PDF problem on Sony PRS-300
I converted many books on calibre to PDF format that my friends gave me, i out it onto my sony reader but when i start reading sooooooo many pages are blank, like half the book is???? but its fine on my computer?? does anyone have a solution to this?? most of ebooks are pdf??? and i just bought this reader, i dont think its faulty because word.doc, epub and bbebb book work fine???
p.s also does anyone know if this model reader has a backlight??
