problem with replacing display on sony xperia z5 compact - Device Repair

The display on my Z5 Compact recently went haywire; it wasn't physically broken and the touch functionality still worked, but the display was unusable (colors out of whack, wavy patterns, zig-zags, etc.). I bought a replacement display, but after I installed it I can't get the device to come on. I can charge it and the red charging light comes on, but even after leaving it for a few hours I don't get anything. When it's charging, I do see something inside the phone light up bright white from time to time, but nothing on the display. If I let it charge and then try to power on the device, the screen will go from black to gray, but that's all I get. As far as I can tell I've got everything connected back properly, the only thing I'm not sure of is that part of the bridge over the ZIF connector for the display broke off; are there conductors in that? (I have a screenshot showing what I'm talking about, but I don't see a way to upload a local image.) The connector lock still seems to work fine. Any suggestions?

Xperia Screen Problem ??!!

Dear Friends:
I had today a very strange problem with my xperia. I did not drop it nor it was exposed to water.
when i turn on the device i get this white halo in the middle of the screen that goes to the corners of the screen. the screen looks washed out.
never had this problem before.
please advise.
Sincerely,
If you only see patches of light around the edges and in the middle on a black background, all it is is a bit of screen bleed, its normal and most x1s are like it. The reason is the X1 has a very strong backlight, if I turn my X1 up to full brightness it hurts my eyes and I find it difficult to look at, when your using the phone normally you dont see it, only when you turn it on, when there is no image.
Xperia screen display problem.

When i boot up the phone i thin lines on the screen.
Please advice if its a problem with the display or any other issue.
Cheers

I experienced exactly the same problem today.
When I connected the phone to my computer, the whole screen went white.
(This was the first time I connected the phone to this particular computer.)
Then I had an incoming call, i unplugged the USB-Cable (SE Original) and took the call - which lasted maybe 10-15 minutes - when I disconnected the call the phone returned to the default today-screen, but there was now a "halo", "ring" around the screen. (See attachment.)
Immediately performed a backup and Hard Reset, but the problem persisted.
So I thought it might be heat-related, so I let the phone be, and half-an-hour later the halo had vanished.
Specs:
Xperia X1i, Swedish.
ROM-version: 1.02.936.3
ROM-date: 08/29/08
Radio: 1.06.25.29
Computer:
MB: Gigabyte EP45-DS3
CPU: Q9450
OS: Windows 7 x64.
Google: Xperia screen white halo ring overheat
I turned my backlight to max and it did not at all look like that.
Send to repair..
Yeah, that's the thing, now it's back to normal I can't make it appear again, not by turning the backlight to max, not by plugging in the cable and taking a call like the last time.
Though I once had a TFT overheat on me, don't ask, I believe it looked similar.
That too returned to normal after about an hour.
So, I guess that's the solution - Don't panic, just wait a couple of minutes.
the ssame thing is happening to me. it gets worse when i receive a call and i would have to turn the screen off and on to return to normal

Something happened to my screen

Just yesterday I have noticed some weird line of broken pixels on my Sony Xperia z3 screen. Never put it under water or anything. Have always been charging with the dock. But last few times charged with usb connected to computer, so the flaps were open. I feel that somehow the liquid or something penetrated under the screen. The line of bricken pixels can only be seen against black background. See the pic of display service test with black background.
Is there any way to fix it? What can I do?

Nexus 5 Display not working. Don't know what to replace.

So, I was trying to replace my Nexus 5s camera and I disassembled the main motherboard. Replaced my camera and everything but after I reassembled the phone, I found out that there's no display. The LEDs work fine, because I see them light up and I see that the screen is black but it's a bright black and the screen is on. So after tampering with it, I found that the little USB charger port wire board wire thst connects just above the battery (idk how to describe it, its the orange strip that locks the battery in place) had a direct correlation with the display. If I unplugged it, the screen would go dark and off. If I replugged it, it would be on again. After doing this a few times, I actually got my phone's display to show for a little while before it went away to black again. So will buying a new orange strip part work or would I have to go to the bottom where the little screen digitizer is? I'm sorry if the problem is unclear because I really don't know how to say it or explain any better. Please help.

Replaced display and now get LED status blue blinking, sometimes solid yellow etc.

Hey there hobbyists and experts.
Recently I wanted to play around with my old phone. The Sony Xperia Z1 C6903. Rooted it, flashed a custom ROM on it, and so on. I noticed a spot on the display that didn't register my touch inputs so I decided to replace the display, digitizer and the frame. After reassembling it, and plugging it into the powersource, it didn't explode :good:.
But it didn't display anything on the screen. I only noticed the status LED.
- Sometimes it flashed blue. (Not Fastboot)
- After leaving if plugged in for a while, it turned solid yellow.
- When I tried to turn it on again, the LED flashed red and then afterwards purple.
Does anyone of you have an idea on what the problem might be? Or any clue on the LED signals?
Should I disassemble again, and check every wire?
Thanks in advance.

black screen after falling down

Hi,
My Pixel 4a5g fell on a carpet. No external damage is visible, but the screen still does not turn on. Also no LED when charging.
I have read a few times that this is a known problem and that the display is broken internally. I would order a new display from iFixit and change it if I knew for sure it was because of this.
Is there any way I can test if the phone itself still works, but just the display doesn't show anything? Would it give any sign when connected to the computer?
Translated with DeepL
It could be a loose connector(s).
Could be the mobo, battery and/or display was damaged. Inspect and go from there.
Always use a good case to protect the phone for high G loads from drops.
