Joan, Check if your Flex 8 is under warranty, if you have to have it fixed by a tech., you will have to way your options to whether cost effective to repair, Flex 8 can be had pretty cheap now. I will post a link for tear down on your unit to enable you to access charge port and you can google search for a replacement part. Good luck.
