i recently got CHA error , "twice" while using D90. Upon googling, Lot of people suggested that it can be card error but i have two cards and on both the times it was with diff cards. Moreover last time CHA was followed by an F-- error.
On the CHA error, i had to remove the battery as the CAM was totally jammed and was not respond even to switch off button.
Upon the F-- error i just switched off my cam and back on again and it was working fine.
In both the cases i carried out shooting with aboslutely no further issues and also the pics on the card was fine. It was a freshly formatted card.
Did anyone here face any similar issues. Any recommendations?
What should i tell the NSC, i can not reproduce the error at all.
