iMac G4

Originally known as "The New iMac" the iMac G4 was created to replace the iMac G3 as Apple's all-in-one desktop computer. The G4 is easily recognizable by its swiveling monitor mounted above the hemispherical computer. Steve Jobs quoted it as being "a design that will last till the next decade."

Replace the Screen Backlight?

I have a G4, 1.25ghz, 20inch Imac with a blown backlight. How complex is it to fix this myself and what are the approximate cost of the parts? I am getting estimates of over $1000 in the NYC area to fix this.

Answer this question I have this problem too

Is this a good question?

You would need to partially dissasemble the screen assembly by removing the hex screws around the display. Then, partially lift the panel out, and disconnect the LVDS cable, and inverter power cable. Then remove the LCD Panel/ faceplate. Then you can disconnect the inverter and replace it.

So is the Inverter another name for the backlight? I think they said the backlight bulb is what blew out. Where would I source the part(s). Thanks in advance.
