Problem with screen after Xperia Z repair.

Question

Hi friends,
I have the following problem. I have Sony Xperia Z (c6603) which I purchase on 07.2013. Two months ago the phone broke in my pocket (Display, touch screen also the back panel - all gorila glass parts ). Because there is no official service in my town(Plovdiv, Bulgaria) I give the phone to some service here and they changed the broken parts. Now phone have some other problem: After few (2-3) hours work screen begin to flickr, letters look like they are swimming in water and later part of display turn to black. I am big fan of Sony and have lot of their products (Phones, TVs, Cameras) but I am really in love with this phone and I wonder is there some way to fix this problem or I will have to continue to use Mine Xperia X10. May be later in 2015 will change it with Xperia Z3 but now I dont have this opportunity. Here some images before the reapar:

Hi guys, Well your problem lies in not reusing all the foils and flex covers from the original display, flex cables are close together and are creating an interference. When changing display make sure you do the following: 1. Turn off the phone. VERY IMPORTANT, you can damage the battery by just unplugging it while phone turned on (also LCD). (Hard turn off is with power button + volume up.2. When disassembling make sure to remember where all the covering foils from flex cables go, do not bend flex cable too much, use common sense and light touch.3. Do not start the phone before you have all the screws in and DO NOT TIGHTEN TOO MUCH, also back cover should be in place, notice two golden dots on the back plate especially on Sony Xperia series4. When backlight flickering (strobe like effect) on sides occur even after following steps above, DO NOT PANIC!, turn on a game or any application that won't turn off the display for a few hours, plug the charger in and burn the LEDs on the backlight, as time passes you will see the flickering disappearing slowly, mine was about 2-3 hours5. Turn off the phone to cool down.6. Voila  Mine worked this way and just because I panicked I torn away the mic flex and all that was needed was a little bit of patience. Hope this helps someone.  btw, the pictures above, that is either interference or damaged flex cable, but I believe you just need to put the foils between the flex cables.Hi I will like to try out what you are saying but would be better if you uploaded a photo or youtube video link or explain better what you mean by the foils. I ordered my xz 6603 from singapore and 3 weeks later after I did and OTA  I had similar problem, I called the supplyer and sent it back for repair I was told it wasnt a hardware problem but that I had installed an incompartible OS version (weird since I did an OTA) but it took 6 months to get my device back, I got it back in Feburary and now thesame problem has occured as i have upgraded to lollipop. I cant wait another 6 months to get the device back again
