Today we are going to remove and replace broken display hinges on Toshiba Satellite A20 or A25 laptop. Replacing broken laptop hinges is a very time consuming repair because you have to take apart the laptop base and the laptop display. This guide has a lot of disassembly steps, so make sure to memorize the disassembly process. For all removed screws I usually use plastic caps. I mark these caps by layers: bottom, keyboard, under keyboard, system board, LCD mask, screen, etc. You can use your own names. It also would be very useful to make some notes so you can use it when assembling the laptop after the repair.
Here are the left and right hinge part numbers for Toshiba Satellite A20 and A25 laptops:
Brake hinge, right: P000378510
Brake hinge, left: P000368300
You can search for these parts on ebay on via google. Be prepared, hinges are very expensive.
