Doesn't that also means that if the green line is caused by the mainboard, I would have wasted $54 since I need to pay the amount upfront if I sent in for repair? Not a lot. Just wanted to know the pros and cons.
		
		
	 
I was given the same warning at the plaza sing service centre.. and they were able to assess on the spot if it's mother board or screen... don't need to incur the $54 upfront.
Not sure if it is case by case.
But u have to backup your phone as they will do full factory reset at the counter before sending in for repair.
I suggest u go to the plaza sing service centre to talk to them. They have dealt with hundreds such cases. Make appt first before going down. The waiting time will be reduced significantly.
At the end of the day, it's a still big hassle. I ended up buying a new phone to back up the phone first before sending in for repair.. now the repaired phone is my spare phone
