Question about Philips 26MF231D 26 in. LCD Television

1 Answer

Picture changes from color to black & white after 5 minutes

This started happening on Jan 1 after our Cable had been out for 2 days in an ice storm. It's not the cable-it is B&W on the DVD, too. When turned on, the pic is color, then after about 5 minutes, it changes to B&W and stays B&W for the rest of the time it's on.

This is probably a fault in the colour demodulator circuits. You would have to give the set to a properly equiped and experienced tech to service this for you.

My Mac G4 Tower, 10.3.9, suddenly lost all color. The display is black/white, shades of grey. When I start to boot up the screen starts blue but then goes to grey. This happened 2 days ago after a nearby...


The wether does have something to do with it. After a lightning storm humidity is a problem. the humidity and heat can make the screen lighter, kind of grey. After the wether clears up it will take an hour to regain full color. Also it could be if it was charging while the storm happened it could have blown a fuse and messed up you screen colors
Also try to gain color by

The picture is displaying in black and white rather than color. I switched to cable to make sure it wasn't the tv and the picture was in color. The system is a Sony RM-SS251


simple. unplug every thing. and wait 2 minutes before you plug back in. but in those 2 minutes, check your hook up connections by pulling them off. shuffle them around like dominoes. and then plug them back in. enjoy!

Dell 948 printer- won't print in black and white


I had this problem. It's actually very easy to fix:

- Click Print -> Properties
- Go to "Advanced" tab
- "More options"
- Deselect "Use color cartridge for all black printing"
- Select "Use black cartridge to print black and white"
- Click "Ok"

You should be able to select the "Print in black and white" option now and stop all the frustration!

Philips 50" rear projection- Washed out picture.



You need to change the CRT Fluid. This is a common problem on the  older projection TV sets. 
You can get the fluid and instructions on how to change it from www.TvRepairKits.com.

Here are the settings:

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.
