Hello. I have a problem on my Lynx. When powering up, the red led goes on, the common speaker powering sound can be heard and the backlight goes on (all seems to be right) but immediately all the system goes off. then consecutive press on the on button does nothing until I wait for a time or I press the off button and then again the on. Does anyone have a similar problem or know where to start looking? Thanks a lot.
