Here is a video that shows you how to take the SGH-t629 apart. I had the same problem, my screen would first invert, then it turned all white. I just disassembled mine and it looks like the flex cable got a small cut in it some how probably from the sliding mechanism.
good luck!

I cannot hear anything, not someone on the other

The problem is either in the speaker contact pads or the speaker itself. If you have the tools to disassemble the unit check the contact pads, clean it and lift up the speaker terminals to ensure it makes contact with the pads. If it doesn't work, check the speaker resistance using an ohmmeter. The resistance reading should be 20-30 ohms, otherwise replace speaker.
In addition, sliders use flexible ribbon connectors that may wear and crack over time. Check also this connector on your phone if cracks are obvious. You need to replace it then.

Phone stopped working suddenly

This sounds like a flex cable issue. You will need to have a tech examine the device to see if the flex cable needs replacement.

The flex cable is the ribbon cable that connects the screen to the rest of the electronics and allows the slider mechanism to slide and have the device maintain proper electrical connection. After two years it may very well be worn out.

Keypad settings

the only options Ive found for this are if you hit a button with the slider closed it asks if you want to unlock the keypad. Then you hit the right top button (says "ok") and it unlocks...this stays like this until you open and then close the slider. This is the only way I know of to unlock the keypad, I have not found any other way in settings menu or anywhere else. Good luck!!
