Few days ago i drop my phone and broke screen, i ordered a digitizer with lcd display, it has two connections to mother board, one for digitizer and one for lcd display,
after i installed new component i boot the phone, nothing appeared, lcd seems not working. Phone functions are all OK. I can hear unlock sound. Which means digitizer also work OK.
Then I tought new lcd panel is not working. Finally by coincidence I found that if I remove the battery and plug the charging cable, lcd screen magically starts working and it looks like this:

}
I tried to plug the battery when lcd is working. But again it stops working as soon as I plug the battery.
So are there anyone who have a clue? Why would lcd is not working with battery? I also tried with another lg g3 stock battery again not working. And if I unplug the battery and try to wireless charging still the same yellow triangle appears. Any help would be great! Thanks!
Today i findout, if i put some flashlight on screen in a dark room, i actually see phone screen is properly displaying. So lcd display is working but backlight not working when phone bootup.
It's confusing that phone backlight also works when battery unplugged. So any ideas?

Would you please let me know if you found a solution for this?
Thank you very much,

Hi everyone,
It is almost 2 weeks my XDA Orbit is not working properly. The first time it hanged-up during a call and afterwards it took me several resets to bring it back. During the system load the screen was changing colors and freezing, sometimes completely white, sometimes with some colorful stripes, sometimes solid violet. After several reboots I couldn't turn it on at all. I took it to local service, where they told me that the problem is with boot loader and fixed it. I took it back and have the same experience. I have flashed it with original ROM, both from PC or SD card, but the same problem exist. I am assuming that the issue is in a hardware defect. I know that it is the time to get rid of this PDA and get a new one.
Anyway... Is there a tool available for testing HTC hardware (CPU, flash)???

possibility the battery gone or the lcd.
buy a new battery, theyre only cheep so start there..
leave it off while charging, green led when done.
if its not your battery, i think its your lcd..
best to open the device and check your lcd is connected properly..

Opened my Orbit recently, the connector is in place. I would assume that the issue is more in battery then LCD. The battery surface is lofted.
Assuming that it's a battery issue - should the same happen if the device is always connected to external power supply?
...
LOL
get a new battery dude..
dont turn the device on untill the new battery is fully charged.
a simple fix hopefully..
Hi, I have a big problem with my desire!
I lent several months my old desire a family member .. It has not been very careful and had no protective case he does not like it .. The phone was still working when I was handed.. However, the fully plastic housing was very scratched and small pines broken.
So i order a housing from ebay. I followed this video on youtube to disassemble the phone : http://www.youtube.com/watch?v=sXZqIjtFoAU&feature=relmfu
I assembled the phone later and I have a problem with the screen. I tried several times to reset the screen .. the screen is beautiful no scratched.
Here is my picture:

Help??
The screen is broken, you need to replace it.
Dunno but i would take it apart again and just make its all put back together properly, u never know, u coulda missed something or something not connected right.

Hi,
I disassemble several times and everything seems normal. Except that the GPS connector is broken because its a very thin wire .. but I do not think it is connected!
The glass do not have to be broken, but as i said before this looks like faulty lcd or the connector. However i would say it's fault lcd, 'cos connector would rather give you a light gray screen.
Looks like it gets 'bloated'...
This is strange because the screen is in good condition and the connector too as everything is connected. So you think it is the lcd has a problem .. I disassemble again yesterday and no improvements. However, the volume buttons on the connector that is connected to a part of the motherboard's detached. Possible to fix?
Screen doesn't need to be broken to be fault.
If it was me - i would say the screen is broken and i would replace it as it looks so. But i can't promise that's it, sorry.
I'll wait in case , thanks for your time!
Hi Folks, looking for some help after I just about managed to replace a cracked screen & frame (I fell on top of my phone during a mountain bike descent into Glen Doll, Scotland as an aside!).
After painstakingly taking the cover, mid-frame, battery, motherboard etc out and putting them back together, I thought it was a minor miracle the phone worked again. The only issue I am having is that the screen switches off and stays off while making any calls, no matter whether I hold the phone to my ear or in front of my face.
Is this a proximity sensor issue? If so where exactly is it located and how can I check whether it's either damaged or not properly connected? Thanks in advance for any help
Sounds like it, Does you screen auto brightness work?
Its the little red sensor just under the top speaker on the right.
Nope, auto brightness isn't working either.
Do you know whether the sensor is soldered on or whether it can just be removed & replaced? The sensor seems to be in place but guessing it's not properly connected

I had the same problem as you and I think you also forgot to put the cover of proximity/light sensor.

Exactly the same problem on mine. Sadly threw away the part. Does anyone know the partnumber of this or where to buy it in Europe?
Hi,
In last weeks i found out, that my Note 8.0 has battery issues. Having 50% and making ex. Skype connection after 1 minute just shuted down. This was dead battery. I ran some test and i found that having 75% is dangerous. So i bought new battery and replace it. The new battery came charged to ~70%. I ran about 30 minutes. Second day i turned tablet on and started to working normaly , when suddenly screen started to flicker black to normal and repeated few times. After that screen gone black. I've connected charger to Note and all i could see was Battery image with blinking blue triangle [see img]. I've examined battery and found out, that one cord was broken. So i repaired it. Still no effect. Note works only with charger, without inserted battery. Sadly theres more. Last time i was working and suddenly tablet gone down. Without warning.
Anye ideas will be helpfull. I've searched for a solution, but i was fiding similar problems with overheating icon, but not with this blue one.

What happens if you put in your old battery? If the problem persists, I'm afraid the some circuit on the board has been damaged.

I'll try with the old baterry, but first i need to solder connection cables
I've done it. I plug the old battery back into tablet and i dont have problems with charging. It looks like the new battery is broken.
Yesterday randomly my Op3's touch screen stopped working.
From the last one year or so, there is a little gap between the mobile's display and the actual device because of the display glue coming off but nothing major happened with the phone in 1-2 days that can result in t's touch not working. I would have gone to the OnePlus service center but it is currently closed due to lockdown.
Does anyone have any idea if this means my display panel is dead or some display cable got loose which resulted in touch not working (or anything else)? I am attaching two pictures of the phone to show you guys about the display gap I am talking about.
Note: The display works perfectly and the phone works perfectly too if I connect it to my laptop and remote use it by USB debugging. Also, the touch screen problem is not caused by an app as the touch screen is also not working in the recovery mode (TWRP). Any help will be appreciated.

Screen and touch, display assembly is connected with only one cable on our device(navi buttons and fingerprint scanner are different). So if touch broken, probably it won't be able to repair. They will replace the entire screen.
Seems this thing happen to many people, i got it loosen in the same area as yours
They use double side tape which soften overtime+removing the phone from the case break it
Though my tc is fine because when i notice it i immediately glue it with standard tc glue instead using double side tape (much simpler, without opening the phone)
