samsung m3200 screen problem

[farryabadi]

hi everyone! this phone belongs to a customer, as he says he has droped the phone 4-5 days ago and initially the colours on the screen were a bit funny but after a day or so it goes back to normal and phone has been working fine till today that after answering a phone call and haniging up the screen goes off. i was wondering in your opinion flashing would bring the screen back or the damage is physical? and if flashing helps should it be just tfs flash or bin+tfs flash?
i would ever so grateful if you reply to me with your advice!!
many thanks.

ps: ns pro doesn't read the phone info for this model so i couldn't post any log!!
