Hi everyone,
I might have broken the screen on my HTC magic (sapphire) but i'm not completely sure. The screen does not show any signs of cracking, however shows a static screen of red green and blue horizontal lines (ill provide a picture). It is clear the phone still boots as it responds to touch (the vibrator goes off when I tap what would normally be my lock screen). Interestingly, the phone battery drains almost instantly (within 30 seconds) from a full charge and the processor gets warm, however, if I disconnect the screen it will remain on for a normal amount of time (vibrates, so I know it actually turned on, but no red light indicates battery is low).
So can anyone provide a diagnosis and possibly how I might be able to fix it? I appreciate any help.
Thank you.
I am not sure about your symptom. However, I found my htc magic had a vertical line last year but display ,multitouch, everything work fine. Luckily, it was in warranty, after I sent to the htc service center, they replaced my screen and the problem gone.
Thanks for the reply, did your screen look like the photo I provided of mine?, or was it just a single line through? I had a look on ebay, screens are only about $30 and by the look of things, not too hard to fit. However I am a bit hesitant as I cant be sure that the screen is the problem, because there's no signs of cracking, its just perfectly straight red green and blue bars vertically down the screen, which seems to me (i am far from an expert) like the screen isn't broken, the signal going to the screen is, also and it seems weird that the screen would cause the processor to heat up so much and drain the battery so fast. Anyone else with any ideas?

Hey all,
I was turning my screen off last night before heading to bed when I noticed that I could still see the picture frame widget while I was stood under my bedroom light....it looked like it had burnt onto the screen as you could only see it faintly while direct light. I then turned it on and off again and the picture frame widget disappeared but area in the top right hand corner of the screen could now be visable again under direct light. I flicked the phone on and off again a couple more times and eventually it was completely blank.....anyone else experienced this? Is my handset faulty or is this just a characteristic of mini TFT screen? I know it hasn't actually burnt the image on the screen as I don't leave the screen on long enough for it to occur and its not just residual light as it doesn't fade, but it will go completely blank after a couple more on and off's.
Strange one,I will try and reproduce it when it is dark tonight
Sent from my Dell Streak using XDA App
wiki term called "Image persistence"
might help u
Aaahhhh...thanks dead101, so just a characteristic of LCD screens....had me worried for a bit!
haven't checked out that terminology yet, but i am pretty sure that LCDs do not have the burn in effect in the way that the old CRTs did.
I've noticed this phenomenon as well, and haven't noticed it on any other device. It always goes away if I press on and off again. I don't know that it is image persistence, because that seems to require leaving it off for a period of several hours to remove the effect, not switching it back on and off quickly.
I'm worried it may actually be a fault where the screen sometimes won't switch off completely. One night, my Streak went from full charge to dead in about 8 hours while on aeroplane mode. Could be unrelated, or could be that the screen was still drawing a current. Who knows... it never happened again. Annoyingly I could not get the "what's been using my battery."
Either way, whenever I notice that part of the screen is still visible after putting it on standby, I always switch on and off to clear it.
Hi,
Since few days I am facing a unique problem with my Note 3 N9005 phone. The screen background show a very light but permanent Charging Icon (Flash icon) and it is visible in all apps with white or whitish background. The more strange thing is that when I tried to take a screenshot and attach it here, the screenshot did not contained the charging icon which is permanently there all the time.
Can anyone please help how to get rid of this annoying flash/charging icon?

Read and learn about the strengths and weaknesses of AMOLED screens.
The main plus: AMOLED screens don't need a backlight like LCD screens because each individual pixel lights up; in result, if a pixel has to show completely black color, it's practically turned off, hence the reason black wallpapers are recommended for AMOLED screens.
The main minus: AMOLED pixel may start to die. Almost literally. What you are describing sounds to me like what we call "burn in" - when a certain part of the screen shows the same image for prolonged periods of time - like the Charging icon. This icon has probably stayed in one place for years, being lit only with white, and consequently it's easier to notice against a pure white background.
tldr: your screen is slowly dying, not much you can do about it, live with it, or have the screen changed. Or get a new phone.

Thank you very much for describing the possible root cause and how AMOLED screens work. Actually, m y phone has an issue and it doesn't recharge when it is ON. I have to OFF my phone and plug the charger and then it starts charging in a different way i.e. the Charging image (Battery picture with a flash inside) appears for a little while and disappear. This process keeps repeating
until I unplug the charger. I hv been charging my phone like this for more than 6 months. Does this give a clue that if I repair the charging IC and recharge my phone properly and the flash icon gets away within some time?
Must be a common issue with this model. I have the same exact model with the same exact problem. Only the icon though. My charging works as expected. Charges any time I plug it in.
My S4 keeps rebooting and I think it's a hardware issue but I do not know exactly which part might be the problem. It did slip out of my hand and dropped on my desk (not that hard) but it did not show these symptoms until a few days later so I'm not exactly sure if the drop is the cause of this issue.
It does not necessarily reboot at the Samsung boot screen all the time. It sometimes reboots at the Samsung logo screen or after 1-2 mins at the home screen. It has also frozen at the Download mode screen, so I don't think it's an OS issue or a bad app.
I've already tried a different battery (new one I just bought recently) and I don't think it's a Power button issue because as I initially thought it could be problem with the Power button so I had removed it and had planned to solder a new one. Without a power button, it still freezes/reboots. I did notice sometimes after it has frozen, when I try to charge it nothing happens (no red light) but once I pull the battery out and put it back in, it charges again. Also sometimes when it freezes, I have lines on the screen, but once I take out the battery and restart, it's ok.
I would hazard a guess that the LCD or digitizer might be the problem (but I don't to waste the money if it ends not being that)? The only reason why I say this, is because I managed to get to the home screen and enabled USB mode (screen was off after) and it did not reboot or freeze for more than 5 minutes (longest so far) until turned on the screen and seconds later it rebooted.
Can anyone advise whether it is likely the LCD that is the problem? I plan to get a new phone soon but wouldn't mind fixing this if the parts are fairly cheap.
Any help would be greatly appreciated!
Answer me this: If your computer freezes, would you suspect the screen? I mean, the screen's sole purpose is to display stuff. So why would the screen cause the computer to freeze?
Same story, different device.
Your issue will most probably require a motherboard replacement, as I don't think you can find the faulty parts separately. I suspect either CPU or GPU.
Hey Guys,
My release edition S7 Edge started acting up last Sunday. As I was using the phone, it noticed the display to have strange, colored barcodes appearing as smudges on the screen. Pink/purple seems to be the dominant color type and they are most severe when texts are displayed on screen. The phone seems to get hot quicker than normal, and gets hotter than normal when under toll. The screen usually DOES NOT TURN ON AT ALL when the phone is warm/hot. Everything about the phone still works, all functions work.
It has been a few days since I encountered this issue and it has not subsided. What I did noticed is that if the phone was hot and the screen does not turn on, I could cool down the phone externally via air conditioning vents and it would turn back on when its cool enough. The barcode artifacts are also less prevalent, to non-existent when the phone is cold to touch.
I initially thought this to be an display panel issue that needs replacing. Out of warranty repairs is going to be about CAD $340. With the cooling down work around, I am hoping it may be a less expensive to fix issue.
What do you guys think? Help me out!
TL;DR. Phone started having pink and purple barcodes all of a sudden. Works perfectly with the barcode. Display wont turn on when warm/hot. Everything is back to normal if the phone is cool/cold to touch, until it starts warming up due to usage.
Unfortunately my 5 month old phone dropped into water and stopped working :crying:. After much research, I have successfully opened up the phone following this excellent demo without causing any damage to the screen and body.
As shown in the pictures below there are rust near the connection slot between screen and the mother board. Actually that is the only place I've notice any visual anomaly. After thoroughly dissemble everything from the mother board and clear all the rust with 99% alcohol then putting them back together, I'm still stuck on the following status:
- When disconnected from wall charger, and long press the power button, the LED lights had a very brief green flash, then went dark. After that when I touch the finger reader in the back, the machine vibrate as if it is trying to read the finger print, but the screen stay black (dead).
- When connected with the wall charger, the LED first show flashing red light for about one minute, then stay solid red for another few minutes, then turn off. Again, the finger print reader is responsive to touch, but the screen still stay dead.
- Finally, when connected with the 360 camera, the camera lights up and the internal fan also spin up, making me believe that the phone battery could be functional.
I tried pressing down power + volume down/up buttons simultaneously for 30 seconds to enter the bootloader, but the symptom stay the same, the screen remains dead.
I've also purchased a brand new screen replacement from a reliable vendor and tested it on the phone, still the same symptom. So I assume it is not the screen issue.
At this point, I would appreciate any help in:
1. Diagnostic. What does the 1-flash green light, flashing red light and solid red light means? Does the fact that finger print reader vibrate upon touch tell anything about what's working and what's not?
2. Other way to check the battery?
3. If I want to purchase a motherboard, given that I'm on AT&T, does the replacement need to come from another AT&T phone? I found one on Ebay where the seller mentioned the IMEI is clear but carrier is unverified. How does the comparability work?
Thank you for your help!
Hi! I would like to help you with this problem. First we would need a better picture of the motherboard, where the damage as been created. (Screen port)
Second, you could always give a call to Essential, I think they offer a replacement for 200$? Still cheaper than a new phone and don't worry about purchasing a phone that doesn't come from AT&T, I have the Telus model and it's the same as every other essential phone on the market.
