If all you need to do is change the screen then it WILL turn on. I have had and replaced the LCD on MANY ipod touch 4th gen and know this for a FACT. If it does not turn on after you plug it into a wall charger- not only is the screen bad but definitely the battery as well (at least). So, you should know that if you sell/give away as it is stating that it is just the screen and someone buys a new screen and it does not work, not have you only wasted every ones time and money for the person that bought it and a new screen, you will have to accept a return. Then it just becomes a hassle and all you will get is bad feedback and the loss of those credits........ all you have to do is place yourself in the winners position - you see how that would suck?? Do the right thing - either post EXACTLY what is wrong or have Listia remove it for you. Just words of wisdom and some advise. Hey, maybe you didn't even know these facts..... NOW you do. Take care my friend - was NOT meant as a bashing. Let's keep this a fun/safe and TRUE (as possible) SITE
