Repair help please

[scottishscott1967]

Hello all, I just replaced the lcd and digitizer on my sons Lg G2. It has like a back lit thing going on but will not boot to logo screen. I have taken it apart and put back together several times to make sure everything was as it should be. Every time, it was. I'm at a loss. I've always work on my own electronics and phones, but I cannot figure this thing out. Also, I'm used to working on Samsung's. Any and all help will be greatly appreciated. Thanks in advance

Welcome to Android Central. Perhaps the part is defective?

From here, it's like diagnosing "doctor, I have a pain right here" in text - can't do. You say "everything is as it should be", but evidently something isn't. What? Someone has to have the phone in hand to see. There's no special trick that LG uses that Samsung doesn't. (If you pinched one wire once and grounded the wrong point on the motherboard, nothing you do is going to fix the component that blew.)
