After I have changed the broken display on DHD for the new set: Display + Digitizer, the new display doesn't work.
When I press start the vibro works only for seconds, and then I hear the system boot soud, but there aren't any information on the display, I can see only the backlight.
What is the problem?

I dont know too much about the hardware side of phones, but I know a lot about computers so I may be of some help lol
How many wires/contacts are there between the display and any external components such as the motherboard?
If only one, make sure it is plugged in correctly, the right way round, and plugged in all the way.
If there are more than one, make sure that if they have the same connector that you havent got them mixed up, such as the one that controls what displays and the one that supplies power.
This is all I can help with, sorry.
Thanks!
There is only one contact between the display and the motherboard.
I have connected the old broken display... got the same result - no info on the display. ((

Hello!
Everything is in the title!
I've dismantled my HTC Touch Pro II in order to change my broken LCD (but still functionning). I've changed the LCD panel AND the touchscreen stuck all together. But it seems not OK, as there's nothing on the screen, the touch panel doesn't respond. I know everything else is OK as I'm able to connect to my phone using MyMobiler...
First, I reassembled it, but the screens (LCD+touch panel) weren't responding, so I dismantled it again. Main board on my left, bezel+LCD+touch panel on my right...
Before assemblying it again, I'd like to know if the "rubber tape" with metal inside (used to fix flex cable ribbons) is absolutly needed for the screens to work or not?
I hope you'll have clues for me.
Hi
I had a wroking defy - I needed to change the screen because the old one had a row of dead pixels,
I've bought a new one connected it and --- I have a blank screen no motorola logo - no text displayed in bootloader - nothing can be seen also in recovery. The funny and sad thing is that now when I connect the old screen I have the same problem, eaven flashing a whole sfb does nothing.
Please help me see things ...
Unplug the display connector and replug it in, my defy's screen was flickering and i could not see anything but when i played around with that little connector, it fixed it.

just removing the lcd flex cable doesnt solve the problem..do the process in three steps
step1: remove battery pin(inbuilt battery) or remove battery..then press the power button for 5seconds..and then putin the battery..
step2:remove the lcd flex cable and the touch equiliser pin also..remove the battery pin(if inbuilt battery)..or simply remove battery..do every thing in the same process..dont jumble..after doing that..again press the power button for 5 seconds again..and putin the battery
step3:now assemble the entire mobile again with screws..because there are certain connections with motherboard and screen which will come in contact only after placing them tightly with screws
now poweron the mobile..this time it works..
the main reason is the failure of inductor component on the mother board(cant tell the accurate component name)..

Nope it doesn't worked..
100% my very same problem
I can confirm this problem was fixed by this

But for god's sake, be careful with tinning. A drop too much and you have a shortcut.
EDIT: intriguingly, I noticed I have another close up photo of basically the same area (please, don't bother with oxidation trails).

Hello,
my volume up button does not work, but i think i know what the Problem is. But i need help by identifying some components.
The board on the picture is not the broken board, but one from the same revision.
The red mark shows the position of the broken parts.
Thank you!
My phone also have this kind of problem, the volume-up button is hard to be push but there is no broken thing.
More pictures
I made one more Picture,
and i think that could be some kind of diodes...
Hello. This is my first thread, I have downloaded maybe hundreds of ROM's from this site, have read thousands of threads and of course bricked a few phones lmao. Now I am here with a REALLY confusing problem. Without further ado, let's dive in. sry for my bad english btw.
I bought a second hand S9 today. The guy whom I bought the device told me, when he turns off the screen of the device by pressing the power button, black and green lines appear when he turns on again, and after a few seconds, when he turns the screen back on by pressing the power button, the problem disappears he told. I think he said there is a problem in the part called screen flex. (I ain't sure what that is, I need info about that too.) Sorry if you're confused this far, cuz more is coming thru
I got a very useful APK file named "OLED/AMOLED Saver" and installed it on my device, it worked really well and the lines were almost invisible anymore. After a few hours of use, what I noticed was even more confusing. I activated the AoD (Always on Display) feature, coincidentally, while testing the screen, when I locked the device by pressing the power button and the clock appeared on the AoD screen, when I turned on the screen in that way, I noticed that the screen did not burn in as if it was brand damn new. But if I don't wait for the AoD screen to show up and immediately press the power button again, the screen turns on completely and something really, really terrible appears, a mixture of black and green. Now let's come to my questions, I've blown your mind a lot I think.
1- Can anyone explain what's going on here?
2- Is the problem in the screen flex or is it purely software? (AoD thing)
3-Is there anyone who has experienced this and was able to completely solve the problem?
Thank you for spending your precious time. Hope I get a solution..
Hello, I have same problem with my old S9, it seems that is fully hardware issue, as a workaround you can set full brightness - it causes this issue to appear less frequently and another option is cooling down the phone - when display is black/green just lock the screen and put your phone to the freezer for a while - it will work properly until it heats again
Its something about an update made by Samsung https://eu.community.samsung.com/t5...t-bars-black-screen-issue/td-p/1745470/page/4
