Someone replaced the screen and i added the wake/sleep part to it now it just flickers when i turn it on. Battery has 3.7 v on two legs and 2.4 volts on the other. If they’re not balanced could that be a problem? Also someone pulled hard on connector on the back of theLCD screen/panel and i did a fix to hold it down. Could not find where to get one from to replace it. Any thoughts ? ? Thnaks

Are you referring to the LCD display connector on the board being damaged? That is most likely what is causing the problem, if it’s physically damaged you may need to get it replaced via micro-soldering.
