Hy
I try to replace a broken screen by a new one but, i have a white screen, i chek all and i can't find the pb.
I tried also to replace with the bad who have just some picsel defect, but is blank too?
Do U think I crash my Kaiser?
or I forgot something?
I just installed my new LCD & the same happened. I took it apart again & noticed that the ribbon cable that connects the bottom buttons to the top LEDs was torn. It sucks! Now I have to find a cheap replacement. :-(
yah Im in the same boat....white screen...the phone works fine....what ribbon does one need? is it just the flex cable ribbon attached to the lcd or is it this thing (link)
Hey
A friend of mine called me yesterday if I wanna buy his broken X1 (it felt down :/) and repair it, because I'm the man for such jobs
Do you think it's only the LCD-flex-cable or another repairable damage?
I think I can get that device for 2-3 days and then decide if I buy it...
Some ideas? Is there any chance to repair it?
Thanx, Carbon
yes, probably even a loose connector on flex cable
Hello,
I am quite certain it is an easy problem, i have seen many x1 phones with just a minor loose connector which causes the screen not to respond.
The best way to check it if it really is just the screen/flex cable is to turn it on, and check if the side lights flash in all colors.
If that works the phone should work normally. (even if the screen doesn't work)
After opening:
Re-insert all the cables in the screen flex cable and check if it works..
if that doesn't work then replace the flex cable.
If the screen works:
Then check out the screen if it has any crack's or black spots.
In that case you will have to replace the screen/touch screen also.
Generally, if there is no physical damage to the LCD itself and the phone buzzes on startup with all appropriate sounds - replace the flex. Flashing lights are attached to the flex and are positioned ABOVE the LCD on flex connection, therefore will not light up if the flex is damaged and neither will the upper keypad and other less obvious things.
The flex replacement is not minor, just be aware of that. Bad falls are also the reason for main PCB damage, in which case there will be nothing you can do.
Thank you so much
It was a "very short" call by this friend, but when i take the device, I want a precise report what happened...
atm I don't now if the sidelights show reaction, but I will report
I'm afraid of a real PCB damage...
In flex problem side lights will not light up, as i mentioned, they are positioned above the Lcd connection, so if the main flex connection ribbon is damaged, as is most often the case, all of the upper level functions will be gone, but you will get a startup with buzz and sounds present.
I got it
And LEDs are flashing and you can start it complete normally, but you see nothing... i'm going to open it and check the Flexcable

Best of luck.
So I just changed the LCD in my phone because the previous one broke (my fault..I was soldering in a new charging port and broke the ribbon cable for the LCD by accident). I turn on my phone and there is no red at all. The X was all funky and mostly blue with some hint of green. :/ Is there a calibration or reset I have to do when changing the screen? Everything is connected properly. I've triple checked the connections.
Good Day to All,
I have a problem with my Z3+ E6553, the problem is that there is no display on the phone. Couple of weeks ago the lcd just stopped working, the device does come on with the LED lights, vibration and the touch is reponsive with which you can here the touch sounds, haptic feedback and the Speech to text speaking. I thought the LCD screen went dead and so I bought a new LCD screen to replace it but after replacing the screen the problem still presist with no display(black screen). So currently I have no idea what is the cause or what to do next.
I opended the phone was just check some things out, and I had a look at the LCD flex cable and I found something strange that maybe one of the connector antenna prongs missing. But I'm not sure if thats just how it is or its maybe it got damaged. Have a look at the attached pictures below.
Can someone tell me if this issue is with the LCD motherboard flex cable, or another hardware issue maybe being the motherbaord?
Hello guys, Yesterday i changed the battery on my phone. After putting everything back together my screen stopped working, with no image and no touch function. The cable on the right bottom is connected but perhaps i damaged it in some way..
The phone is working properly, if I connect it to an HDMI it works.
Any ideas on what I may have done wrong and the solution?
I took it to a shoo and they say I have to replace the whole screen (USD 100 approx) which seems too much..
Check this coil. If it's shorted it's ok, if not make jumper on it. Also check filter (small bricks) under the LCD flex connector and LCD flex itself if it's not teared. Those are common damages which can be done disassembling this phone.
Yup it's the LCD flex that is dammaged.. Is it possible to repair? I'm guessing that on a shop they will want to change the whole LCD screen..
Unfortunately there is no way to change flex only. If it's damaged You have to change whole screen.
Ok, oh well that's life... thanks for the help though!
