Screen flickers when plugged into AC power, no boot.

I have the same problem I have tryed and got the iPad to power up by using a higher amp like 5v 2.4amp cube or same power out put with usb connection,that’s when for me it went to the blue apple iTunes logo and can reset with no luck comes back to iTunes logo.it will turn right off if unplugged. Computer port will Flicker because only 500ma for power coming through USB connecting on standard so not enough amps to power it up.thing of using and independent powered data hub next. If I can keep power 2amps on 5 volts going in the iPad it would work to reset os.i think its the battery. When set into recovery mode computer will recognize but when trying to re-install OS it shut power to USB which canceled Install because power to iPad stops and iPad shuts off.now no power and a1600 error comes up it’s a usb problem wich means when the computer tried to disconnect then reconnect it lost power to Apple iPad.

iTunes will connect and reconnect multiple times before install that’s where I’m at now I think it’s the battery.these battery’s are only really good for like 3 to 5 Year’s decreasing from like two years on.if iPad has been put away for long periods Of time the battery will decrease little by little because of microchip safety with battery.

Same problem..but inuped the power supply. To a apple power supply now no blink its stuck on the apple. What next.

Did you happen to find out whats the problem?
