I have got many N series phone which are Dead and have no shorting. But when i supply voltage through voltage analyzer connecting on +/- and press on and off the voltage shows around 80-90 and when i release on and off then it gets hang at that same level (80-90). While in working phones the case is that when i press on and off the voltage goes upto 140-150 and when i release the on n off button it goes to zero. So please could you help me on the Hang problem. Which section is faulty that causes that problem.
