Question about Apple iMac G4 Desktop

1 Answer

My LCD display is basically black although the computer is still running. After talking to Apple, it became apparent that I would need to replace the LCD inverter. I have a new one purchased on Ebay. My problem is not knowing how to get into the computer to do the repair. Allegedly, I only need to open the display case, but I can't figure that out. Any visual or written advise? Many thaks, Philip

The screen on my Amazon Kindle 3G is partially white and partially black with white lines running through it. It has been charged but does not respond when I turn it on. Do you think it is worth fix


It's broken :(

There are companies who will replace the screen for about the same price as a brand new Kindle BASIC. personally I would suggest:
- buy a new Kindle BASIC for 59gbp;
or
- download any of the FREE kindle apps and just finish your library reads for free whilst you look around for a replacement.

If you want a TABLET rather than a eReader remember ANY tablet will download the free Kindle app so you can read your books on a Fire or a ASUS or a NEXUS or a iPad or anything really :)

Good luck.

My lcd screen is black


From what I can understand, if the camera is sill able take pictures but is not displaying any thing on the LCD, then it is a problem with the LCD or LCD cable connecting to rest of the camera or LCD driver on main board.

It can be as simple as a loose flexible PCB connection to the camera main board.

Check the caps on the power supply/inverter board first to see if it has any one of them with bulging/leaking tops or bad bottom seals.
See my pictures here (the caps in questions have my red marker on them).

To have it repair will not be worth it, you can DIY repir if you have all the needed tools and know how to solder.

Laptop will not display screen although is turned on.....


I assume you are saying the screen is totally black, not blue. If it is totally black there can be a large number of causes. It is hard to give one simple answer. It could relate to the brighteness of the screen, the display, the logic board, the graphics card or even a problem relating to updating Apple firmware, You could try some simple things first.1) If the lighting on your computer is accidentally turned all the way down, your screen will be black! To turn the brighteness up, push F2 on the top of your keyboard and click until the lighting improves and you see the screen. If your display stays black it could be an indication that you just need a new Display. They do wear out. 2) Another thing to try is to start the computer in Safe mode. http://support.apple.com/kb/HT1564?viewlocale=en_US As you push the power button hold the shift key down. This can sometimes help resolve issues relating to startups. Also, if your screen stops being black it is an indication there is nothing wrong with your display. 3) You could try resetting the PRAM http://support.apple.com/kb/ht1379, This can also help with a startup issue. 4) Some specific models of Macbook Pro computors have issues caused by the NVIDIA graphics card, which Apple knows about and apparently will repair, possibly free of charge. My suggestion if none of this helps is to take it to a Genius bar at an Apple store for them to troubleshoot. That, in itself, costs nothing. Other suggestion search with google for further answers from other Mac owners!
