[mikeestes99]

hello to all,
thanks in advance to all that read and try to help me,
replaced complete screen unit - LCD, touch, and outer glass
after replacing the unit and reassembling the phone the LCD will not come on.
what the phone does do is when i press the power button and only the lights under the home, back and menu buttons light up but go off as soon as i let go the power button. if i keep the power button pressed any longer the lights start to blink. when they start blinking they will go off as soon as i let go the power button if i keep the power button pressed long enough the lights go out on their own. after they do i release the power button and within a few seconds the vibrator cycles one time

i plugged the charger in and the red led light came on and stayed on for a good while then turned to green. i press the power button and only the lights under the home, back and menu buttons light up but go off as soon as i let go the power button. if i keep the power button pressed any longer the lights start to blink. when they start blinking they will go off as soon as i let go the power button.

so this where i am right now. please help if you can and thanks again
