Hi
Good day
Look for 1) flat or Ribbon or Flex Cable loose between Screen and CPU board and clean Edge connector with Electronic Spray Contacts.
2) Measure Lithium Battery if is under 3.3 Vdc.

 

Thank you for your reply.
We've all checked the cables and we've put them together again.
Battery is new 3.6 vdc.
The machine still can not be started.
Is there any more possibility?
We tried everything and still nothing happens and we still don't know what the problem is.

 

Please put Attention to this:
CPU board +ALL boards C lean Edge connectors withElectronic Spray Contacts.
this is the cause of Most terrific problem in Electronic.
