Hello, @KALMASOODI . . . at this age, your EMO is off warranty for replacement or repairs by Support; however, they may be able to diagnose the issue and tell you what you would need to repair EMO yourself or have someone you trust repair him.
You can let them know the issue, his age, his I.D. number when signed into the app and get video of your attempts to troubleshoot the problem, and send the link along with this information to service@living.ai to see what they advise.
There is a thread with tutorials on making repairs here, but be sure if they advise you to get specific parts that you ask them if they could provide them to you and what the cost would be or where to obtain the parts yourself.
My best to you.
