Coby Kyros MID7024 Front Screen Replacement

Giriş

The front screen on the device protects the actual LCD Digitizer from external forces such as weather as well as the surface for the touch screen. The protective screen lays flat inside the bezel on top of the LCD display. The protective screen is decently fragile and can become scratched, punctured, or torn. In order to repair or replace the screen the device will basically have to have all the internal parts of the device removed, from the back cover to the screen.

Place front bezel with protective screen flat on the table with the button on your left and facing downward.
With your left hand find the corner of the protective screen closest to you. It is the corner with an extra area of removed plastic allowing a place large enough for a thumb to fit in. There will be a thin black strip of padded tape in that space.
Use your thumb to carefully push the protective screen away from the bezel. The adhesive will give way little by little. Do this all the way around the area of the screen until the screen is removed.
Do not apply too much force as you may damage the screen.
