I  try  the  Pisen  the  one  it  came  with  but  no  go. I  have  the  dx90  still  on  do  you  think  I  should  take  out  the  battery  turn  it  before  it  drain  down  again .  I  dont  know  what  to  do , maybe  i'll  sleep  on  it  and  come  back  tomorrow

yeah  it  was  great  4  days  ago  I  bought  it  at  B&H  here  in  new  York  one  the  best  audio  store  anywhere .  do  think  because  I  let  it  drain  completely (  battery )  that  this  happen  the  replacement  battery  was  a  anker   I  just  dont  get  it .  

don't  have  another  sd   card  I  took  the  battery  out  because  that  the  only  way  it  can  turn  off , put  battery  back  in  and  power  it  on  3or 4  sec.  it  click  when  I  turn  it   on  and  nothing  happen  no  browes  or  scanning  window  just  dx90  logo  .can't  go...

I  took  out  the  sd  card   and  press  the  power  button  for  about  8  sec.  and  it  click  than  turn  off  it  click  again  and  come  to  the  dx90  logo .  I  only  had  this  for  a  month  and  half  and  still  on  the  dx90  logo
