Windows 7: LCD smudges?

LCD smudges?


While trying to replace the CCFL, I noticed a few smudges, on the borders of the screen, specially noticeable when a blank browser page is opened.

Are they caused by spot on the sheets, if yes can they be cleaned or do I need to get the sheets replaced?

OR are they caused by a faulty invertor or incorrect CCFL?

1. Is it possible to know the details of the LCD, without opening?

2. Like invertor specs, CCFL specs?

3. How many polarizer sheets are there in a LCD display?

I have no idea what you're referring to with ccfl
But any lcd display/ monitor might have dead pixels and might be what you're noticing with a blank page ?
