Boot up / splash screen issue

Hay everybody...
I have a slight problem with the splash screen (am refering to the green color "WINDOWS MOBILE 6.1" Screen) of my diamond.. though the problem is very minute, it is driving me nuts !!..
After i started cooking and flashing new roms onto my device.. The splash screen does not show up correctly.. What i mean sometimes the top bar (which has the start menu, the network bar indicator, etc) shows up along with the splash screen.. and sometimes the keyboard shows up along with the splash screen.. Though after the device has fully booted up and the home screen shows up, everything is perfectly normal... Its just that when splash screen shows up, it looks very ugly.. So I wanted to get rid of this... Could anybody please help !!!??
This is very common and happens somtimes to me - I dont see it as an issue - Just annoying. I changed the screen to something with a black back ground s0 it does not look that bad any more.
Oh !!
Okhay.. So its a common thing.. Thanks for the info.. In that case could you post your splash screen, i too wanna get rid of this annoying issue... ;-)

Strange problems

My phone LCD backlight went out but other than that worked fine. After installing a new screen the phone will not boot past the moto logo.
I can get into recovery and charge only but if I try to boot normally it goes blank after the moto logo not even showing the boot animation.
Reinstalling old LCD allows it to boot but with no backlight is unusable.
Anyone have any ideas?

Assuming you are 100% sure you've hooked everything up correctly, it sounds to me like a faulty/incorrect screen. I've read about this happening to other people (Bionics, though), luckily (so far) I've never had any issue with any screen replacements.
I'll check the connections again. The replacement screen came from a damaged Droid 4 that would not even show the moto logo.
I was lazy and rather than open it all the way and replace only the screen I swopped the whole upper part of the phone slide. I'll try doing it the right way.
Edit: checked all connections and tried again. Still no go.
Where is my torx 3 bit!
Edit 2: tried again. Still works with old screen switching only the screen (and the things that CAN NOT be separated from it) still won't boot. looks like I need a new screen.
Did you buy a broken D4 and try to swap the screen? If so, that unfortunately might be why it was broken in the first place... The plus is that might then be an easy fix too... Then you'd have two!

I did get a broken D4. It had a bad board and would not even show the moto logo.
What's really strange is yesterday it was still not working and today it booted fine but now the touch screen is not working.
I'll keep trying to fix it.
Honestly it sounds to me like the front portion is busted. Perhaps it is just the digitizer that is broken, those tend to be much cheaper than LCDs...
Good luck and let us know how it pans out, it is always good to hear solutions to hardware problems!
Both touch screens/digitizers work with the lcd that has a bad backlight but not the one with the good backlight.
I examined the LCD with the good backlight and found a very small tear in the ribbon. Looks like I found the problem.

[HELP] Black screen on new phone screen

Hi, my screen broke recently and i can't use the tactil touch. I can see the image but can't use. So i decided to buy a LCD + Tactil Touch + Frame. I didn't mount yet the screen. I only disconneted the screen flex and connected the flex of the new screen. But the problem is that is black. The screen seems to turn on but i don't see anything, is all black.
EDIT: I don't know where to ask. I flashed to the stock ROM, 4.2.2 and still black. I updated to the last version Sony has for my phone, 5.1.1 and still is black. I don't know what more to do. Is all working good, even the sounds when i touch the screen. But i can't see anything the screen is working but there's no image. My phone is Xperia Z.
Anyone?
Please help!
Broken screen? Is the old one still working? If yes: return the new and broken display and get a replacement!
The touch("screen") and feedback (vibrate and sound) will work without the lcd! It is a different layer on the screen and is seperatly connected to the mainboard of the cellphone. Also your screen could be working and your backlight not! Turn on the phone and point a bright flashlight on the screen, maybe you will see something, but even then, get a replacement.

Screen Black and White.

I bought a screen of eBay which said it was OEM but who knows? Anyway I had the screen installed at a phone repair shop and it seemed to work fine until I walked out of the store and turned it on to notice that the screen was black and white. I turned it on and off again and it went back to normal but i went in to tell them anyway when i was walking in I turned the screen in and off a couple times to see if I could get it to go black and white again and sure enough if did. It seems to turn black and white every couple times I turn it on and off. It doesn't flicker back and forth and it doesn't charge when I'm using the phone also i had a custom ROM installed so I got rid of that to see if it would fix it it didn't and I reset the entire device to no avail but I did notice that to this point I haven't had it go black and white while in the boot-loader and i have tried a lot turning it on and off again and again. I also noticed that there are lines bouncing in the background when the screen is black and white which are also visible when the screen is normal but only barely. Apart from that the screen seems to shake when its in black and white and sometimes the touch wont work for a couple seconds its not a big deal because you can just turn the screen on and off to fix it but its a very strange problem i have contacted the seller and I talked to the man who installed it but I was wondering if it was possible that it was some kind of software issue it seems unlikely but the fact that it doesn't flicker on and off its just either on or off and the fact that i cant seem to get it to happen in the boot-loader is making me wonder I also tried recording my screen and the screen was recorded normally when it was black and white to me.

I need help with screen

I just bought a replacement screen for my mi 8 but it has no display. I believe the screen is working because there is a display when booting (I can see splash screen) but after the splash screen the screen goes dark again. the fastboot also visible. do I need certain firmware for this screen?
update:
I have made it work but with only miui 10 8.6.18. if I try to update 1 version higher the screen goes black again.. does anyone know what the culprit could be?
