thank you for your ideas, since still in warranty i phoned apple, they told me what to do, nick you were right about backing up and restore, since icloud was only giving 5g storage free i used itunes on the laptop. The instructions were, connect the ipad to laptop, put mouse over my ipad icon on Itunes in laptop and rt click. Then transfer purchases. This brought them on to the laptop before doing a restore. Next was, select summary tab, then select restore tab. When prompted to back up your settings before restoring select the back up option. Select the restore option when itunes prompts you, restore your IOS device, restore to factory settings, when restored, device starts, after a restore the device displays "connect to Itunes " screen. Then its restore your device from previous backup. Mine worked after this so hope this is useful for anyone with a similar problem. Nick and others thanks for your help, its much appreciated
