[SOLVED] Screen problem - any ideas? -> SOLVED, LCD BROKE, REVERTED TO ORYGINAL

Hi,
My phone just froze today during making a call.
After taking the batery off and turning phone on screen look like on the photo.
Phone works (I can hear for example volume change), but screen doesn't change.
Any ideas? Phone didn't fall or didn't have any contact with water - I was just trying to make a call.
Is it a hardware issue? Does anyone know the cause?

Hey.
It seems like a hardware problem.
Anyway, get it to bootloader & connect it to the PC, try to confirm fastboot access & flash the RUU using this guide http://tinyurl.com/RUUGuide
If it is software related, that should solve it.

It is hardware-related. Problably LCD issue.
Anyway - I flashed the oryginal rom and everything is the same, so now I restored CID and locked bootloader and I will try to send it for warranty repair.
Thanks.

how did you solved the problem , because i have the same issu and my screen look like your's ?

[Q] No signal after screen replacement: Damaged motherboard?

I was doing a screen replacement on a Nexus 5 and a small part from the motherboard fell off.
3 pictures to illustrate the problem here:
http://min.us/mKOC4FQe6F0HI
Afterwards, the mobile connection was a lot worse than before. Now, 2 weeks later, the phone's connection has become unusable and it constantly shows no service. Only very rarely does it have any sort of connection (Edge/3G/H/4G).
Questions:
1)What is the part that came off? (see album above) My knowledge is a bit limited but I'm quite sure it has to do with the connection? I notice there are 3 other parts exactly like this spread over the motherboard.
2)Can I repair it? Do I glue it back on? Do I solder it on? Does it somehow click on? (I have tried if it clicks but this part is so tiny it's almost impossible to really handle
3)Based on my explanation, do you think this tiny part is the only cause? The phone still had some connection at first but it got worse. I'm also planning to order replacement antenna cables to see if that helps.
Thanks in advance!

In my case.. I had to replace the charging circuit Cuz it was 'broken' as described by the cellphone shop.. It has connections to the antenna.. Now phone is fully working.. Before that though, I tried different sim cards with different companies (bell Rogers and fido) all worked on my phone except my carrier sim card (mobilicity). After replacing the circuit I just mentioned everything works fine. Cost is 25$

Needs solder it's an rf trimmer /radio frequency. It's vital to an ariel of one type or other. If you want to risk a bodge assemble everything except the back and hold it in place with bluetack. If it works I was going to say epoxy it but don't. Get someone to solder it. It's easy to do if you have the skills.
Oh vital it's right way round and has now been turned. There should be a slot for tuning it.

[Q] Graphic problems with p5100 10.1"

Hi,
I got this weird problem and im not sure is this a hardware problem or not. For example. when using menus with white background, the background goes partly blue. Sometimes the graphic error is only blue lines in some part of the white background.
but when checking one option in same menu the background turns normal or atleast there is some change in the background. So these errors reacts only when changing options. And theyre always in the same position when going the same menu.
Also when using camera. the view is messed up a bit. there is a clear line somewhere in the picture when going dark to bright. With my english its hard to explain especially when i dont have any idea what is causing this problem.
Below are two attachments that explains the problem much clearer than i can write:

}
And before you ask. Yes, it has dropped and i have replaced the glass. But i got it with broken glass so i dont know was it like this before it dropped and the previus owner couldnt tell either.
Any possible solutions?
Thank you in advance!

Sounds like a hardware issue, just for the heck of it I would open it up and check the ribbon cable to the digitizer/screen, it could be loose.
Pp.

Checked it. Same problem. Tried to change brightness level, hard reset, rooting etc with no luck.
Its just so weird that in some situations the screen looks totally normal. only these few situations cause errors in the screen.

Hmmm, there are dialer codes that are used on phones that run a series of tests to check screen performance and output, don't know if this can be done on a tablet, but I would research it.
The only other time I heard of this was on a phone that recovered from falling in a toilet, the phone was dismantled and cleaned and assembled and it worked fine for over a year, the only glitch was an occasional color spasm on the screen similar to what you discribe.
Pp.

Thanks for the tip! Need to look for those codes when i get back home. I removed the logic board and cleaned it with denat. alcohol. No visible damage at least! trying to assembly it back later today. I decided to order a new LCD flex cable. Its the cheapest part to change.

No luck with the codes i found. after cleaning still same graphical problems. Now i can only wait the new flex cable and hope it will fix those errors.
Anyways thanks for replys and suggestions. :good:

Power Switch Repair [If Things went very wrong][solder-pads-wrecked] [Hardware-Hack]

Hi I just wanted to completely brag
Ok I bought a N5 on Ebay with a "broken" PS-(Power-Switch).
I have seen a few way to repair it and thought this could be really doable...
It wasn't what I would name a "good hit" ^^
The phone had already been opened and a very unsuccessful repair had been conducted.

Ok as you see, damn ^^
SO the solder pads were toasted (only epoxy)
Impossible to get it to work.
I googled (a lot) and found this thread from Rizwan Sayyed
http://www.mobilerdx.com/2015/03/repair-lg-nexus-5-d820-power-button-ways.html
Well, I did it The wire used is 0,35mm winding wire (they are isolated)
I actually have brought a litlle mods on it.
Here a pic:
why is it awesome? ^^ Well, because there is actually only one MB hack, which reduce of 50% the possibility of failure
The left port of the switch has to be connected to the little resistor as explained by Rizwan Sayyed
As soon as the frame of teh switch was still linked to the ground. I just had to solder the right port to the frame of the switch.
IT IZ DONE
That's actually quite simple even if VERY VERY tiny. It took me age to get it correctly welded and I must admit that I thought a bunch of times that it was "dead"
I secured the wire with hot glue (be careful it's tricky)
NOW there is a little draw back to this mod. The aluminum main back cover has a support directly on the ground trace. As soon as you have your hack-wire on the trace. You will have to substantially remove material on the rear cover.
Like this:
THAT'S ALL FOLKS!
Hope it helps some desperate guy somewhere
## Please note that this hack is actually pretty advanced and require MAD SOLDERING SKILLZ. Do it ONLY if you know what you are doing and are LIKE ME very very very good at it ^^## <-- Yes me pretty (and) proud
The Grüß,
H.
PS: Image are huge. "open in a new tab"

Please advice
Hello doodjob, thank you for posting this amazing info. One of the contact points (the one shown here i.e. the one you have connected with wire) is broken on my PCB, while the other is intact. Can you please suggest what I can do? Any suggestion would be greatly appreciated. Thank you!

No signal/ No service little Solutions

Hello, I would like to present my solution to the no service problem.
Some two weeks ago "no service"show on my phone, I tried many ways to solve the problem:
-I tried different sim cards
-I changed my ROM with LGUP
-I make ROOT on the phone
-I change modem file
-I change modem options i Hidden menu
Nothing helped !!!But today I restored the phone(H990DS) to life and I would like to share my solution.
First of all, the symptoms my phone has had:
-No service
-signal strength 0dbm 99asu
-inpossible RAT in hidden menu and network mode
-impossible to change BAND in hidden menu
My solution
In my case, the problem turned out to be hardware, although I thought it was a software
First, we take out both covers with antennas . We unscrew four screws from each cover and pull them by pulling or slightly undermining.

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
at this point, when I switched on the phone without covers / antennas, this one tried to go to the network and I could choose RAT and mobile network.
Tthere was a lot of dust and other **** under the covers!
I cleaned everything nicely with a brush. Then I cleaned all the marked pins on the phone and in the covers with alcohol.
Using a small flat screwdriver, I slightly raised the pins on the motherboard for a better contact.
Later I turned everything back and my phone is working properly
I think that the muck caused resistance and the modem turns off the transmitter so as not to damage it. I hope my solution will help someone, sorry for my English.

Same Problem
I've the same exact problem with the same model. The pictures in your post are not visible. May you please, re-upload the pictures or send them by email?
My phone is a brick

I found a few old photos on google drive.
After pulling the battery cover, you can see 8 screws from the plastic covers / antennas. You unscrew the screws and pull the covers until they come off. You can undermine them, it's easier to go down but there is a risk of damaging something. I do not have v20 anymore, in my case the way I described helped about 2 months. After this period the problem occurred again and helped replacing the motherboard ordered in China (the new motherboard had a problem with the zyroskop ). I hope you will have more luck, it was a very good phone if it was not for defects.
