BB 9700 bold wont turn on after replacing LCD.

My lcd is cracked so i decide to check what kind of LCD I have. Therefore I opened my device and unplugged screen, wrote down the numbers and reassemble everything back. I did everything according to this tutorial BlackBerry Bold 9780 - 9700 Disassembly - LCD Display Screen Repair & Track Pad Replacement - YouTube.

Now my phone won't turn on. When I put the battery in, the red led is on for about 15 seconds and then turns off. If I try to turn it on, the keypad is highlighted but the screen is blank. I charged it for about 2 hours but the problem remains. I also tried putting in and putting out the battery while the phone was plugged into wall charger.

hi there, welcome to CrackBerry! Have you actually put the new one in?

No. I just checked the numbers and reassemble. Recently I managed to turn it on (blindly). Before taking it apart the lcd showed some image but now it is completlely blank. Do you think putting pressure on screen while removing it might cause it? I was going to buy a new screen but now I don't know if this manfulction is caused by screen or maybe I damaged something on mainboard (I was very careful during whole process but you never know).
