Just thought I'd share a few tips when working on electronics like laptops, TVs or tablets. Some of this may seem very obvious to most, but to those who are just getting started or have less experience, this may prove to be helpful.
First, make sure you have plenty of room and a fairly clean space to organize the parts. I usually clear my workbench of any materials that aren't related to the task at hand. Then, if I'm not familiar with the device, I'll do a little research on it (Google and Youtube almost always have some content you can learn from). I'll then gather the tools I'll need and make sure I'm not missing anything. Nothing like getting half way through a job and finding out you'll need to put everything on hold because your missing a certain torx screwdriver or some other non-standard tool.
Before you begin, take a few precautions. Make sure the device is powered off and unplugged from any power source including the battery if there is one. Also make sure you are discharged from any static electricity. Have an anti-static mat to stand on or wear an anti-static wrist strap grounded to something metallic.
Usually, the job will consist of taking the device apart to get to the internal workings. Depending on the device, this may consist of hundreds of little parts and screws. So next, as I start dismantling the device. I'll work out a sequence so that the first items I take off are the furthest away from me and then lay the subsequent parts in order from right to left as the space allows. Essentially, just trying to keep items in the order I take them off. This way when I go to assemble the items back together, I work in the reverse order and this helps keep things in its proper sequence.
And lastly, if you have a cell phone that takes pictures, it would be a good idea to take as many as necessary. Don't leave everything to memory. Take them at different stages of the process. Take them from a wide views and close-ups that way you have a reliable reference point.
Hope this is helpful to someone and hopefully you don't have any parts left over after :-).
