Q: 

1. In salaah I was reading a surah after surah fatiha. As I was reading it I wasn't sure if I read my surah fatiha, so I started from the beginning with surah fatiha. Is my salaah accepted?
2. In the future if I forget if I read surah fatiha what should I do? Should I make sujdah sahu , or as above?

Q: There are 2 silence boards in the masjid, but the one in the masjid has a white background and the head and hand are black color. Sometimes when I join the saff this board falls in front of me, or to my left or right, or sometimes diagonal (2 o'clock). Would in such instance my salaah with this board makruh? I have told the chairman about this board and he told me since the head has no eyes there is nothing wrong with it. Is this true? Since I have told them and they say there is nothing wrong with it, and if it is in reality indeed makruh is it still makruh for me since I have approached them about?
