Where did you buy the bulb and how much was it? Because on viewsonic website is $235.buying off market generic brands are they any good. I'm thinking about buying PX748.
Just FYI guys you dont need a pro to replace it, the crimped metal the wires are attached to just pulls off, and you can then push it onto the new bulb, very easy
I don't have a specific video. I blow it out with compressed air or air duster. Compreased air can be humid so I allow an hour before turning the projector on. I use a chip brush on hard spots. Try not to blow dust further into the case. A person might be able to gently clean the color wheel with a Qtip. Never spin up the fans with the air (for fun*) because they will act as motor generators and back feed electrical current to the board potentially damaging components. I always hold the fans still one way or the other.
Great video. Turns out my problem though is the color wheel itself. Do you know how I can replace that? Or even order a replacement color wheel? Or is my PX747-4K projector toast? THANKS!!
I had the color wheel problem and bought from ViewSonic for $150. You have to take all the boards apart (it sits on bottom front upside down) and mine hasn't worked since. It may be broken in another way or I need a button code to reset the projector. If you know you know, and if you don't, ❤️🩹
I am thinking about buying viewsonic PX748 4000 Lumens, but i checked the lamp price on viewsonic website for $235. is the generic lamps any good? thanks
The generic lamps work but it is better to have the OEM lamp. Some of the more expensive options include the cage which you don't need unless your time is very valuable monetarily. A new lamp of any make is better than an old lamp of any make.
@@jeet-Seattle Those Lazers go out too I heard from a tech it's like 5 bulbs or so and then $500 to replace. I like the LED idea but it would have to be like the ones that last. ViewSonic does have an LED projector that looks like A JVC or Sony but it doesn't seem as popular. 240hz is nice and even at 1080P, I play Dirt 4 (need 4090) and the information comes across in buckets and looks lifelike on my UHD38X which is same generation as px748.
@geostomp thank you very much brother for replying and helping..LED come with 20.000/30.000 hrs but they are expensive, but you know better ..so I think I will just get that PX748 4000 lumens bright..
I also have a few generic bulbs on hand www.ebay.com/itm/165778452068?mkcid=1&mkrid=711-53200-19255-0&siteid=0&campid=5338683291&customid=Px747Bulb&toolid=10001&mkevt=1
Hey there, great video. Do you have a link for the bulb? I just got this projector in February and it already gave out on me. I don't think i have 400 hours on it yet.

The 747 is billed as a daytime projector, and I used a paint formulation to achieve high gain reflective properties as seen in my wall painting video ruclips.net/video/MUdvgIKlllg/видео.html.

My viewsonic was at almost 8000 hours and I finally changed the bulb myself with a Philips and it is indeed much brighter than before.

@@TejsWorld thanks
Thanks for your help sir! For those watching, this is exactly the same steps for replacing the bulb in the PX727-4k as well
Thanks for the vid. Very informative, straight forward, and really helped me get my projector bulb replaced. It looks so much better now.
thank you - much appreciated. have just had a bulb blow but have the replacement. fingers crossed.
Thank you for the video. It worked! I think I blew mine out and I replaced it exactly like you had shown.
Now we all need battery backup so when the power goes out, we can shut the projector down property. A small UPS (uninterrupted power supply) would do.
Thanks for the video
but..... what about the end of the replacement process
That was when I called my local TV repair man to finish the job.

“And these clips on bulb should come right off by pulling”. Dang! Broke it. Bought the new housing and finished the video 😂

Do you have a video on how to clean it mines all dusty and turning yellow

Wait,what ? U didn’t show how to replace the bulb ? U waisted time on cleaning……
Do you know how to reset the lamp hours?
It is in the Installation Menu under Light Source Settings

I haven't done the color wheel on this model. Replacement will be common in a few years, but most are only getting to their second bulb.
@@geostomp I've searched and searched online but can't even FIND a replacement color wheel part :(

The link is in the description
I have one it shows horizontal lines when projected what could be the issue?
Ribbon cable loose
@@geostomp ok
Had mine set to ECO....bulb lasted pretty much 2 years on the dot.
Yeah, best to change it before it pops. It is better for the projector. Also a UPS is smart. Eco is plenty under 100" screen size.
@geostomp UPS? And Eco is actually good up to 130" but you have to have the room totally dark.
@@jerometruitt2731 Uninterrupted Power Supply
@@geostomp I'll look into that
Was the original lamp from the Philips brand as well?
Yes
Too much for cleaning, should focus on replacement and lamp timer reset

The bulb wires clip on and off with a spade style connector.
