Hello,
I have an S620 running WM6.1. Everything has worked well for ages, but for no apparent reason today the screen "crashed" and is 90% white noise (like a TV with the antenna cable pulled out).
I tried a cold boot which seemed to work, but when I then shutdown and put the SIM back in and re-started - no dice. Back to WHite noise. I have subsequently tried a few more cold boots but all I get now is the top 10 % of the screen shows the green windows startup logo all squashed up.
The wierd thing is the phone itself appears to still work - but the screen is useless.
Can anyone offer any help ?
thanks
ur screen seems to be cracked.. u need to replace a new one
You can easily get a cheap on off ebay and then there is a youtube video that demonstrates to you how to install a new screen. Its fairly simple and cheap.
but if ur gettin the dream jus wait and dnt wrry
ok, thanks for this guys. Its a bit strange that its a cracked screen as I haven't dropped the phone and it looks in perfect condition from the outside. I did wonder if perhaps the internal ribbon cable might have fractured somehow or become loose.
I will crack the phone open and have a fiddle !
If anyone else has any thoughts I#d much appreciate it.
The phone isn't worth much but I really like it. I even handed back a Nokia E90 communicator (which I personally think is crap) to my company because I prefer the 620 with WM6.1.
Hallo to all!
i've already tryied to search this topic in all the forum, but didn't find anything...pls tell me if something similar already exists!
so my problem: i have a touch pro 2 (RHOD100), and the last week i broke the touch screen (due to accidental heavy pression on it)...all works, but no TS function...
so (here starts my trouble) i decide to change by myself...i bought a new one (only TS) on ebay and make the change....
no problem with the hardware change, but now my display stay white...
some consideration:
- OS start with no problem (start sound and button sound)
- all flats are plugged correctly (checked many times)
- the backlight of the lcd works well (low light after some time)
some help? maybe i forget something important?
thanks a lot in advance to any helpers!!

When you changed the touch screen did you remove the flex cable that connects the upper half of the phone to the motherboard? Are you sure you didn't break the LCD screen itself?
hallo,
yes i remove the flat, and plug back again where changed - when i press on the TS (with white screen) i can ear the "tap"
i cannot be sure, but it light on...i think is enought...or not?
thanks for you're help!

It looks like like either the flex cable got damaged or it's not plugged right. It could also be the LCD flex, where lcd plugs into the small connectors under the four buttons at the bottom of the touch screen not being connected properly. Did you lift the small levers where the flex cables go into the mother board or where the lcd/touch screen gets plugged in or did you just push them in?
i lift the lever where pull out the flex, and pull it down when restore the connection... and i'm almost sure about connection, also because them are so "stricted" in the plug himself...
but i find really strange that the lcd is on (completely white), you don't think so?
also if it is damaged, should be not white...or maybe, as you say, a flat problem?
this evening i will re-open it for a check...i don't know what else do...
maybe i will try to buy a complete kit (TS+lcd)...
i will surely let you know

The screen being white, means it's receiving power but not video signal. There coud be different reasons for that. It happened to me couple of times. What I did was lift the connector lever, pull the flex connector out (where it connects to the motherboard) just a tiny bit and secure the connector with the lever and it worked. If the flex cable is going bad it could be that just one line or two are going bad not the whole thing, thus still delivering power but not video signal.
If your problem is with the flex buying a new screen/digitizer will not fix it. When you screen is white does it go out if you slide out the keyboard?
hallo,
sorry for late answer,
i make some test with flat, but the result is the same...
the screen always stay white, but i can ear the start sound, the pression sound, etc...so it seems it's just the lcd...
maybe i can try to buy a complete set lcd+ts?
thanks for answer

I could be wrong, but I think it's the flex cable that is bad not the LCD screen itself. The flex cable has several small thin lines, what is happening is the power is getting to the LCD screen but the video signal is not, so most probably one of teh video signal lines is broken.
Hey guys, I cracked the screen on my HOX so I replaced the screen with a unit from directfix.com
After double checking all of the flex cables I tried to power the phone on and I am getting nothing from the screen and the vibration motor is constantly buzzing.
The only signs of life is the red LED, the three capacative buttons will light up, and the aforementioned constant vibrating. If i hold the power button to attempt to turn it off the buttons blink several times then it seems to stay on after that.
Has anyone heard of a problem like this before? Its killing me not having my HOX! I had to put my sim card in my old iphone 3gs and I have to say that this sucks really bad.
Are you sure you've connected everything correctly? It sounds like there's something being shorted! I'd recommend you to dissassembly again, an assembly again BUT THIS TIME VERY CAREFUL. Best is if you use a video tutorial if you think you're not experienced enough.

Thank you for the advice. I disassembled the phone and carefully put it back together. I took care to make sure the flex cables for the LCD, vibrator/button strip, antenna, volume buttons and digitizer were all carefully connected.
Now the vibrate function seems to work fine as it just gives me a short pulse when I turn the phone on as it usually does. The screen however, still refuses to turn on. I made extra sure that its flex cable was put in the right way and that it was secured with the jaw bone connector.
This video here www youtube com/watch?v=OIeO0DueMcg&feature=youtu.be at about 6:00 shows that you can test the LCD midway through the assembly process.
I tried exactly that and the LCD would still not turn on. I am just hesitant to return it because I know that the chances of the screen being a complete dud are very slim.
Now when the phone is turned on the three capacitive buttons remain on which I know didn't used to happen.

Update: So I was thinking the phone was booting up all the way, but I just saw that my computer won't recognize the phone beyond making a connection sound; I just can't see it in windows. As i said the capacitive lights stay on, but if I fold the power button they blink 15 times exactly and the phone seems to power off. Should I assume the SoC is dead or gamble with a replacement LCD?

Hi, I'm in the exact same situation you have described above! Did you ever manage to work it out, what was the solution? Any info or help at all would be great, thanks!!
I did replace my lcd+digitizer as well as yous. And I had same problem. But it does work now.
1.open up your phone . Take all parts off, separated.
2. Take battery off.
3.Now connect power button.
4. Connect battery.
5.Switch it on (hold pwbt for 2sec), mobo+battery+power button itself.
6.Now wait 20 sec.
7.Now connect LCD ribbon(bottom one),make sure it's right in, push it in far as you can.
8.Now put it righ on bezel and connect digitizer ribbon.
9.Press pwbt and see does it work. If does put rest of stuff together and be happy.
I can make phototutorial on request.
I did it few times. The battery was touching the LCD ribbon and it comes of very little but screen comes off and I have to start all over again.
So make sure that ribbon it's not getting any pressure from battery.
Let me know does that help.
Sent from my repaired HTC One X
Hey guys,
I think I destroyed my HTC One X. I just bought it a month ago from Ebay, and it worked flawless. At some point the display just turn off. I restarted the phone, heard the sound when it starts and even the softkeys worked. But the Display was still off. After after a few restarts the display turned on for a minute, just to freeze after that and turned off again. The phone was still on though.
However I've read a bit around and found out that it could be a cpu heat problem, which could be true because my phone was way too warm sometimes. So I removed the display and put a tiny little bit thermal compound on the cpu. Somehow I managed to rip off the connection cable to the display ... also I managed to rip off the little black cable near the soft keys. The soft keys still work though.
When I start the phone the starting sound comes, the softkeys blink when I restart the phone, you hear the volume buttons etc. So it seems the phone is fully working. Just the display or touchscreen is damaged.
Some pictures:

So, what can I do?
Do you think I could just send it to this site http://www.directfix.com/product/REP-0063.html and let them repair it? Or did I destroyed my phone too much already?
Thanks in advance.
Well,the top cable is ripped off,you can't do anything at this point.The bottom one just seems out of slot as far as i can tell from the pics.
Basicaly you can send it to the repair shop,but i don't think that you can only change the cables,don't really know what to say...Could cost you some to repair it.
I don't want to only change the cables. I want to use this full repair service:
"HTC One X Complete Screen Replacement Service (Includes LCD & Digitizer)".
So they change the cables and put on a new LCD & Digitizer as far I understand.
But do you guys think they will put back the other cable back in slot too?
Please just answer, do you guys think they can repair it if they put on a new screen & digitalizer?
I don't see why not,you can also contact them and explain them the situation.Those cables are quite easy to put back with the proper tools so you don't have to worry about it.
Hi there.
My First Gen Huawei Watch suddenly turned off its display today and even though it's off I can still feel the usual haptic feedback of the unlock code and the do not disturb modes when I click around on the dark display.
Everything seems to be running normally apart from the screen which only is displaying black and won't turn on.
I have tried long pressing for a forced restart and can feel the usual vibration when it restarts. No Huawei logo or Wear OS logo is visible either.
I have let the watch drain and when connected to charger the screen is still off.
Randomly a few hours later the screen came on again only to go off after a few minutes again.
Any suggestions?
Thanks!
I had this same problem - it was due to water getting into the watch and causing corrosion between the touchscreen connector and the metal back of the watch. Ultimately in my case the battery was bulging and forced a gap between the frame and the back. If you're handy, watch some videos for opening the HW1 up. It's honestly very simple to do - but note that the screws on the back of the watch are Torx T2 NOT the T3 which some online guides say. Get some high % IPA and Q-tips and clean the connector a bit. I repositioned the insulator pads to cover the corrosion part and watch worked good as new.
