I've got an iPhone 6 with a backlight that occasionally dims for no reason in the top left corner.

A phone repair shop tried attaching a different screen for a minute to diagnose the problem and the problem seemed to go away, however they wanted to charge me $120 for the new screen.
Can someone suggest a cheaper way to go about this repair? I'm in Melbourne.
The phone works great otherwise.
Thanks.
Buy one off ebay and replace it yourself
Otherwise go to an apple store and get them to fix it (unless youve previously repaired it by a kiosk), it will be a similar cost to one of those kiosk places and you will get a warranty on the fix.
