If your Sony Xperia Z3 smartphone shows no image but the backlight is working, there may be a problem with the phone’s logic board. This problem can occur because of failed screen replacement attempts. Use this guide to repair your device.
Alternatively, see this Sony Xperia Z3 no image after screen replacement YouTube video for help micro-soldering the logic board.

Sony Z3 no image after screen replacement only backlight Hardware Repair
-
-
Heat the back cover of your Xperia Z3 to loosen the adhesive underneath.
-
Lift up the back cover with a suction handle and put an opening pick in the gap.
-
Move the pick carefully around the edges to loosen the adhesive on every side of the phone.
-
-
-
When the edges of the cover are free from adhesive, tilt it to allow access to the battery tabs.
-
Use tweezers to pull the two black adhesive strips out of the phone but don't pull just yet.
Careful during this bit. My old Z3 back cover couldn’t take it and split into lots of pieces (probably weakened over the years!). Just order a replacement for £3 off ebay before doing it ;-)
Merci pour ce tuto. Excellente procédure. Travaux réalisés en 20 minutes sans aucun problème. Attention: au remontage, il n'y a plus d'adhésif sur la batterie, la coque arrière peut éventuellement tomber. Je ne l'ai pas fait mais il faut peut-être mettre un petit double face sur la batterie.

Unplug the battery flex connector.

Use a tweezer to gently pull off the adhesive strip on the bottom part of the battery.

-
Use your fingers or the flat end of a spudger to unclip the cables holding the logic board in place.

I have a z3 single, it turns on the backlight but not the image what to do? procedure above did not work …
i &&^&@@ my display
How hot (how many C) should the iOpener be? I think it would be safer / more accurate to heat the iOpener in an oven with accurate temperature control.

Careful here. The back cover cracked in two places. Once when I exerted pressure with the suction handle, and in the corner when moving the pick around the edges- even though I was very gentle. The battery was adhered firmly to the back cover.

I cracked the back cover instantly. Make sure to buy a spare one before opening!
