1 open a picture
2 zoom on the picture, you may navigate the zoom
3 test your EVF sensor whether is it working
4 delete your photo(while in zoom factor)
WHILE activate the Live>EVF sensor
SIMULTANEOUSLY>>>NEED PRACTICE/REPEATING
5 Hang...
Pull your battery out to reset
Step 4 requires practice or repeatation
NOTE:
Tested with other machine(a55/a33) beside this and all have the similar problem, Tried Using different Mem. card and battery, with or without lens...
Do not blame me if you can't work out with the situation as i teach the SONY technician and demonstrate with him for whole day for him to work the problem(cause the problem) to occur...and they tested with all other machine which show the same sign
don't ask me why i do this sequence because normally i'll use EVF for all purposes including deleting/viewing bla bla bla...so in reality, when i delete a photo(after zoom) which coincidentally similar with the 'steps' above the problem occurs...
Comments welcomed..

test it and follow u step yup is got this happen.
