[Q] No boot animation after changing display. - LG Optimus 2x

After i changed the digitizer and display the bootanimation doesn't show anymore.
I have to wait until startup has finished and press the power button a couple of times. Then it seems to work as it should.
Also if I boot into recovery it shows as it should.
Is the motherboard damaged, maybe the cheap display or is it maybe softwarerelated? I have tried several ROMs and the same thing always happen.

HELP! Phone boots but no responce after boot.

I am in the process of calibrating my battery. It was full and finally died after a good while. I put it on the charger and waited a couple minutes and tried to boot it up because I needed to make some calls and it goes thru the boot screens and animation and will dim but then it goes black. I press the menu button and end button to turn on the screen but it doesn't work. It will boot into recovery and the buttons work there. I have no idea whats wrong with the phone. Can anybody help me with this problem? Thanks in advance.
Edit: When I plug it in via usb the screen turns on but there is no touch response when I try to slide the unlock tab or sound tab.
I have no idea what caused it or fixed it. Randomly happened and randomly fixed itself.. everything is working fine now.

[HELP] Display glitches/black screen

Greetings,
I'm not experienced with android devices, so i thought i'd ask here first before trying to do anything.
Since a few months ago some weird things started happening to my X8 - random display glitches and blackouts at completely random intervals (sometimes one or even two a day, sometimes it can last two or more weeks w/o an incident, i haven't figured out any relation yet).
Glitches manifest in distorted view on screen - shifted up/down/sideways - or colored graphics artefacts - up to completely bizarre patterns of random-colored pixels covering the whole screen. Weirdly enough, pushing power button as if to lock the screen usually alleviates the issue, sometimes i need to do it few times to remove completely, but it works. Touchscreen works fine, but i need to tap the "right" spot on the screen, not where it's displayed on the screen ("right" as in where the element is when the screen is not glitching).
The other issue (may be related) i'm having with the phone is random screen "blackouts" - the screen goes completely black and the power button cycling doesn't help - but the phone still reacts to screen input (i.e. i can unlock the screen by dragging the slider, launch app, start/stop music playback and so on). I can see the backlight on, so it's definitely screen/gfx hardware issue, not backlight. If i try to reboot the phone, it hangs on either shutdown or boot up. Removing the battery, placing it back and booting the phone up doesn't help - it vibrates as usual, i see the backlight go up, but screen stays black and i can't interact with the phone even if i leave it there for a few minutes (which is more than enough for it to boot up - it usually takes ~30 seconds till full boot). Also the backlight won't go off. It usually helps to boot normally if i hit the phone with a palm on the back side and/or leave it alone for a while. This issue is much more rare (only had it three times), but it puts the phone out of service for a while, so it's an issue for me.
Now, the device info:
Sony Ericsson Xperia X8 E15i
015 baseband
10W44
Unlocked bootloader
Alfs8 kernel (2.6.29.6-Alfs v08a 24/03/2012)
GingerDX v026 ROM
No cpu tweaks done, cpu governor "ONDEMAND", cpu speeds 122-600.
The glitches started when i was still using the older version, GindgerDX v013 with locked bootloader, i have done factory reset and flashed a new version with new kernel (and unlocked the loader along the way), but apparently it did not help fix the issues.
I can't provide and screenshots/photos of the issue because the only camera i have access to at most times when it happens is my phone one and, obviously, i can't use that in this case
The question is: can i still try to fix it by myself (i can do it if it doesn't involve disassembling the phone completely - i don't have the screwdrivers required) by software tweaks or other techniques or should i reflash stock kernel/rom, apply for warranty and hope they find the defect and fix it? I really do like the phone. Or, maybe, you have encountered anything resembling these issues and may shed some light on what's happening.
Appreciate any input in trying to figure out and fix this.
Thank you if you have read all this even if you can't help me, cheers!
1st problem could be 'Screen Cut' issue which is solved using kernel without FPS Cap...
2nd problem usually happens on my phone with miniCM9 3.0.2 but shows splash and boot animation...
Can you see the splash screen and the bootanimation? Because my friends' Xperia Ray has the issue on official firmware... so it could be hardware damage...
Try unlocking the screen then press the power button then press it again...
and also try flashing the stock firmware... If it doesn't work... I think you should live with it...
Sounds like a hardware problem to me. Reflash stock kernel and ROM and full wipe and then flash a different ROM and see it it still happens. If it does I think it is advisable to send it to Sony for repair.

Thanks for your replies, i'll try reflashing the stock rom and see if it still happens.
@Lily48: no, no splashcreen or boot animation, just black screen and visible backlight.
I have the same problem and I checked it many times and my conclusion is....ITS A HARDWARE PROBLEM NOT SOFTWARE..

Well, notify me if you find a solution, thanks
Sorry for double post, but this is important update:
My phone died this morning with the permanent black screen syndrome. Until i rebooted i could use it to receive phone calls or even listen to music (i knew where to touch to activate the features). However it would not boot sompletely after restart, even if i leave it for ~hour. Connecting to flashtool showed that it does boot to a certain stage, but no GUI (for user interaction with haptic feedback) available - the flashtool does show that device connected with usb debugging enabled.
I reflashed the stock ROM, now it's apparently stuck in some sort of bootloop - it keeps on connecting and disconnecting. But the screen is still black, with backlight. If i remove the battery, replace it and just connect to pc w/o trying to boot on, it acts normally as if trying to charge - backlight activates for a few seconds if i touch a key and green led is lit, but still the screen is black.
I will RMA it tomorrow, thanks for help, hopefully i'll get a new one, or they'll repair this one so it does not glitch on me again. Anyway it was/is a good phone, i absolutely love it.
Wish me luck =]

It is a hardware problem and Sony Service Center is the last option you have.. if your X8 is in warranty period.
I did the same and they replaced its display with new one.
Hello, reporting back in:
Just got my X8 back, it really was a hardware problem. They changed the screen now it works as good as new =]
Thanks everyone for support

HELP! New Note 4 has black screen and won't display anything.

It boots up but nothing on the screen since I got it yesterday. Shows nothing when I plug in charger with phone off and doesn't show samsung logo whole booting up. Screen is completely black. The notification led, recent apps, and back button do light up and I am able to tap the screen and have it register but the screen just doesn't display anything.
Tried booting into fastboot and nothing, tried booting into download mode and nothing, tried removing battery and holding power for over a minute and nothing.
Help me before I have to return it. I g out. It for 380$ new from a recent cowboom.com deal and they're out of stock so they with be able to replace it.
One thing i did notice is that, even though it boots up and I can hear the water drop sound when pressing the back button, as soon as I hit the power button again, it reboots.
Maybe a fresh os install will help?
Return and get refund or send it to samsung repair center.
Looks like a digitizer problem.
I wouldn't send it to Samsung. I sent mine in and was returned in worst condition.

Looping between charging/Android logos

Hi, so I got an A2 which has been submerged in water for a while. I was not turning on at all (just showing the white led light blinking), so I bought a new USB part and battery for it, replaced it, and now it seems to react.
However, it keeps switching between the charging logo for a second, then vibrates and shows the Android One logo (this switch goes on and on forever). I have tried the button combo to go into recovery, but as soon as the Android recovery boot logo appears, it'll still timeout into the charging logo.
Does anyone know what may be going on? Or what component to replace? (the phone was only days old when it accidentally got soaked, so everything is new and it's a shame to just throw it away)

Screen stopped working randomly, now only notification light flashes.

Hello,
the other day I had my phone on the sofa next to me, working fine, I leave it there 30 min, pick it up, and the screen has all kinds of weird glitches. After a couple hours now the screen is completely blank and whenever I press the power button the notification light blinks a couple times. It's kinda weird tho because touch seems to be working (if I boot to recovery, then tap on the screen the phone vibrates just like TWRP buttons) and I can still boot to fastboot. Of course when I say boot it means that `fastboot devices` shows the device ready, but I can't actually see anything on the screen. I'll try flashing the latest MIUI now, does anyone know what this could be? I mostly just like to know whether I should try changing the screen only or if it's likely to be a bigger problem and I'd be better off replacing the phone entirely. Kinda sad, I loved this phone. Thanks.
