A recent study shows that with all the smartphone, tablets, and computer screens we have around us, the quality of our sleep has really started to decline. The number one suggestion? Put down that cellphone. The LED screens are keeping your brains awake.
Adonis wants to know how to best clean his computer monitor. Leo says he'll want to be sure to avoid alchol based cleaners, because they could strip the sensitive coating. Leo recommends KlearScreen. A damp microfiber cloth will also work just fine.
Doug has a laptop and he can't see anything on the screen. Leo says there are a few things that can cause that. First, he should shine a light on it. If he can see the faint ghosting of Windows, then the backlight in the laptop has gone bad. It could also be that the ribbon cable that connects the LCD to the laptop has broken. That's an easy fix. If his laptop has a video out connection, he should try connecting it to an external monitor. If he can see Windows then, he will know it's a bad screen. The motherboard may be bad, too.
Larry has a 7 year old laptop, and its LCD screen died. Leo says that often with laptops, the backlight goes out. If he uses it outside, he can adjust the angle to see something. If it's all black, then it's likely that the ribbon cable has finally broken from the frequent opening and closing. If he has a monitor with a VGA port and can plug it in, he can still use it as a desktop.
Another problem is the power supply. But after 7 years, they're really not worth repairing, especially since Larry can get a Chromebook for about $200, or maybe even an HP Stream.
A lot of computer screens still use plastic, which is something you would not want to sand or try buffing because it's very soft. More and more computers and devices now use have glass protective covers. The LCD screen is beneath the glass on a phone, laptop or iPad. Generally speaking that glass is going to be something called gorilla glass which is made by Corning. This glass is very tough, which makes it harder to scratch but if it does get scratched, it's also harder to fix.
