In org-mode, Latex previews are not loaded at startup when using #+STARTUP: latexpreview. I've also tried customizing org-startup-with-latex-preview with no effect. Only way to preview latex fragment is individually doing so by using C-c C-x C-l
As example I'm using the following org file:
#+STARTUP: showall indent latexpreview entitiespretty
* dfs
* df [2/2] :prb:
- [X] sdf
- [X] sac
* LaTeX embed:
** \gamma \alpha \beta \theta Caracteres especiales, renderizados con: C-c C-x \ Se hace permanente con #+STARTUP: entitiespretty
** Subscripts M_sun ( =M_sun= ) | Superscripts 2^2 ( =2^2= C-x 8 RET hex RET)
** $a ^2=b$ Previsualizar con =C-c C-x C-l=
** Previsualizar con =C-c C-x C-l=
\begin{equation}
x=\sqrt{b}
\end{equation}
Edit: Following tobias advice I checked with emacs -Q which seem to work, but now, I don't know what is it in my emacs init file that is making the previews to fail. Next is my init.el file:

C-h v org-startup-with-latex-preview RET, what does it say the value of that variable is? – elethan Dec 29 '15 at 22:06org-startup-with-latex-preview is a variable defined in org.el'. Its value is t Original value was nil Local in buffer prb.org; global value is the same– Andrés Sánchez Dec 29 '15 at 22:08emacs -Qversion 24.5.1, and orgmode 8.2.10. Only the buffer-local value oforg-startup-with-latex-previewis true. Try again withemacs -Q! This way your personal setup does not interfere. If this works your setup is the culprit. – Tobias Dec 30 '15 at 7:11.emacsfile into(when nil ...stuff...)and try your thing withemacs(none of the options-qnor-Q).
