Do not by any means clean the glass on a bulb or leave a finger print on it. If you dropped a new lamp in the dirt, blow it off with canned air. No amount of dust on the lamp will affect the image. Its most likely burn from usage.

If there is a dark spot in your image it is caused by a discolored reflector, dirt inside the optical path, faulty LCD.

My Samsung SCX-4623 F/X when and faxing has several. top to bottom lines


If you are getting lines on the faxes you send it means that the glass of the scanner is dirty. Best method to clean the glass is rubbing alcohol and a soft cloth. The alcohol will remove adhesives and white out better than glass cleaner. You may need to look closely because a small amount of adhesive will distort the scans and cause lines and may not be obvious unless inspected very carefully.

Picture looks 3d how do i fix


If you can access the three projector lenses you will probably find them covered in dust, this shifts the light slightly giving a blurry 3D effect on the screen. Clean the dust off with lens tissue and window cleaner or a cleaner made for glasses and this will restore your picture.

Projector had been overheating so we cleaned out the filter. When it was turned back on there was a loud pop. We turned off and turned back on, red lights started flashing and the fan roared loudly and...


The projector lamp has probably failed. If it had been overheating, the glass for the bulb would be weakened and then eventually when turned on the glass shatters, the pop you heard. Bulb replacement is usually a straight forward user replacement item. Ebay is often your best choice to get a bulb at a reasonable cost.

Many little white dots scaretered throught display


Yes you have dust particles inside the light chamber.
Remove the filters and clean them gently with a vacuum cleaner.
Used a compressed air can to blast air into machine and have vacuum (on Low) **** up dust.
You may have to take out bulb to do this (dont touch the glass on the bulb)

Just replaced burnt out bulb in Infocus 4805 projector. Great picture with new bulb but only black and white. Is this a bulb issue or something else in the projector?


This is most likely the color wheel. When the bulb blows, it can damage the color wheel. The color wheel is a wheel composed of thin layers of colored glass that spins in front of the projected image. It is possible to repair it with super glue, but the best way is to try to find a new one to buy.

Picture has a yellow tint. It's from an old video game that ran over 12 hours a day. Has new bulb. Except for the yellow, works fine.


Hello there:
The best way to describe this is what is called screen burn in.
this is very common on screns that have games or pictures that arre displayed for long periods of time without being shut down just like on a computer screen when a screen saver is not used .
there is nothing wrong with the bulb.
the yellow that you are seeing is actually burned into the glass part of the projector and the lense
so if you can and feel like you can dissasemble the projector dissassemble it and locate the glass and see if you can get the yellow tint that will be on the glass and the lense off by using some rubbing alcohol and a cottomn swab
But if it wont come off you will have to replace the lense and the glass ok
Hope this is very helpful for you
Best regards Michael

Compressed air Vs vacuum cleaner for filters?


don't clean with compressed air, you will contaminate the air you breathe. I just bought a small ShopVac with an 18-foot hose to clean exactly what you're describing

Cleaning better than self-cleaning


What you have read is correct, the catalytic lining can be damaged by corrosive sprays. It should be safe to use 'Easy Off ' on glass though.

The standard Auto clean cycle is the best method of cleaning that i know of.
