Having problems with your PC Laptops ?

When I open my laptop the screen becomes green and fuzzy. This is until I move the screen slowly backwards and eventually I hit a spot where it comes back to normal but if I move the screen forward or backwards it goes green and fuzzy again. Seems like the longer this problem persists, the further back the screen has to be in order to correct itself. Any help appreciated :)


Answers :

The ribbon cable to the lcd layer (green pixel contact common) is going bad or the connection of the cable to the lcd unit is dirty. It is probably the connection, as the ribbon cable, if installed correctly, will flex many more times than the hinges would be able to (that is, the ribbon cable should outlast the laptop). Sometimes they might not be installed correctly in that there is a hangup or kink of some kind and the bending (each time the laptop is opened and closed) makes it bend beyond the elastic limit of the metal, and it eventually cracks. The problem you have may be cause by the cracked metal in the ribbon cable, and careful placement of the screen makes the cracked trace reconnect by flexing. It could be caused by a bad contact of the cable to the board or (most likely) the screen unit.\015\012
\015\012If you are inclined, take apart and carefully inspect the ribbon cable for any parts that have a kink in it or is otherwise flexed too much in one small little area. Flex the cable to see if it changes the display. Otherwise, wiggle the ends (careful) to see if it will try to work. \015\012
\015\012If you find a cracked cable, have it replaced. If the contacts prove to be dirty, unplug or otherwise remove cable end that is dirty and reseat cable after carefully burnishing contacts and using contact grease (smathering only).
Your lcd cable has a short. You just need to replace it. Every laptop is pretty much the same.

Here's a general guide for what to expect.
