shades/halos on display after home button replacement
I replaced correctly home button on Iphone 4 but the only problem is display because it has light shades/halo so what it means?
I used isopropyl alcohol but in other parts and I permitted they were dried.
What happened?
Update
I followed with great care all your steps as indicated in iPhone 4 Home Button Replacement to replace the home button in iPhone 4 and I think to have made no errors. I always sed surgical gloves.
This problem is not visible in white/black color background screen.
I used isopropyl alcohol in few dose by dropper for metal-to-metal parts (ground clips) and I dried immediately for 30-60 seconds blowing air from my mouth!
This smartphone is not mine so I’m not sure it the problem was just there.
I’m thinking where I made mistakes so I ask myself:
1- isopropyl alcohol??! Some drops reached front panel when I was assembling my iphone?
2- One month ago I applied 2 drops of isopropyl alcohol on home button and I continuously click it for 2-3 minutes, I remember Display had no problems. Then I left iPhone to owner and I don’t know if problem was
start afterwards. Yesterday I didn’t verify lcd before to replace home button!
3- During reassembly stage I left the clear plastic pull tab (used to lift the battery and you can see in step 6) under the logic board (you can see in step 19). When I noted it I remove only the 2.4 mm Phillips screw (that was hidden underneath the sticker in step 16) and I pull away and rip the clear plastic tab so I think few plastic piece is always below logic board. Can it this one the problem?
4- When I disassembly away the front panel from steel inner frame I layed the front panel (digitizer + LCD) on a cotton cloth, it’s this problem?
Do you think always is isopropyl alcohol?
