Epson Home Cinema 2150 LCD Projector Repair | No Turn On | Mainboard and Power Supply Replacement
Picked up this Epson Home Cinema 2150 from eBay. It was listed as not turning on. Price was reasonable and I have some scraps and figured it was worth looking at. There is always a gamble with the optics of an LCD projector but since this one had no problems when it failed, I didn't expect any. Its always worth considering that though, if you are in the market for used projectors.
**As of this video it is already sold, but If something comes up, I will post it on the community page.**
The issue ended up being the mainboard. The power supply was okay.
If anyone has a clue on how to handle these flat flex connectors, please let me know. I can't find any latches or release or magic spell to open these things. I guess its possible they just have the cable plugged in but I'd like to know for sure if anyone out there knows.

SMART
smart-lightraise-60wi-dlp-short-throw
I was sent two of these Smart SLR60Wi projectors from a school. One had no audio out and the other has a mainboard problem.
The second projector video is/will be linked here.
(It's not, I don't have it uploaded yet, but it will be a little later today)
This projector had some physical damage, either from shipping or whoever looked at it before me. I think the schools tech took a crack at it.
I was able to fix the main problem with some DeOxit G5 (Gold) contact cleaner. This stuff is amazing contact cleaner. I swear by DeOxit brand stuff. It's not cheap but a tiny bit goes a long way.

DeOxit Red (my regular go to) https://smile.amazon.com/Hosa-D5S-6-DeoxIT-Contact-Cleaner/dp/B00006LVEU/ref=sr_1_2
Those are not affiliate links. I might set that up though, does anyone see a problem or is that cheesy to do?
The fan was pretty clogged as well. I take that apart and go over some things. I definitely mention my love of Endust...
I did lose/not get some footage at the end. The plastic top was not repaired for this projector. I decided to use the plastic top from the second projector on this projector. Then I repaired the top and installed it on the other projector. Doing that allowed me to spread out the damage so that both units are in reliable condition rather than one in mediocre at best condition.

TROUB

Sometimes it can be tough to tell if the white specs in your picture indicate a failing DMD or just some annoying yet cleanable dust.
This video gives a quick demonstration as to what a dusty DMD looks like and how to tell.

BENQ
benq-w6000-dlp-projector-repair-cleaning
This BenQ W6000 was sent in with a fan warning/fan lock error. Upon further diagnosis, I found that an old lamp assembly had burst and showered the inside with quartz glass bits. This is a common issue with many projectors. The piece of glass found its way down the air vent into the back of the lamp blower fan. Since these fans are low torque, it jammed the fan.
See the bookmarks below to jump around in the video. I am going to try and add these to all videos in the future and at some point add it to past videos. Feel free to do it yourself and share. I would appreciate any help with that.
In shipping the glass came loose so it saved me a little troubleshooting, but when I initially put the fan back in, I tried to cheat and it bit me later with some vibration noises.

PROJE
projector-lamps-from-amazon-can-ruin
While there are a handful of reliable sellers on Amazon, the large majority are selling products that at the least will not last and at the worst, will damage your projector just like this.
The same goes for aliexpress/Alibaba. Buy your lamps from reputable sellers or risk damaging your projector!
https://www.projectorcentral.com/projector-lamp.htm Anyone on this list should be reliable. Check the reviews, prices, warranty etc and make an informed choice.
Thanks for watching!

BENQ
benq-mh740-dlp-projector-repair-no-hdmi
This is a BenQ MH740 sent in by a viewer who had some trouble after a storm. We suspect they got hit through the HDMI 1 port since the TVS Diode arrays(That I kept calling transformers for some reason) were shorted.
I had to replace the one HDMI switching IC and 2 of the TVS diode arrays.
It's still fascinating to me how many different projectors use the same chassis and layout. I'm sure to more professional types this is not a big deal but it strikes me as interesting. Maybe I'm just weird. :)
Here is a list of all the different projectors that use the same lamp as this model. Most of the internals will match as well. The main-boards, DMDs, and features may vary but fans, power supplies, ballasts, etc will be close enough for the most part.
Some models use lamp housings with a different notch pattern on the front, but those notches can be dealt with. The Philips lamp in this model works across all of the other models.
BenQ Models/Lamps used:

I was able to edit the 2 camera shots a little easier but I still need to update my PC to handle the 2 sources at once. Either way, I hope you find the information you need!

OPTOM
optoma-hd142x-dlp-projector-repair-shuts
This Optoma HD142x (vdhdnl) was sent in via my day job after the owner purchased a new lamp and still had the same results. After some troubleshooting via email, it was determined it was better sent in. It had the color wheel replaced last year but it was only running for a short erratic period and shut down.
I had planned on changing the color wheel but remained skeptical that a 1yr old color wheel had failed. It turned out the color wheel sensor was encased in a weird dark dirt. The whole projector had what looked like smoke residue or exhaust residue everywhere. I have seen lots of types of dust inside of things but this was something unusual. I still don't quite know what it was but I suspect it was smoke of some sort mixed with dust.
There were some other surprises like the speaker cabinet screw in the center and some missing screws. Luckily it was able to be saved and was returned a few days later.
Here is a lamp for this model, use code YT50 for 5% off. https://www.purelandsupply.com/optoma-projector-lamp_hd142x.html

benq-mx710-evaluation-and-diagnosis-part
I picked up a pair of these from fleaBay for a reasonable price. I need one for some lamp testing for my day job. I go through this one to make sure its clean and functional. Unfortunately both ended up having bad DLP chips. The seller was very cool about it and refunded me half the amount I paid. Fortunately I found a good DLP chip (1076-6038B). Part 2 will be up in a day or two once I finish editing.
