hi Eric,
are you sure it's not 28tn525s.
this model is the new 2020 28 inch version but there doesn't appear to be a
28tn5255.
and what is more confusing is that the 28tn525s does have audio description but
doesn't have the talking function according to it's manual.
i have got the manual for the 28tn525s if this is the correct model which i can
send to you.
please let me know.
pete.
