Replaced broken lcd screen with a new one and now theres no display on the lcd screen

[morgancrx]

My mogul has never been flashed, the rom is the original sprint rom. I rechecked all the cable connections 3x. I put back in the old broken lcd screen and it does the same thing as the new lcd screen. My phone responds to touches of the screen (led lights get brigther), but gives no picture. Windows will also reconize it when plugged up through usb.

Do i have to take out the tiny internal bios battery for it to recognize the new lcd screen hardware? Or do i have to flash the rom?

Been searching the forum for a few hours now with no luck, please help =)
