Set your header image in the stylevar manager
AdminCP/Styles and Templates/Style Manager/Stylevars........scroll down to titleimage under Image Paths and set the URL there to your title image.

create another default style , then you shouldn't have this problem again!
you can also fix this by reverting template >> NAVBAR

i tested same i can reverting is already revened but not work please cheak http://www.indianweb.tv/forums/ please help me buddy

your issue is with following line which ads a border of size 10px around your navbar :
you really need to remove it or at least change the border size to 1px instead of 10px
you can find it in your css files ( by doing a search through admincp >> styles >> search ) or if not , by looking for it in styleVars
