LCD not turning on after switching logic board

Hey there. i'm currently working on two IPhone 6's, and was testing out what would happen if i switched the logic boards. I switched the logic board on IPhone 1 to IPhone2 and vice versa. However, the LCD of IPhone 2 wouldn't turn on, however it could still be found via itunes. The LCD on IPhone worked as normal. When I switched the logic boards back however, the LCD on IPhone 1 no longer would turn on while it could still be searched via itunes. So i'm wondering is there something i am doing wrong? Could it be problem with the mother board itself. Could it be not putting screws in the right order?

Logic circuitry....ahhh what a headache it can conjure from a well placed plan.

If your certain that you have made all the correct connections and screws and so forth, Pull the battery.

And leave it out overnight. Logic circuitry is composed of thousands, tens of thousands, well a lot of micro capacitors. These are for the purpose of filtering, charging-discharging ect... It is not unheard of that when your doing what your doing, the charge states could get mixed up across the circuit and in a way create confusion to the other parts. Hard to explain.

I had a graphics card years ago that was a high end card. $300.00

I was experimenting with overclocking it and, well, the screen went-gone. Blank!

I was hoping I just overheated it some and gave it some time to cool.

I shut every thing down for a while and powered back up and....nothing.

Schux!

Fried my good card. Put the old card back in and thought maybe Best Buy might honor it as defective.

A few days later, I finally was going towards that part of town and I had the card already in the car and...I, thought..maybe - try it one more time.

And well, it worked. Worked fine.

I have had this happen before with other things composed of logic circuits.

Remove all sources of power and let sit for........a day, two, I don't know. Just long enough to let the micro-capacitors to slowly drain to nothing.

Any one who thinks differently apparently has much too discover yet.

Not that this is the solution but is a simple procedure that can be tried by the most unskilled of unskilled...not that I think your unskilled!

It takes skill just to have faith in your self to do what you are experimenting with. Keep it up!!!

Okay thanks for the advice. I've taken out the battery and power sources, and am going to leave it for a couple for days.

Question, when i did the switch last night, i left the iphone 3 hours plus on two different occasions out of frustration, and when I went back to trying to figure out what was wrong, the screen/backlight would come one for a second, but then it would go back to black. Would that be a problem in someway.

Try disconnecting the battery before you swap the digitiser. Sometimes this helps the logic board recognise the new screen.

Is it the singular LCD you are having issues with or is it the logic board? The Phone will be recognised by iTunes regardless of a digitiser being present. Im slightly confused after reading your original question more carefully. I am making the assumption that both LCD's are working and proven to be so?
