- This is part two of my DIY projector video an is done more to show ho you can bypass the Lamp on a 3 LCD projector and what type of light source do you need for this type of projector in order to get good results.
There is also a Blender 3D animation at the end of the video. - วิทยาศาสตร์และเทคโนโลยี

Brilliant. And the animation at the end was really good too. Great work.
Thanks for the comment. I do not think in 2022 it is worth modifying old projectors when there are so many low cost LED projectors available at reasonable costs.
Hi electrodacus, I found your instructional video, above, very interesting and informative. I know virtually nothing of electronics and science - so will not be trying this just yet. I would love to learn more though. Thanks very much for a clear and well-made video.
Thanks for the comment and for subscribing. It will not be hard to learn more having access to so much information.
thanks it worked i found the wire to bypass...it picked xbox 360. now i need to build the light source...keep up the great work.
Hello again, I almost finished my Sanyo 3LCD projector. I used 4die Cree power LED MC-E 6500K. I tried 2700K but colors are too much yellow and there was no clear white.In 6500K it's looks very good, brigthness is enough to watch in evenings and perfect in night. Colors are close to normal lamp. I used half-flat lens and it is best solution. Everything is fitted in original lamp chassis.
@electrodacus... I bridged the wires that you told me and it works, pj stays on and works. I tip my hat to you and I say THANK YOU!!!. I will keep you updated on the progress of the project..
thankx for the vid, great job!
Thank you for that, sorry for the late reply, have had a little trouble accessing the internet recently. I will now have a look for those.
very nice video , thank you.
Hi Electrodacus, just like to thank you for all your help so far, I've used lots of advice you have given in the previous comments to get most of the parts for this build but there is one part I can't seem to find. Could you tell me where you got the mount for the large lens, I can't seem to find one on dealextreme where you said to get the lens from. Thank you
Hello electrodacus!
This is the best modding I have ever seen with a led -especially with that low wattage.
Magnificant! The condenser lens inside the origin lamphouse is simpel but genial!
Are you going to do the same thing with a led light with more wattage?
I would enjoy that!
Thank you for the clips!
MrLecvip!!!
hello electrodacus, thanks for your awesome video as i was able to "fool " a toshiba tdp-s20 projector and now just waiting for the led light source and the lenses you mentioned in your vids.. i have ordered this led -XMLAWT 1000-Lumen LED Emitter White Light Bulb (3.0~3.5V) from DX and a power source (700mA 3W LED Constant Current Source Power Supply Driver (90~265V)
Yeah, that is what I thought would be the case. Those big 10,000 and now even 20,000 lumen LED's aren't single point light sources, the chip has an array. When these are focused on a wall what you see it a magnification of the surface of the chip.The only other way I could think to do it would be to use a diffuser, and then collect and focus that light.
The reason I am interested in this, is at my place of work we supply lots of LCD projectors to bars and clubs
Maybe someday I'll send you photo how it looks. One and only thing to do is to connect transoptor mainboard to turn on and off the LED automatically. Many thanks for an inspiration and knowledge. Evolve yourself. The best wishes for you.
I see, thanks for the heads up.I will look at all that, if that's the case I guess a little noise is not such a big problem
Thanks for the reply. I have a Hitachi CP-X265 3-LCD which is XGA. I like the results you have achieved. Do these type of projectors have a condenser lens in front of the original lamps? I guess I'm wondering how the original lamp light is being focused.
Thanks man, it works :-)
hi, first of all thanks for all your effort and patience, it's guys like you that keep the dream alive for us. I have a proxima dp4100 dlp projector that I would like to use led as light source. I see 5 wires coming from the board green red orange black white but on the other side of connector going to lamp psu orange changes to clear. Are any of these bridgeable to bypass lamp detection etc? your help will be greatly appreciated. Thanks.
I used idea with lens, 200% of improvement. Yes I have multi-die 30W LED, I will try to do test on 5W 3x3mm single-die which I bought few months ago for modification of torch.
Hi Electrodacus,, First off THANKS for all your work with the projector mod's!! You are the Best!! Could you please list the exact Make and Model LED part numbers on your various mod's so the rest of us can take advantage of your work. I am thinking of using either a 50 or a 100 watt 6000 K LED module but am concerned that the originating point of light will still be to wide to achieve any real brightness. PT 1
thank u its work. :)
Thanks ,,,, nice to know ,,,, I was concerned with the overheating factor and the flood vrs the spot aspect, What do you think is the best make and model LED to use for Modding??
Are most fan in the projector just regular Pc Fan? Can we upgrade them to a stronger fan with a lower Noise Level?
Also i need to figure me out abaut the lenses that you put in the front of the led; why did you do that? to obtain equal light on the first lens of the projector? thanks in advance!
@electrodacus (thanks for the lens info, found both) Well, I do have an AC adapter from an IMB laptop that I stepped on and broke the tip off...Could I use this to power the CREE XML? What resistor combination would I need to use for stepping it down?
What about replacing the normal lamp with a photography studio flash - in order to project an image very bright (for a millisecond or so) ... would the LCD screens be able to deal with so much light - would the image still have the right contrast etc?
Nice mod!!!
I am trying the same thing at the moment, found the 3 pin wire that goes to the electronics responsible for controlling the light. Just need to do a bit of testing to figure out witch one is the control and what does the other one do. And see if the projector will display images before I buy all the hardware.
I can get the light source as close as a couple of centimeters from the film. The actual film area on 35mm is about 2.5cm square so it's not tiny. I don't have any optics in the light path yet, I'm still researching how I can do it really. The back of the projector is totally open with the shutter then the totally exposed film. From there it goes through the backup lens and then the anamorphic (if required).
The best LED you can use in a converted projector is the CREE XM-L.
Unfortunately this is a 10W LED and puts out around 1000lumen maybe less depending on bin so about 50 to 60lumens out of the projector.
But this is the largest you can use it has a 2x2mm die and that is about the limit so that you can collimate the light in to a laser like beam.
Because LCD or DLP is smaller than 3cm diagonal and distance from light source is about 30cm the spot from 1m needs to be less than 10x10cm.
5000-6000K.
@electrodacus Yeah the central one is ground, connected to 2 optoisolator, but they are in opposite direction. Just connected the central one to one of the other 2 on either side and both time the "Light problem" led light up.
Wonder if there is another way to trick it into thinking there is a working bulb, big resistor between the contacts that go to the bulb...?
Will do a bit more testing if I have time this weekend, I would love to have a project but cant afford a new one.
I tank you very much
@electrodacus
Thanks a lot for a very nice mod on projector. I have currently a panasonic projector with a busted bulb and would like to know which CREE XM-L Led I can use. There are 3 kinds of it. Can I use the cpu heatsink for it? I can easily modify the circuit to fool the projector into thinking that the bulb is working. I also have access to lens in order to focus the light ( lens with almost 3.5 inches aperture and is apochromatic or color free).
Thanks again,
pokoy
Its a good video thanks. I'm looking to produce a prototype square spotlight with variable focus from a small 60mm10w phillips Fortimo Led (DLM 1100) and thought the use of a condenser lens would be effective. I was wondering if you know if this would work?
hi electro,
the lenses i bought off dx were those of what you specified and was able to focus it , but it's really dim even in the dark.( the led seemed to be bright as i can't stare at it directly) although it might still give off more light if the right driv er is to be used. so may i ask for your power source design like the one you used in this video(old laptop power source and the resistors' size and value to step down the voltage)...thank you in advance and more power!
Hi Dacian, by any chance is there any newer one die led more suitable than the xmt60 I got from DX when I modded my Projector? I remember you telling me back then that there were not other better emmiters for diy modding ate the time. thanks for your kind help. MArcelus
@electrodacus...thanks for the speedy response. I will send you some pics as soon as I can.
Very good modification, can you tell me what diameter are the glasses? or how many degrees are?
Thank you very much !!
I want to replace the xenon arc lamp in a 35mm movie projector with an led for home use, I have seen these 100w LEDs that seem like they would be useful for this but I imagine I'd need some precise mirrors/optics to pull this off? I'm building a lamp box from scratch.
hi again electro, so what would be the equivalent of making a single power source to sum up 4 of those drivers?(watts/voltage/amperes) cheers!
Thanks. Where did you obtain the lenses for your led?
Would a 10W Cree give enough light to see very much though? Film is likely denser than LCDs so would probably require more light. I suppose for £10 delivered it's worth a go though.
cool
Thanks for your attention :)
These days, when arrive 1800 lumen LED flashlight, LED will pull out and do experiments with him. I have some lenses and I'll try to put it as close to the color wheel on my DLP projector :)
But I not giving up and diode 100 watts! With ordinary lenses is impossible to focus, now try 2-3 daysI
Now my last hope is to focus all his light with the help of Fresnel lenses. I guess a month to arrive and fresnel lenses for last experience with 100 watts diode.
When you see it is projected on the wall, put in a room with a lamp or daylight? Do you have pictures posted somewhere how to see?
the laptop adapter did you connect it to projector power connection. does led power on with projector or is it separate from projector..thanks
The ones i have ordered are 150w Osram powerstars ($2.50 each), small enough to fit in the original lamps reflector. So that solves one problem, also they last 8000 hours and as for the LCD's i have a spare projector the same model in pieces with good LCD's in. Im hoping they will work with the UHP ballast, Metal halides are also HID but they are AC instead of DC. If not i will have to buy a ballast i guess ($20)
@electrodacus not sure which one..should i just ground each one until i get it to bypass...will i short something if i do this?
Ok, ballast is already out, I am also considering replacing the noisy fans with quieter ones and more directed airflow. I also think that my led and heatsink assembly will fit perfectly into the old bulb bracket. Should make for better light direction too.
Hello electrodacu, thanks, much appreciate it,however, I had already tried the 50mmv x18mm lens on its own, but with the 45mm lens I got better results, but the image is very dim rather than unfocused, I will try using the 22mm lens in between the LED and the 45mm lens, but I do know how you managed to fix the 22mm to the LED and find the correct focal length.I thought I can push the LED current bit higher,for brighter light. is that OK?
Today I just got new XMLAWT SKU 51989 from DX.for DLP proj
i was really wondering if this would be sufficient for the led.could you advise me if this power source is ok or might give me some tips for a better power source( a diagram maybe and the values of the components) thanks and more power!!!!!
since the multiple little LED's on the panel act more like a flood light pattern than a tight spot pattern. It seems like the Cre Xml series had a much tighter point of light but I am concerned that it might not handle the wattage. I am also considering using three separate LED's directly behind the LCD polarizors and panels as well. Pt 2
This tutorial is amazing thank you so much can you explain why the forth photo you took of the projected image is much dimmer than the first three photos
On the first photos there was much more white in the image and probably camera settings was different. 25lumen is not much and similar to what you can find now in LED projectors build in a smartphone.
how important is it to use a lens on the led. I am using a 50w prime led rated at 4000lm that i had for another project but my video is still quite dark. Any suggestions, and can u recommend a lens?
ОК Thank you :) However, I will wait a few weeks to get 5 fresnel lenses and try them and with what. I'll write about the results.
Now came 1800LM cree xml T6 LED and try, and with it + 5* collimator.
Metal halide works with stock UHP ballast, and is bright enough to make a big room go bright white during the day with windows open. testing right now to see if it projects an image
What is the lens used in front of the LED. EBay Item? Would I be able to use a 12V power supply from an old PC to power the CREE XM-L LED? I've bypassed the ballast board on my Sanyo PLC XU31, and put a car HID bulb in with the 12V power supply, but its not bright enough and the beam is not focused. This LED/Lens combo looks like its solid.
It's a movie projector (like you would see in a cinema) though it's not all that big, most of the bulk in those is in the base and the lamphouse. The original lamp would have been a 500-1000w xenon arc lamp. Just a large arc lamp with a big reflector behind it. No optics for light convergence or anything like that. No idea what the lumens would have been originally, a lot I recon. But that would have been for a 200"+ screen!
Is generally well focused 1800lumena diode cree will achieve better results from xenon bulb!! Can be seen in the room with a lamp or barely visible picture?
Hi Electrodacus , Please show how your lens assembly is made a, what lenses are you using?
Good
you have by far the best explanation! Can you please tell me what lenses you used to focus the light?
I do not remember the size of the lense but they where aspheric condenser lenses.
Ok i got it bypassed, whats the least expensive lighting system to use that works pretty well ?
Speaking of the 100w LEDs, wouldn't it still be brighter even with a loss of light than the 10w Cree?
hello once again electro,, ive managed to test the led in the projector with the ordered power souce from dx (just one driver) although the led is amazingly bright, but yeah, it's not strong enough to let the light through the projector's focus lense....can you please help me to find the 3amp driver or better yet help me to build one so my dream of having one like yours would be successful.... more power elctrodacus!!!
and these often come back to us with the bulb blown. We end up throwing the projector away, because the value of the projector by that point has gone down so much. I was looking for a way to replace the bulb with an LED that would be capable of outputting a comparable number of lumens.
Hello all :)
I apologize for my bad English.
I have one year to 35w Xenon modified DLP projector. The dark look good in daylight barely visible in the evening of the lamp is visible picture, but funds for watching. The xenon bulb is focused on the original reflector spotlight, with many attempts I did adjust optimally.
@electrodacus
i found the control wire, and I can make my machine run continuously, but I have trouble focusing the light of the projector lamps. Tomorrow I will buy the headlight of flashlight C30 and use, i hope complete
very nice speak ;D
@electrodacus Pictures of 13-16 were made by Osram cool blue H1 powered 13.10v.
I'll announces a diode with a very small area of the matrix - cree xml led, perhaps.
I'll think more these days, these diodes want special power, but the lens and the LED will require a special stand. I do not know if there will be enough space for diodes, lenses and radiator cooling.
Hi electrodacus
I have a different model of Toshiba projector: Toshiba TDP-SP1
Currently I am trying to figure out if the power supply can be fooled or not.
It has a cable with 5 wires connected to the main board:
- two of the wires are +5V and ground
- the other 3 I presume are connected to the 3 optoisolators.
Please advise if it can be fooled somehow.
Thanks!
👍
o ok. ya i was just trying to bypass it cuz the ballast is no good. but thank u.
Hello there, i need some help, i just moded my sharp that has 2 optocuplors, and now i don t figure abaut the led to put inside it. What kind of led should i use? i need bright image, my room is a bit lighted, what colour temperature is better to use, and also i see on the market 50w leds (the most powerful on this market), but it surface is flat, not bulbed like in this video.
What about a 20w LED that puts out 2000 lumens ? Im quite new to this circuit stuff so i was wondering is there anything like a solenoid that i could jump off a fans power supply to turn the solenoid on/off, then have the solenoid as a switch on the LED's Neutral or Positive input ? So when the fans turn off the LED turns off too.
@electrodacus
I have built some DIY projectors, and also succesdul modded a commercial projector some years ago with a H7 car bulb :). I love modding and have tried the led-light as well -but only as a 3w powerled -and it was not so succesful as your modding.
I thought the origin fans for UHP-lamp was enough for cooling a higher wattage led light..
If you find a solution to cool the high wattage led light you should have the official Nobel Price of modding :)
in the future!!!!
Hi man,can I make this same also with a new projector,or couple years old ..? Example BENQ MS 513..?
Buna Electrodacus.I have a Toshiba HD TDP-T100.Unfortunately it was without the original lamp. I want to build a LED lamp.I read you comments about the high output LED(PRIME 50-100W).You are saying that the light cannot be focused in a small area. What about this product: sku 43044?My idea is to use a 100W LED(SKU 42806), with reflector(SKU 39974) collimator lens(SKU 43044),power source(SKU 47306). What do you think?
how do you make the bulb ? or led lamp i got a similarXGA327 and want to hack the same thing on my projector i've followed the tutorial and done exatcly as you have done except the 2 orange wires are'nt there are they a different color on my one and how do i make the led light ?
Would a high-power LED flashlight drop-in module work?
@electrodacus
i have projector dlp, if mod light bulb, can i use cree xm-l or sst-90?
When i remove light bulb (orginal), the projector only run 50s and auto off. i don't undertand!
i'm vietnames
Hello electrodacus, super excellent, been following you videos and posting on lumenlab.com, and decided to give it a go.The only problem I have is to focus the LED into the LCD. It seemed there is light everywhere but not inside the 3LCDs chamber. I got a bit faint and unfocused image from using SCC P7 with 3.6v. 2.8A, into a 45mm lens (4-80 deg angle) in a Panasonic AE100 proj
I would very much appreciate it, if you tell me what Lenses you are using (Dia sizes, angles and focal lengths) Please
This is a great video. Many thanks. For a 120W bulb, do I need a 120W LED or there is a rough way to calculate how much watt LED will replace 120 W normal bulb ?
+hypertuch To get the same amount of light you will need roughly the same LED power but you can not converge light using a lens form an LED die larger than about 2x2mm and the most powerful LED with such a small light surface is around 10W.
The commercial available LED projectors have LED's for each color and much closer to the LCD or DLP.
Unless this is just a hobby is better to get a proper LED projector than to play with modifying an old projector. I made this video more than 5 years ago back then there where no commercial LED projectors available.
I got about 25 lumen from a 6W LED so you can expect at most around 50lumen output form a modified projector with a 10W LED.
many thanks for advice. Indeed you are right. The problem is having a good quality projector with old bulb. the bulb at silly high fixed price. price fixing is just like many other things. so i probably hear ur advice, and try to work a solution.
Hi i need help.i have a sanyo pro xtra multiverse projector which im trying to convert to led power. i have managed to bypass bulb ok circuit but now the projector goes into shut down after about 25 seconds. tha manual says that its because of unuasual high temperature or cooling the buld befor shutdown . there are 5 wires in the bypass plug so would you have any clue as to what i would need to do to keep it running.
Hopfully
Dominic
. Do you have any idea how to test the optocupler sending so that i can find out the signal that it is sending and mimic this signal with a microprocessor? also if you know how i can send you a picture of my lamp assembly just let me know. The led is a SMD that is running on 19volts and is mounted inside the existing bulb housing on a heat sink, and it has a condenser lens on it.
How do u stop the protection light from coming on i have a epson h311a projector
Hi again,I find service manual to my hitachi projector.What wires connected together..?1.lamp pwm 2.GND 3.lamp miss. thanks for answer
Need your help. I found the optocuplers. and the pin out wires. theres is 5 wires. not sure which one is for the lamp signal. what do you do with the wire when you find it?...i posted a quick video of my attempt..let me know please...really want to do this mod.
Guys, what bulbs are you using?
I use Osram cool blue h1 and a modified 13v pc power supply.
The dark look very good looking and in slightly lit room.
Tried and hid xenon but the effect is like that with halogen osram, except that money is more about hid.
A modification of the video work flawlessly :))
How many LUMENS did you get for Watts IE 100W LED = 4000 Lumens
Something like that
What wattage did you use? Would you use larger or smaller or same wattage?
Is the LCD a HOT or a Warm white LCD? Wave length used? That is if you still have the information.
If you purchased the LED on EBAY... Do you still have a link to the item or seller or like item?
Thanks you saved me and I am sure many others throwing out projectors needing new out of stock bulbs.
i cant seem to send you a picture of it but the projector is taken apart and i have the HV power supply out and i have foung the controlling board for the lamp, it has 3 optocuplers on it one on the top the is recieving, one in the middle that is sending, and one on the bottom that is recieving.
I have on order this LED "PRIME 20W 2000-Lumen LED Emitter Metal Plate - White (16~18V)" plus power supply and heat sink. do you think they will be ok?
Well ive tried unplugging the switch, shorting every way possible, grounding them and its just a Ballast error, if i put a halogen in the ballast it works.. but its not very bright and its just a matter of time until the halogen pops.
Doesn't work, i tried it. I think it has a serial communication and it defiantly has octocuplers. Will a Metal Halide of the same wattage work with the UHP ballast ?
how can i buy pass the existing bulb in my Epson EX71 with a 30watt led, i just need to know what i need to do to trick the projector into thinking the bulb is still working?
Hi bro your video is very useful to me please tell me that what differents R G B lcd chips in lcd projector
Sorry I do not understand the question. Modern commercial single DLP or LcOS projectors use 3 separate Led's R,G and B that are controlled in sequence so you will have that flicker and rainbow effect. This is a 3 LCD projector so an LCD for each color and white light for a lamp is split in to the 3 colors to supply to each of the 3 LCD then image combined with a prism.
Is also possible to have individual RGB Led's one for each of the 3 LCD but that is not very popular as is more expensive than single DLP or single LcOS (also an LCD but reflective).
Hi i have a Hitachi ED-X3270 and i need to bypass the ballast, on the wiring schematic the wires going to the ballast are 1: Power-On/Off, 2: GND, 3: Lamp Miss & 4: Selct .... how do i bypass it ? Thanks for any help
Good job, I like it. Many thanks for the inspiration. I have 30W Power LED + reflector as collimator already installed in my Sanyo PLC-SU35 - 3LCD. Brightness in dark room was not exactly like I expected. And here is my "brightness" :) Lens is the key to success. Tomorow I'll be back with results. I've found beautiful lens ø=60mm. I hope, that it will give 200% of improve.
Can you use led luminus SST-90, it's 2200lumen, 3V 9A. I hope it will carefull
Hello There man nice video i had NEC NP410 projector i need to know how to hack his lamp i am also planing to install the LED whait for your reply Thanks ..
is there a way i can email you directly with photos and serial number. Also i i have not seen anything which looks like a sensor on th bulb enclosure.
P.s thank you for a fast reply.
I just opened my VP and run into problems.I discovered the switch lamp cover.I closed the circuit.Then i uncoupled what i think is the lamp elec.source( voltage? can i use a hid bulb?).The VP starts, rotates the color disc for 1 min,and for 10 seconds i can see the projection of my desktop(using a cree 3W flaslight) after this it enters a sleep mode with the fans on. it shuts down after 2-3 min.
