Help RE T21 Screen not working and how to dismantle

[lemonfresh]

I am currently tying to fix my Dads T21 which has recently had problems with the screen.

Apparently for a while the screen would not not work when turned on unless you moved the lid back and forth in a certain way, and now eventually it has stopped woking altogether. I wonder if anyne has any ideas, to me initially it sounds like it might be a dodgy connection between the screen and the laptop.

I have removed the obvious screws but cant work out how to get inside the laptop, and wondered if anyone knew where i might find a guide on how to take the case off,

Also if anyone has any ideas of what the problem may be, that would be greatly appreciated

Many thanks in advance

Hello,

I think this might be caused by either a loose connection between the ribbon cable that connects the LCD to the motherboard, or by a deffect in the cable itself.

You can take some pieces of the T21 appart. You need the Hardware Maintenance Manual. Download it here:

Good luck with it.

Ok so i have taken the case off altohugh i did not take apart the lcd assembly entirely,

i now get an image on the screen put there is no light shining, so the image is too dark to see, its like he ghost of an image. I think therefore the backlight is not coming on

I wonder if this is controlled by a cable that i may have knocked loose, or if it is something more complex

If anyone has had a similar problem etc id be grateful of any clues
