hello Frank, I have some problems with my Optoma uhd51alv, I guess you are based in Usa? So it doesn’t really make sense to ask u if I can sent you from Germany … But maybe u can help me abit , it was super dirty cleaned it completely and now, the blue lamp is turning on if I switch it on and that’s it nothing starts no fan no light nothing, if I open the chassis of the lamp and don’t press the (closed contact) it’s turning red and lamp light is flashing …, if understood one of your videos right this might be the the color wheel sensor (it was very dirty too like burned in dust). Greetings from Germany
Hi Frank, just found your videos and had a question. I’ve had my HD141x for 7 years and the Original bulb just exploded. I bought 2 different bulb replacements and they never turn on. I am getting voltage reading from the lamp connector of 84VDC and 94VAC…not sure if the output is AC or DC for these lamps? Or if that is even correct. I read that it could be a ballast issue. Just looking for more insight before I buy a $100 power board.
Unfortunately you can't really measure the ballast output correctly or safely. They can output 3-8kv during startup when it strikes the arc. Then it balances the voltage and amperage to keep the arc going. It's also running at 20khz instead of normal AC or DC. You can damage your meter really easily if you catch an ignition pulse. The best way to test your ballast is to check the power to the ballast. The pfc input to the ballast should be 380vdc. If it's 160-300 that means your main power supply has a problem or the main board is not calling the pfc to enable. If you have the 380 then you need to check the control lines. Usually pins 4-5 are the lamp on and lamp power level pins. You should see them start at 4.8 ish and then drop to 2.5ish when the projector tells the ballast to turn on. If you see both of those, and no lamp ignition, then you probably have a bad ballast. See what you find there and let me know.
I am in the same boat. Same age and projector and my original bulb just exploded. I watched a couple of his videos and he speaks about not buying bulbs on Amazon because they cause other parts in your projector to fail. If you got one from there, you may want to return it and check out where he gets his bulbs. I just ordered one as everything just happened today for me.
@@willardmoore7685 yea I ended up fixing the projector with a new transistor, and a new bulb. The Amazon bulb I got is working, but it’s definitely not as bright as the original
Hello Frank!!! The color wheel of my 7 year old optoma HD141X shattered a few weeks ago. I ordered a new one and after it arrived I began to assemble everything but the plastic support of the color wheel was missing because it was placed in the trash by accident. Is there a place where I can buy a replacement or maybe a place where I can find the 3d drawing of the part so I can 3d print it.
3d printing is going to be tough. I dont know of any filament that will hold up to the heat. I would email my friends at Time Electronics in China. They work with e-recyclers and may be able to find you one. Their email is gydz@timeprojectorlamp.com I think they would be your best bet.
How do I know if a noisy projector is a fan problem or a color wheel problem?? The image is fine but the noise gives me a terrible headache. (I have an optoma hd 141x) Thank you for the helpful videos!
The nice thing is that the color wheel only spins up when the lamp is working. The fans will run after the lamp turns off. Turn on the projector. Once you hear the noise, turn it off. Once the lamp goes out, the noise will stop if its the color wheel. If the noise continues until the fans stop, its a fan. If you still have the original wheel, its probably the issue. You could also post a short video on your channel and let me know. I can tell by the sound most of the time.
Thank you@@FixitFrank!! Here is a video of the noise: ua-cam.com/video/ctGRJI1OSIM/v-deo.htmlsi=UCOs_oMxvtH9sbDr My phone mic doesn't do it justice but it's a constant buzzing. I verified the black tape is still intact and at the right location, it seems to spin well enough, the color wheel sensor and housing was dirty but I cleaned that as well as the color wheel itself. The grey pad showed no signs of damage or adhesive failure. What do you think I need? I am also due for a new bulb if you could recommend a place to buy one!
I must admit, I don't hear anything obvious in the video. If the buzz happens after you tell the projector to turn off(while cooling down) then it is a fan. If it only buzzes when the projector is on, then its a color wheel. As far as new lamp, I would suggest anyone on this list. www.projectorcentral.com/projector-lamp.htm I prefer purelandsupply but I am biased. They are more expensive than some but their quality and service are great. Just stay far away from amazon. For power banks and stuff, amazon is fine but for lamps, they are just too much of a gamble.
Hi Frank - just wanted to say your HD142X disassembly video was great, am working on sorting mine out at the moment. It makes a very loud buzzing noise which I initially thought was the fan but after taking apart and cleaning, it seems like it’s coming from the colour wheel. Is it likely that a colour wheel replacement would fix this, or is there something else I should try first? Am wary about swapping the colour wheel especially without a video for this specific model.
Im in Pennsylvania. If you want to send in the projector, I have to ask you to do some footwork as I can't technically advertise at the moment. If you click the lamp link that video and contact the support@ email on that website that it goes to, then I can help. Im sorry to be all cryptic but I get inundated with repair requests and since this isnt my full time gig yet, I have to make it a little difficult to find me. Also if you post on the ProjectorCentral user group on Facebook, I can be found.
Hi I have a h180x Optima which turns on wheel spins then stops and fans come on. This repeats a few times with a blue flashing light but then the light just flashes red. Color wheel has the black market and sensor has been cleaned would this be the bulb?
Great video, the whitish section of my wheel seems to have detached itself from the wheel.. is it repairable or do I need to change it? I can't seem to find the original part in Canada. Any advice? Where are you located? Can I send you the projector for repair? 😅
Im in the states unfortunately. However I can tell you that most color wheels on ebay will work fine. There is no original color wheel anymore. In fact even the originals were just inexpensive color wheels. If it says it will fit, then you are in good shape. If you want, email the folks I use in China. they can help. Gydz@timeprojectorlamp.com you dont want to try and reattach that segment, the balance will be our and most likely the other segments are not far behind. Color wheels are pretty common parts to replace. Once you change it, your projector should be good as new.
You can use black kapton tape. The trick is to use something that can stand up to the heat and is a matte or not too shiny black. Stove paint is a good option, or matt engine paint. I'll find out what this tape specifically it though. This was actually given to me by another tech so I dont know where to buy it. The piece I have will likely last years.
Im fighting a gt1080 with this. Once I figure it out, I will post a video. You may want to try another wheel. I am starting to lean that way myself. I have one on order but its not here yet.
I will. It'll either be a long "short" or a full video. If a second wheel didnt work for you, then I will start looking at other things in the meantime since I wasnt sure if the second wheel will help.
Hi, While replacing my color wheel i seem to have broken the clip for the ribbon cable any idea how i would go about finding a replacement part or fixing it myself. I have no idea where the bit of plastic has gone so would either need a repair with a new one i could buy or alternate items. Any help would be great thank you.
Ohhh. That is going to be difficult. That is all one unit so you can't buy just the clip. The only way to repair it is to replace the entire connector. you might want to try creating something to hold the wire in place. Maybe some kapton tape and a piece of plastic to push on the wire so it makes good connection or something like that. I'd really search for that piece. Even if its broken, you can put it in place and tape it down so it'll work. But replacing just that part isn't really an option.
Hi Frank. I'm wondering if you could help me I have an optome 143X and the picture went out, the bulb was still on and after watching your videos I took it apart and found a little burn on the color Wheel chip and ordered and replaced both the color wheel and the chip that sits on top of it. When I replaced it it started working and I was happy. but then it ran for about half an hour before the same thing happened. The lamp was on but there was no picture. Just a mix of black and grey. 1. Any tips on what is happening? 2. Do you accept any repair orders? I live on the Big Island of Hawaii so I am pretty sure there is no one here. Maybe Oahu? But I trust your work! Mahalo!
I'm on the other side of the USA (south east PA). I'm sorry that I don't know anyone else who works on projectors in the USA. It seems to be a very niche repair industry. That said, have you replaced the lamp? If you saw burning on the color wheel and CW sensor, its possible the lamp has an issue. If the lamp was replaced with a non-original (or one without the proper red/blue lens filter) it can cause the Infrared radiation to cook the color wheel and drastically shorten the lamp life. Cheap lamps end up being very expensive. If the projector is still trying to come on, and you hear fans and see the color wheel spinning up, then I would try a lamp that has the proper UV/IR cut lens. www.projectorcentral.com/projector-lamp.htm Anyone on here is safe to purchase from.
@@FixitFrank thanks Frank for your reply. It's the original lamp. I'm sure it has been used a bit... if it is the original lamp, wouldn't it just go out? Or could it have another problem that would cause to picture to stop projecting even tho light is being emitted? Sorry to bother. Not sure I want to invest $100 in a lamp when there is a deeper issue, so trying to eliminate possibilities in my head 🤯😵
@@FixitFrank btw the original color wheel spun fine. There was just a little black sooty material on the surface of the sensor chip. I replaced both just to be sure and it seems that color wheel seems to fail anyway. And as I said, it worked fine for a half hour and failed again.
I'd still try another lamp. If the old lamp is weak, it can cause issues. 90% of problems end up being lamp related. I understand the hesitance to replace the lamp. I would suggest buying one from a place that takes returns. then you can at least get your money back in the event that its something electronic related on the mainboard(only other possibility)
Hey Frank, I followed this and discovered the tape was essentially gone on the color wheel. I put some isotope tape down and finally got my rich red colors back instead of the blotchy orange hue. Unfortunately after an hour the color reverted back to the orange blotchiness for the red. Do you have any suggestions?
I would replace the color wheel entirely. If the sticker came off, it may mean the wheel got too hot and the oil bronze bushing is no longer working and the wheel is dragging. It may also be that the tape melted off. That area gets very hot. you need to use something that will handle 150-300c to be safe. I have used stove paint, high temp black tape with good results.
Hey! What can be wrong if the color wheel looks good and seems to be able to spin without any problems, but doesn't spin when I try it on? It moves smoothly when i touch it...
I think there is a screw hidden in the center of the knob. You need to peal up the little plastic sticker that covers the screw. The knob looks like one piece but I am pretty sure the center part is a sticker.
@@FixitFrank thanks for the great videos you are making . i wonder if you have any suggestions about my benq w1500 , it was always plugged in a power outlet , the orange/lamp was on ( stand by mode ) until recently it wont power on ( no stand by light at all ) i took it apart do see if i can see any physical damage on the power bored such as bad caps but no results , can it be a bad lamp , have never changed the lamp sens i bought it new in the store many year ago .

Hey Frank, i recently replaced my color wheel and bulb and when i turned it on the test grid is not uniform. The bottom of the test grid is faded black. How do i go about fixing this? Thanks!
I changed the color wheel on mine but now the right and lower side of the screen are dark. As if something is blocking the light going through or going out... Any ideas

Fantastic job again Frank...to make the super glue even stronger sprinkle some baking soda on the joints..
