Question about Sony Ericsson K850i Mobile Phone

1 Answer

As I start to send a text message the backlight goes out on the screen and I can't see anything. It won't light up again until the key pad lights have gone. I'm not sure what the problem could be- I recently replaced the screen (lines were appearing on the old one) and it worked well for a few weeks, but now has gone wrong.)

GO TO SETTINGS AND CHOOSE ''FACTORY RESET'', AFTER RESETTING GO TO SOFTWARE UPDATE MENU AND UPDATE YOUR DEVICE'S SOFTWARE TO THE LAST VERSION, AFTER THAT IF PROBLEM NOT SOLVED MEANS THAN YOUR DEVICE'S GPU (GRAPHIC PROCESSOR UNIT ) IS DEAD, IN THAT CASE DON'T SPEND MORE MONEY TO CHANGING THE SCREEN AND GET A NEW DEVICE..

SOURCE: Black screen Sony Ericsson K850i

Hi,

I just had the same problem. I tried everything including resetting the whole phone upgrading the software etc etc.

I was convinced it was a softare problem, but my screen only went black when i press the buttons on one side of the keywpad so i started thinking it may simply be hardware related.

I tried taking off the case but didnt have the screw drivers to do this.

Eventually in a fit of rage I threw my phone on the floor (Carpetted floor) and too my surprise the problem got better! I basically gave my phone a few more whacks and it started to work fine again.

I am not suggsting you start whacking your phone, but i imagine if you took off the case and re-fitted it this would work.

Good luck.

SOURCE: My cellphone was good before.

The phone has hung up because there are errors in the software. So to reset remove the battery and the memory card from the phone. Using your PC , scan the memory card for any corrupt files or media files with virus- it is possible when they are downloaded from unsafe sites. If so remove or format the card. Now replace the card and battery and switch on the phone. If the phone hangs up then it is confirmed that the software is corrupt and will need a reinstallation. Seeking help from the authorized service /support centre is most ideal. Take estimate and decide.

Hi..i am using compaq presario cq 40 and screen is flickering.i had it checked and they told me lcd is the problem but they didnt even bother to check.they just turned it on and they told me that i have to...


When it flickers, can you still see the text when the screen goes dark?
May have to use a bright flashlight set right on the display to see
the text on the screen beside where the light sits.
That will tell you if it's the backlight.

You can also look at a grazing angle into one of the edges to see if the
backlight is flickering when the display does.
When it's cold, does it start with a slight pinkish color? That can be
a sign of backlight going bad.
Anything interesting happen when you flex the cable by moving the screen?

I'm not saying it's impossible, but I've never seen software cause
consistent screen flicker. And if the vga port doesn't flicker, sw is
even less likely the problem.

If you bet the odds, you'd bet on a bad display cable.
Won't hurt to try replugging it.

If that doesn't help, then your monitor may be dying....

I cant send text messages....... I have been sending messages untill 17sep..The moment I press [send] the screen goes black and re-switches on again.I can receive text messages. I can send picture messages...


Switch the phone off. Press and hold three keys together, the green key, the * key and the number '3'. While you are holding these keys, switch the phone on. Don't release these three keys before you see the Nokia logo. or dial *#7370# . This will delete the memory of your phone. Remove first your memory card.

The l226wtq goes black


Try shining a flashlight on the screen, or without the flashlight, try to see if you can distinguish anything on the screen at all, if you do, the backlight is dead, or the monitor has an internal most likely unfixable problem.

Sending text messages takes too long


out of curiosity,
what kind of sidekick was it?
and also, have you tried to give it a soft reset, yet? if not, then press it all keys down ( @ + 1 +0 ) without the + part.
and let me know its fixed.
if not, then you will have to force to do a master reset. (and yes, you will lose everything for a while. but, no worries, everything will come back in a fews as everything is in dangers backend sever as always, except, text parts)
here how: -press all the keys down at once ( @ 1 0) without quotes -when you see all 4 keys button come up on the screen, hold down the "R" and dont let it go until  you see the screen come on, let the "R" go and it will reboot once again. -and wait until everything come back and then try again to send yourself a text and see if its been sent sucessful.
good luck and let me know if works.
:]

My pantech duo phone doesnt work anymore!


From the way it sounds, mine started doing this yesterday. Everytime i turn on the phone, theres just a backlight and nothing else. well the only way i noticed to get it to work, atleast until i can get a new phone is, to leave it slid up because it wont do anything if its closed or slid sideways. And while it slid up, I either have to call it from my home phone or recieve a text message. I'm not sure why but that made the screen come on so I could atleast check everything. It doesnt always work but it does most of the time. I hope this helps. Just play with and figure out what it takes to get your screen on. I'm not sure how to permanently fix it though.
