Laptop Screen Problem.
0
Hi,
I've been having problems with my laptop's screen for the past 2 weeks, and I'm thinking of getting the screen repaired (depending the cost). My screen (when booting up or when idle) will often times have a grey screen, sometimes with different tones of grey stripes. I have to move the screen back and forth to make it go away. There are certain times where the screen freezes, and again, I have to move it in order for it to go away.
Any idea what might be causing the screen problem? And how much would it cost to repair (If needed)?

You might try checking the video signal cable that runs from the mainboard to the display and the inverter connections that power the display. Because moving the display fixes the problem it sounds like there is a loose connection somewhere. Depending on you laptop model you should be able to find a manual describing how to disassemble it. Don't be to worried about damaging your laptop, just be careful and organized.

Connects to the rear of the LCD panel inverter board/FL inverter or the main board might be loose or covered with dust
You will need to remove the mask assembly which is the plastic outer border around the screen. If you are the type to be a little heavy handed and impatient, then this is not the task for you. Working around an expensive LCD panel is only for people who have the utmost confidence in what they're doing, the average LCD panel makes up 50% of the overall cost of a laptop and in some cases replacement costs are huge. (Be patient and use minimal force)
Be sure to remove all the screws holding the mask in place, normally expect to see approximately 4-6 screws. In some machines there will be only 2, the mask is also fixed in by snapping type clips that make it fit to the rear cover assembly.
Once you’ve taken that off, you'll have exposed the LCD and inverter which will both be connected to the LCD harness or wire loom that connects them both to the main board. Disconnect the inverter from the harness and from the LCD (the inverter will have a cable plugged into both ends of it) now.. here’s the thing. In a lot of cases your laptop screen repair is just a case of cleaning the inverter pins with some contact cleaner and this will fix the issue for a good while.
The reason is that the pins develop a film on them and lose good connection with the plug that is plugged into them, it’s a good idea to clean the harness plug as well. If you want to achieve a more permanent fix you will need to apply some Glue to the end that the harness plugs this will prevent the dirt film forming again on the pins over time. Once this is done the unit can be reassembled and it should be OK. If you have a faulty inverter that needs replacing the cost will vary from place to place Good luck!
