[Q] Screen only works when hot - Galaxy S II Q&A, Help & Troubleshooting

Hi All,
Hope someone can help me, my screen only works after its been heated on radiator for 2mins. Hope someone has a suggestion. Any help be great.
Thanks

This listen like a hardware defect.
If u have warranty any longer, use it.
If not u can ask on a phone repair station if they could have a look on it (ask before if the first look on it also costs or not)
Sorry for no better solution.

Software or hardware related???

hi guys, like a week ago i lost my g1 and now im looking for a replacement... im not a noob so please dont talk to me like one
the history goes likes this, a friend of mine has a samsung vibrant and it has this glitch, the lights of the bottom buttons go on and off constantly and the phone vibrates like when someone is calling you... my question is, can it be fixed by flashing a new rom or can it be hardware related??
I have not been able to try the phone, i just saw the problem via webcam so i dont know exactly what sets the lights up or if its a random thing....
any ideas?? i want to buy the phone but i want to know if i can fix it with a rom or not
Why doesn't your friend get a warranty replacement first before you buy it second hand?

maybe he stole it from someone haha xD i dont know.... i think he bought without contract but he doesnt have a warranty and he wants the money asap....
please answer my question guys
edit: we are not like close friends, I barely know the guy... just so you know...
If it was a software issue we would all have the problem. Do not buy it.
Check the LDI under that battery, it should be white. What you are describing sounds a lot like liquid damage.

Touchscreen no more working after de-assemblage and re-assemblage

Hello xda guys!
Like a dumb i decided to change the front cover of my sony x10 mini, so, i decided to open it and de-assembly my phone.
It was all so easy, in few time and simply i got all the parts of my phone not mounted.
So i began to re-assembly every pieces and all looks fine, but, when i turned on my phone, after all the boot image i saw the sliding unlock command was not working good
The touch-sensor was not sensing my touch properly.
So i decided to de-assembly it again e re-assembly.
After this the phone was no more sensible at touch!!!!!
What did i brake?
What did i damaged?
Thanks for helps in advance.
Hi, As I saw on this video (http://www.youtube.com/watch?v=OpCb0oxd_3c), there are lots of wires in this device.
Didn't you forgot to plug in one of them ? Or did you damage any integrated circuits ? Must be one of these if it's a hardware problem. It can be a firmware problem too but it's kinda obvious it isn't seeing the facts.
Anyway, i guess you should go back to SE's 2.1 rom and send it back to the customer service, i fear that it would be even more damaging to open it back again :s

My phone is this.
Well, now, my phone is definitely a test one (warranty no more valid), so i can do tests.
I guess i damaged the circuit or the sensor abled to sense touch, just because, all the other function looks working good.
I'm not sure on a thing: should i resolve just changing the motherboard or the display?
Ah yes, I misread you're on mini, not mini pro. Well, displays are solid componants. Unless the ribbon cable is damaged. I see no point in changing it. It's easier to damage a motherboard.(did that on my pc...)
These videos are awesome but i'll never try that myself. Too afraid of loosing my phone !
Yes! This should be the way! Thanks for the precious hints!
Definitely resolved!!!
Just changed the frontal cover!!
Now my phone works like a new one!!!!
I just checked out the official SONY ERICSSON X10 MINI repair manual on a wiki homepage. If someone need the link just ask me through a email!

Should it be "assembly"?

[Q] hard brick i9300

hi,
my i9300 seem to be hard brick, but i don't understand why and how because i strictly did nothing
my phone is not rooted. it was in my pocket, and perfectly working, a few minutes later i would use it and it died.
i thought it was the battery, so i tried a few things that i could find. but nothing works.
all i tried did nothing (the screen is always black)
the big problem is i'm living in montreal canada and the phone come from miami so samsung want repair it :crying:
help me please
I'm sorry to hear this, but looks like you are one of the many with sudden dead gs3.
If you cannot fix it at samsung. Best chance would be to buy a motherboard or a smashed gs3 and use the motherboard.
I think would be cheaper to send it to samsung and let them replace the board for you. Email them and ask and compare prices.

My girlfriend Galaxy s2 is having a lot of problems

Hey Guys,
My girlfriend is having alot of problems with her phone lately.
It was turned off occusionaly during the day.
I've replaced the rom on her device and though it would fix it.
I bought the akku polarcell 1800mah for her because I had good experience
on the past with polarcell battery for my previous galaxy s1.
Guys I don't really know what to do and my girlfriend is counting on me to fix this ..
I told her to put some papar near the battery to have it better grip with the electricity circuit.
Maybe there is a Corrosion- how to fix this?
Guys,
Please let me know your input on this and how to solve this.
Looking forward for any input- thanks in advance.
All the best!
thanks you guys
Be nice and get her a new phone. Keep the S2 for your ownself. Problem solved!
You can't really fix corrosion, because it tends to spread slowly throughout the device over time. It depends on what's damaged, if you're lucky it might only be the USB board which is cheap to replace, if it's components on the motherboard then replacing that is more expensive, if it's through the whole phone it might even be a bin job because it's probably going to continue to get worse over time.
Only way to know for sure is to take it to someone qualified (I.E a mobile repair shop) & have them take a look.
Edit - Or...You could replace the USB board yourself & see how that goes. It's easy/quick/cheap (~US$10) to do yourself, search for KeithRoss39's guide in General (search for 'replacing USB charger board' or similar), and if you're lucky this solves the problem. If it doesn't, then you take it someone qualified for diagnosis (and in changing the USB board, as you're pulling the phone apart, you'll be able to see if/how much corrosion is there).
Thanks for the quick replies.
The issue is we don't want to invest money in this and would rather staying with the phone as it is if needed.
How can I make it better?
Any Idea?
Did you even read my post ?
You can't. It's obviously something hardware-wise going on. You can either take that advice & possibly fix the phone, or put up with it in its current state. There isn't anything 'easy' you can do.

What rom did you put on it?
Aosp or sammy-based?? The reboots can be software related

It's a very custome israeli rom
called yoelz-rom

Sooo... I soaked my Honor 7.

Hi!
To make a long story short, I got my phone nice and wet. After that the only thing that would work is the charging light and "utility" button(flashlight). I disassembled the thing and it had some oxidization goin on. I cleaned as best as I could....Assembled it back and it pretty much does the same thing. Only charges, flashlight works and it doesn't give me haptic feedback but I can browse the phones data storage on my pc...
The reason I'm posting is that do you guys have any insight/experience on similar stuff... I'm somewhat sure its the screen module(digitizer) that doesn't work?
Also, if you have bought those cheap ~30-40€ unbranded replacement modules...are they any good?
You might want to bring it to service center now if oxidation happens. I have a few experience with getting phones wet, but just wet and not soaked like yours. I just let them dry and they are working again.
