Question about Optoma H30 Multimedia Projector

14 Answers

Optoma projector We are having problems with our projector. The screen (or light bulb) flickers. We have had it just a little over a year and first the colors got funky so we replaced the bulb. Now when we try to watch it(we use ours as a television), the screen flickers. Not quite sure what all to try. We have tried the resync button and that does not fix it. Any suggestions would be great!!

    We have an Epson PowerLite 54c that starts to flicker after it has been on for an hour. The screen will flicker with or without a computer image. Tried to synch but that did not solve anything. Is it the lamp or some other problem?

  • krajeeva Oct 25, 2008

    Hi, I have the same problem with my Optoma HD70 projector. After running it for around 30 mins, the screen starts to show flickers of green. It gets progressively bad and in the next 2 mins, it will completly turns green and the lamp LED starts to glow. Any help to fix the problem will be highly appritated.

    Wiggling the wire from the computers screen output makes the colours do funky. so I bought new connecting computer leads and they are worse- i get very bad quality pic from a DVD. The boulbs only done 700 hours- so dont think its the problem.

    I have or should I say had the same problem with my hd70. I noticed flickering after just 4-5 months use just watching television and the odd movie. Tried the very first solution. Couldn't figure out how to get the back off so tried jetting it out with my air compressor and eureka it worked not even a flicker of a flicker thanks. Kevin from Birmingham.

DONT THROW AWAY YOUR BULB JUST YET!!! IT MAY BE THE COLOR WHEEL!

I have an optoma hd70 and was having the same problems. I also tried the "dust blob" tutorial, but unfortunately it did not work for me (and I ended up getting dust on the lens I couldn't get off myself). I started searching on the net for more answers and found some information regarding the angling of the projector. Apparently, if you tilt the projector with the back raised too high, the ventilation system does not work properly and this increased amount of heat damages the color wheel inside (this causes the wheel not to spin correctly and display a flickering effect...and that's also why it works for a few minutes on start-up but then gets too hot and the wheel skips and creates the flicker).

Luckily, I have a very extended warranty and was fortunate enough to send it in and have the dust removed & color wheel repaired/replaced. Now, I've lowered the stand for the projector to not have it tilting at such a high angle and haven't had any problems yet...but it does take awhile to get effected (had mine for about 1 & 1/2 years)

I know I should have probably just sent it for repairs in the first place...but who wants to miss out on having a projector for two weeks when a tutorial says I could've fixed it in like 20 miutes?!?! Oh well. Hope this helps someone...good luck;)

Thank you oh thank you oh THANK YOU!!!!!!!! I have an Optoma EP759 PRO that is used stricktly for home theater. It is about 2 years old. I have been having flickering problems for several months now and have replaced the bulb 2x in 3 months. The 1st bulb was a genuine Optoma bulb and the 2nd was a Phillips. The flickering still continued and got progressively worse till finally the set wouldn't come on at all and if it did it would shut down after 5 mins. I was looking for a repair center on line when I came across this site. I couldn't believe that the problem could be dust as I regularly vacuum the vents. I decided to disassemble and blow out the projector with compressed air befor sending out the unit and low and behold, it works perfectly now. No more green start up screen, color is fantastic and NO MORE FLICKERING. You would not believe the amount of dust built up inside and on the 3 fan motors. It is like new once more and I have an extra bulb. Ican't believe it. Thanks again!!!!!

I have a Optoma HD20 and when I turn it on the screen is green and the image is blurry and flickers.....but if I leave it on after 30 seconds a squeaking noise stops and the picture goes back to normal. Is this the color wheel, or dust?

    I also have an HD20 and similar problems. I blew the dust out with an air compressor and reset the unit. That did not fix the problem. Taking advice about overheating I changed the fan setting to "high altitude" which makes the fan run faster and louder, but it has made the picture acceptable, but not as good as when it was new. Also, I only have about 600 hours of viewing time on mine over about 3 years.

I realize this is an old thread however I had the exact same issue with dust blobs on my HD70 and was unable to locate instructions or a tutorial on how to remove them. After reading forums on tons of people having the same issue, I figured I would try and fix the problem and create a tutorial for everyone. Please check out my blog at http://tantht.blogspot.com/ for instructions on how to remove dust blobs from a HD70 as this process worked perfect for me and I no longer have these annoying spots when watching movies!!

My hd70 started flickering around the 1800 hr mark and i always ran it in eco mode, thought i would have gotten at least 2500 hrs. anyway, replaced bulb and after a few days started flickering again after an hr or so being on. thought bulb was faulty so bought another bulb and flickered almost immediately after i turned it on. to bulb out and used my shop vac and a can of air to clean out all vents.  after a year (bought it new) you'd be surprised how much dirt it collects. anyway, cleaned thoroughly, replaced bulb and remounted.  haven't had the problem since, at least for about 3 months now.  keeping my fingers crossed.  hope this helps.

Crazy, but its true!
I just bought a used Optima EP 758 an to my dismay a horizontal white lightning bolt flickered across my screen about every 15 second...after hours of setting it up! I found this blog and pulled the unit off the ceiling shaking my head in disbelief. After carefully unscrewing and pulling the case apart...sure enough, DUST! not a lot, but plenty on the fan wheel and on the inside of the case. I was too nervous to use my compressor (Especially at 90psi, enough to drive my framing gun) to blow it out, so I just used canned air and gently wipe EVERYTHING with a clean white (Easy to see what you picked up) undershirt (Thinner cotton). Put everything back together an WALLAH! FIXED!!! ...Crazy, just crazy!
Thank you for the fix blog

Yep, it also worked for me, on my Optoma EP716.
OptomaUSA wanted me to ship it to them to get it fixed, (I'm in France)....
and since it was not under warranty anymore, I decide to take it apart and clean it.(dust it off)
Which totally solved the problem!

Thanks so much for the tip, it was very much appreciated!

The Solution above works. My Acer PD525 would work great for about five minutes then start flickering, Changing to drap colors, and turn off. I replaced the bulb and still had the same problem. Thanks to this thread, I opened the box and dusted. It has been working great for 48 hrs and still kicking. Who would have thought dust would cause it to do that. Thanks so much. I was about to buy a new one because Acer Tech support is non existant unless you want to pay $2.50 a minute. Even if i had gotten a hold of them they would have had me send it in for repairs. This thread has saved me at least $1,000. Thanks again!!!

In focus 70+ light flickers


I have the exact same problem, it comes and goes, but i noticed that the screen was flickering more when the projector was tilted up a bit.
I shifted the cable from s-vhs to vga and now i dont have this problem so often anymore.

I also have the common problem that it sometimes wont start up when i power it on, or it shut down after a few seconds. It seems to be a loose wire somewhere, but i just give it a punch and then it starts..

Image flickers and colors off


I have the same problem as philvo. I was watching, the projector was operating normally, I heard a snap, there was a flash of light behind me I believe, and my Mitsubishi XD300U projector went to a black and white picture. That is all it will show now. All lights show normal operation. I would like to know if it is worth getting repaired. Does anyone have any ideas?

My projector won't come on.


I answered this question many times. This is caused by a failed color wheel sensor. It faile gradually, first the lamp flickers, sometimes go dim for no good reason. Finally the lamp will not strike and you will get two red warning lights. I am factory trained and I stock the redesigned senor.
