if the wireless transmitter is still working and also the focus assist beam still comes on, then perhaps it's just a cosmetic defect, shouldnt be a big prob... send it in to respective svc ctr to repair loh...
i bought oone yongguo 460 II from ebay. sometime in feb this year.it was working fine
3 weeks back, as i was careless, aand drop the flash light from table to floor.the defect is my red plastic cover broken. it was still working fine.
i mount it on lightstand. working fine
last week. as i mount it on dslr. the relase got stuck on hot shoe.
no happen how i use brtual force. i am unable to release the yn460 off.
in the end. i took small screw driver to dismanlte the flashlight.
the lock spring stubborn stay there.. well i still have no gut to mount back on hot shoe..
it still work well on optical trigger. but the sensor i am unable to mount properly
rule of the game. always be careful with ur gears. if fall . check it well.
