some monitors have a plastic screen in front of the LCD to protect the LCD from damage, as its far eaiser to replace the plastic layer than the LCD layer.
Ah man, the world is so fucked. I actually laughed at the idea that a modern electronics manufacturer would not only include extra components in a design with the purpose of durability and repairability, but would also stock and provide replacement parts and/or offer repair services.
Name me a make and model of computer monitor on the market today that isn't designed to be thrown out and replaced at the slightest malfunction.
