Epson 84+ / 85+ LCD Projector Cleaning

- This is how to clean an Epson 84/85+ as well as many others. Any projector that uses the V13H010L50 lamp should follow these steps. One thing to keep in mind is that the projector in the video is used and I suspect was damaged at one point. There should be another screw in the upper left of the mainboard.
Again, I do not recommend opening the optic block as you can cause more damage than can be resolved reasonably. Enter that area at your own risk. Take your time and all should be well. Thanks for watching!
I have an 84+ and currently I have a few "green blobs", on my screen when I watch something. I read that it is dust from the lamp. Is it ok to just take it apart and blow some air on the part or parts that might be causing the "green blobs"?
Hi frank thanks for the video! I did everything but when I tried turning on my projector after I finished cleaning it the fans went full power, the power light stayed constant red and the lamp light was blinking red. The projector doesn't work anymore. Any idea what could be wrong with it?
Nevermind frank I fixed it! I forgot to mention I tried turning it on without putting the cover back on. It needs the lamp cover on to work. I'll leave my original comment anyway incase anyone else has the same issue 👍
Thanks so much!!
thank you!!!
Good video. Wish I watched it prior to disassembly of my Epson EH-TW 9200 where I remove lcd mirror cover with 3 ribbon cables and spray lots of air directly on lenses and mirrors. Now I have pinkish picture with green vertical stripes. Since you're experienced technician, do you think if I replace that part with ribbon cables (wich you strongly recommend not to remove), picture will return to normal?
Thats hard to say. You might have blown some of the coating off the prism or the green polarizer was damaged. I wouldnt replace anything personally. Epsons become a pandoras box of problems the more you dig. I'd double check the connections first. If that ribbon cable isnt pushed in all the way(even less than a millimeter) it will do what you describe. Id reseat the cables. If that doesnt help, I hate to say it but its new projector time. epsons are just a hassle to work on. I stopped taking them due to the amount of problems they turn into.
I wish I had something more positive to say, but thats just how epsons have ended up for me.
@@FixitFrank You're class. Thanks for fast answer. I tried reconnecting RGB ribbon cables (many times) without success.. Discarding PJ is also not an option (just bought it before Christmas on eBay for 800euros as replacement for my older Epson EH-TW 5200). My stupidity alone caused this since I didn't have to open it (have just 800hours) , but since I did this before to remove dust blobs on my old TW5200 I guessed some air blowing wouldn't do any harm. Boy was I wrong! Now I would gladly pay repair but here in Croatia we're lacking quality Epson service so I'm kind of stuck.. Hopefully will find some place to send it for repair? I could read on your other comments that you recommend DLP over LCD but I like it and in my case Epson would be fine if I didn't forced it to malfunction :(
Oh man, I hear you. I only recommend DLP for the longevity and ability to keep it running. LCD has a pretty finite life span. At least it becomes very expensive to keep running .
You may want to look at replacing the optic block. That is the prism with the 3 LCD panels installed. They are aligned to each other with the prism so replacing one is not really an option. I use a company in China called Time electronics. Gydz@timeprojectorlamp.com They are on holiday until the 28th though. Id send them some pics of the parts you want and they may be able to source used but good parts. You may want to replace the polarizers as well if they got scratched or damaged. If they are okay, then they can stay.
worse case there is a guy in the UK who might be able to work on it. I'd wait on that though since shipping might be a problem.
@@FixitFrank Bought (eBay) my older TW-5200, brand new from London, but since Brexit think that vat and customs combined would charge more than postal service.
Hello. The LCDs are the same or they are in different colors : r,g,b ?
This is a tough answer. Technically no but in a way yes. The LCD panels are not colored themselves. However they are labeled with each color and should be installed into the same color they are meant for. I am merely speculating that the LCD might be the same but need to be aligned for the color. I do not think they are made a special way to work with only one color. The color is determined by the Dichroic mirrors prior to the LCD panels. The light is already colored when it reaches the panels. If LCD was easier to align, I would try swapping panels with one color and another. I may have to try that in a future video. Thanks for your comment!
I have a Epson 84+ like the one you showed in the video. I know the bulb life is around 3,000 - 4,000. I have like 1,250 hours right now and the screen is extremely dim compared side by side to an epson incadecent projector. But I was told that the LCD in these projectors can go bad and I was never able to Google or find an estimate on the life of the LCD. Do you by any chance know if the LCD is the issue and also how long an LCD is expected to last before ?
Hello Stephen! I do not think the LCD is going bad from your description. You would see missing pixels(either all white or all black) or you would have lines and other constant image problems that are not brightness related.
Depending on the manufacturer of your lamp as well as the amount of heat the lamp experiences, can affect the life span. The lamp life rating is what to expect in a perfect situation. No dust, constant room temperature, minimal on and off cycles. In a normal situation I see lamps start to fail earlier the older the projector gets. This is due to the amount of airflow to the lamp being less as the dust builds up. The lamp gets very hot(as I am sure you know) and this causes the quartz glass to expand and contract with each on/off cycle as it cools. This takes lamp life away each time.
In your case I suggest 2 things to do. First is to remove the lamp and clean the projector out for dust. You do not need to open it like I did but you do want to blow some air into the vents on the inside of the lamp area to clean that lamp fan out. You can open it if you are comfortable of course.
Once you know the projector is clean, I would replace the lamp. Be sure you buy a lamp that at least has an Osram bulb if not an OEM(Iwasaki eye bulb). The cheap knockoff bulbs are not as good no matter how much they claim they are the same. Only Osram makes a replacement bulb that has the same type of dual (integrated) reflector to enhance brightness. Epson uses a type of lamp technology called E-TORL (imgur.com/BkhZqpl). Osram makes their own version of E-TORL. They are the only other company besides the OEM company (Iwasaki) who invented E-TORL if I recall correctly.
You should expect a pretty long lamp life after cleaning the projector and the image should be as bright as it was when it was new. If you have any other questions be sure to let me know.
FixitFrank thanks for the advice. Very helpful. I’ll try to remove that lamp and clean it to my best of ability and see if that makes a difference or at least hopefully brings a longer life to the lamp. I’ll probably check into getting a new lamp if the image remains poor. Thanks, stephen
@stephen Sure thing. If you are in the states, this place has them and you can return for a refund within 30 days if the problem isn't solved(plus a 6 mo warranty for replacement). www.purelandsupply.com/epson-projector-lamp_powerlite-84plus.html Use code P1265 for $10 off...(you didn't hear that code from me ;)
The main thing to look for is the Osram bulb or the Iwasaki bulb. I am not sponsored by the company I linked but I am affiliated. I only suggest them because I know their products well. Buy it where ever you feel is best for you. I dont want to seem like I am pushing that site.
What does the SCI header on the motherboard typically connect to on Epson projectors? I'm having trouble trying to reassemble a 5040UB.
Thanks Frank!
Thats usually the ballast control.
Hey! Great video! I currently am having problems with my Epson power lite S7... It starts up and then immediately says it's overheating... I assumed it was a bad thermal sensor since the projector was just turned on... Upon opening it up I noticed that one of the intake fans fail to spin on startup... Could this be my issue causing my projector to assume it's overheating?....if you have an S7 laying around to tinker with I would really appreciate a video!! Thanks!
The fan is definitely your issue. Immediate temp warnings almost always mean a fan that isnt spinning or isnt being sensed to spin (sometimes the Tach lead circuit fails and the fan still spins). In your case, I would replace that fan with one from the scrap unit if you can. If you buy a new fan, be 100% sure it is the same part #. Not just voltage and size. The RPM/Tach lead needs to have the same specs as the old one. That should solve it.
@@FixitFrank I'll give it a shot! Thanks for your reply.
@@FixitFrank Fan was the issue! It's running like a champ now! Thanks for your input and help!
@Cjb96 Awesome! Thanks for letting me know. Those fans are almost my first thing to check on a unit when the bulbs burst or when I get immediate overtemp warnings. Its almost like the manufacturer expects it to jam. Have fun and enjoy it!
