It sounds like the touch screen digitizer has been damaged. Not sure if for this device you can replace just the touch part or you have to replace the LCD/touchScreen all in one piece but it sounds like if you get the screen replaced it should be good as new. Also the innards won't fall out so connect it to the keyboard. If the keyboard and mouse still work the you can either not use the touch screen or just get the screen repaired
If there is a way to change keyboard settings it will probably either been in the control panel under devices or accessibilities. Look up how to turn on/off "Sticky keys" in your version of whatever OS you are using
Make sure that the device is off (take out the battery ASAP if possible). and let it dry for a few days. If you can take it apart, get out any water, and leave is open to dry that would be best. there are ways to make it dry faster/better like putting it in a container with a thing of damp rid or any other desiccant (don't let the desiccant get into the device though,desiccant can suck the moisture out of the air which will draw more water from the device into the air and so on)
It may have a bad optical drive. I had a friend accidentally kick my once and I just replaced the optical drive and it was as good as new. Do all the disc you put in say that and does it still work with games you download?
The lcd and touch screen are 1 part. you can either get the "Galaxy S III LCD Screen and Digitizer (no Midframe)" which requires a little more work by transferring some pieces from your current screen to the new one or get the "Galaxy S III LCD Screen and Digitizer" which includes the mid frame but cost a little more. The description of the "Galaxy S III LCD Screen and Digitizer (no Midframe)" in the iFixit parts store explains what it does and does not come with
If your TV is plugged into a working outlet and/or surge protector and you don't get any indicator lights or indication that any part of the tv is receiving electricity then then TV has probably blown an internal fuse or the power board and been damaged or gone bad.
Sorry to say that there is no way to repair a ripped cable. You can replace the home button by itself but the touch id won't work. If you won't touch id to work you would have to purchase "iPhone 5s Logic Board with Paired Home Button" which iFixit sells in the parts store
I have attached the specifications and service manual as well as 2 photos 1 to show you where the wifi card is and 1 to show you what the slot I think you are talking about is. Also, are you using wifi or hardwire ethernet. What do you mean by "it says it's connected" what says that, and what does it say it is connected to? [belge: ] [belge: ]
