Question about Optoma H30 Multimedia Projector

Noisy colours/dark shading and colour banding on Optoma H30!

When watching a dvd certain colours or foggy scenes have a lot of flickering specks and scenes where a colour is supposed to bend into another colour (picure a sunset that is dark at the top and gradualy gets light near the horizon) there is colour banding or stepping. Like bands of differen shades not smooth shading. I've tweaked and used Digital Video Essentials and tweaked again and I very frustrated by this. PLEASE SOMEONE HELP! I did send it in for cleaning to optoma and since the the pic quality has gone down hill! I have an Optomoa H27 which has the same color banding issue. When I got a new bulb, the banding appeared after an hour or so. Now after 1000 hours on the bulb, the banding appears after 15 minutes. I have carefully removed all dust and lint every two months. It doesn't seem to make any difference. I have also reset the settings on the projector. Again, nothing. Any ideas or suggestions would be very appreciated!

    Hi WelcomeJee,

    thanks for the suggestion. I did as you suggested (disconnected cables, reconnected / reset all settings / hit resynch button). Still get the color banding after 15 minutes.

    Next steps?

Please perform "Reset All" function in projector Menu to set it on factory default settings. Connect dvd player and press Re-Sync or Auto Image on remote to get good picture quality.

    About the first problem, band appearing and pixelation, if this happens on all dvds then it is a derty lens buy a dvd lens cleaner and it should fix it.
    about instad a color band appearing when bulb is hot , it may be a defective bulb, or a problem with color wheel.

    If you get very bryght colours behaving erraticly, then definitively you need to replace the color wheel.

Optoma H30 Projector: color banding


Most DLP projectors have a colour wheel. It's usually hard to get at, and you may have to actually remove everything including the optical block from the projector to access it. This wheel turns on a motor just like a fan, and if it gets dirty it can act up just like a fan.

They are expensive to replace, so you might want to try taking it apart and cleaning it out. Add a small amount of 3 in 1 oil to the motor if you can.

I have the optoma h31 projector and the color turned purple. We assumed it was the bulb and put a new one in. The color is now still not right and the picture sorta bounces


I had a similar issue with my EP739, the problem would start after about 3 or 4 minutes and then get gradually worse and worse..
The most strange thing I noticed was that white looked fine. And if you opened the configuration menu in the projector it appeared that blue was labeled green and green blue..
Some sites suggested cleaning the machine of dust, which I tried using a can of compressed air... This did not fix the problem at first.. but when I had it apart I studied the colour wheel for a little while and wondered if some how the machine was synching to it incorrectly somehow.. So I blew out the colour wheel location sensor (It's kind of obvious being the only component mechanically connected to the color wheel. Much to my delight, this fixed the problem...

So my solution to the flickering / colour fading / colour swapping issue with DLP projectors was to clean out the dust from the colour wheel location sensor..

In fact, if I did it again, I would ONLY clean the sensor, and leave the rest of the dust alone. Blowing dust around has the potential to cause other issues, especially if it winds up inside the optics system.

Try # 2... Green Fog


The green gun in your picture tube is set a little too high. If you are experienced in removing the back cover of TV's,etc., you may try to find the drive and/or bias controls either on the circuit board that plugs on to the neck of the picture tube or mounted on the main circuit board of your TV. These controls are usually labeled. If you can find them, locate the green bias or drive control and back it down a little while watching the picture through a mirror. A slight adjustment may correct your problem.tJIS IS CALLED GRAY SCALE ADJUSTMENT. BE CAREFUL THERE ARE SOME HIGH VOLTAGE CIRCUITS NEARBY. WORK WITH ONE HAND AND USE AN INSULATED TOOL TO MAKE ADJUSTMENTS I hope this may help you.AGAIN BE CAREFUL!! Stargazer

could be an intermittant connection on the picture tube curcuit board,or a bad picture tube, a bad flyback xformer,or a bad b+ capacitor off the flyback that controls the driver transistors on the crt board. Good Luck
