replaced midframe and digitizer/lcd no image, only backlightpleaseread

i replaced the midframe and the lcd,digitizer combo. I have done this a thousand times with no issues.

it is an iphone 4 gsm

the backlight comes on but the lcd doesn't show anything, my old lcd worked before so i changed it back and hooked it up and still nothing with the old working lcd connected. I then used a third one and still nothing.

the connectors look fine, i hooked and unhooked em 20 times same with the battery with time in between.

i tried the hard reboot and still nothing

i get no response out of the digitizer but my phone will do voice control

any info will help please, like i said i hooked and looked alot and seen a million people online only say that. please let me know something. thank you

It is possible you damaged the video output on the logic board by accidentally knocking off a resistor. I would suggest get a 10x to 30x magnifier and look up a diagram of the logic board and do a thorough inspection of the resistors, connectors, etc.

It is very easy to bend the lcd cable in the frame when installing the front glass. Pinching it between the glass and the frame will cause this to happen.
