My lcd cracked and won’t turn on. Now the led light is changing from dark blue to light blue and phone is unresponsive.
When the LCD cracks on a samsung phone it is very likely for it to not show any display afterwards. Phone is probably still on as you said the LED light is showing those colors indicated that it has booted and is displaying notification lights. Try getting someone or make a call to the phone and see if the phone responds. If it does then the screen needs to be replaced. If you want you can replace the screen yourself: You can buy the replacement screen from here: Galaxy S6 Screen Guide to replace the screen: Samsung Galaxy S6 Screen Replacement If you do decide to replace the screen, be very careful particularly near both the bottom touch capacitive buttons, you gotta make sure they are separated well from the screen (adhesive must not be sticking to the glass when removing screen)
Same here. The S6 has a pyrolytic graphite heat spreader so don’t just chuck away the old screen! For those who aren’t familar with it pyrolytic graphite can be used to make maglev setups among other things. Its also handy as EL substrate. I think the new ones do come with this preattached with tape and if you find a copper strip attached then the PG will be behind it. Unfortunately there’s no way to repair a cracked OLED panel as once water gets in it eats the polymers and this is why a broken phone often has no picture.
