First you need to reset the PRAM:

  1. Shut down the computer.
  2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
  3. Turn on the computer.
  4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
  5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
  6. Release the keys.
Next you need to reset the PMU (power management unit). This will depend on the model of your iBook so follow the instructions on Apples page:

Hope this gets you going again

All the best

My sceptre lcd tv is displaying really bright pink and green colors


I had a similar problem with blacks showing up as green. Turning up the brightness a bit fixed it for me. Not a permanent fix, but something to try if you want to make it last a bit longer until you can get a new one or fix it.

Compag laptop connected to LG HD TV. TV screen just show blues and greens, no reds. What do I need to do


To troubleshoot this, you must first start with the obvious. Check your cable connections/try replacing the cable. If this does not work you should then check the color settings in the tv. If that still does not work you can try connecting your laptop to a different monitor/tv. If the color shows up with the same problem, you know the issue is contained within the computer itself. Possibly bad VGA/HDMI Port or color management settings.

Wire color abbreviations Isuzu Rodeo


P - Pink
LB - Light Blue
V - Violet
GR - Grey
LG - Light Green
BR - Brown
L - Blue
Y - Yellow
O - Orange
G - Green
R - Red
W - White
B - Black
Some wires will be allocated 2 colors ie B/W. This is a color with a different color line running along its length.
The first denotes the main color (Black in our example) and the second denotes the tracer line (White in our example)

Select your operating system. If this model has onboard graphics, download fresh VGA driver, remove your graphics card and see if you can get any results.

Different colors on the scanner screen


I didn't find a fix. I went to Best Buy and they said it would cost more than it was worth to fix. So I bought a new one. Thanks, mittenshadow
