LCD screen wearing?

How does a laptop's lcd light wear out? If it does wear out does it have a bulb that can be easily replaced?

I have a z60m which is of the widescreen variety and I just want to know what to expect and do when the times comes.

The bulb that you are referring to is called a CCFL, or backlight. From firsthand experience, I can tell you that it is a nightmare procedure. Some have changed them relatively easy, but on the two occasions that I tried, I broke the bulbs. (they are very fragile)

I would expect that you shoiuld get a great deal of life out of your LCD. I have a perfectly working 701CS from the mid-90s and it is still all original.

@tfflivemb2,
Can you show me a pic of that bulb? I think i would rather change it myself than to allow the technician to do it for me as this will cost more than a few dollars in Singapore. How would you go about taking out that bulb from that LCD panel? Can show me? Thanks.

I would use this as a reference.

It isn't easy to do yourself. You can have moniserve do it for you for a little over $100USD, depending on the size of the screen. There are pics of the bulbs there, as well as in the tutorial above.

This should explain very well how a CCFL tube works.
