SOURCE: Black screen Sony Ericsson K850i


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: screen goes blank when being called or calling out!!!

A GREAT PHONE - spoiled for many by the screen blanking problem on making or attempting to receive calls. Some seem to have solved the problem by removing screen protectors, but this didn't work for me. I sent the first phone back for a replacement - but this was just as bad. The problem seems to be the result of a poorly calibrated proximity sensor - but you can re-calibrate it. The following procedure worked for me, but it's potentially dangerous, and could ruin your phone if you're not careful - YOU HAVE BEEN WARNED! 1. On the phone keypad enter the following code: 1809#*900# to bring up the engineering settings menu. 2. Scroll down to the entry called OTHERS and select it. 3. Scroll down this menu to the entry called PROXIMITY and select it. 4. You should see three options: Enable, Disable & Start Calibration 5. Select Start Calibration - after a few seconds it will return a new figure (mine was 3627) 6. BACK right out of the menu system, and make a test call - it should blank the screen when you hold it to your ear (or when you hold a finger near the sensor), but come back on again when you remove it. It worked for me - so now my Viewty Smart works just as it was supposed to. This information is offered without warranty - Good luck if you try it! 4 stars for the phone design - loses one for the delivery set-up, and lack of documentation of a fix.
This method worked for me.

SOURCE: my iphone screen goes blank during a conversation

If a hard reset (press menu and center button together for 5 sec) and software restore doesn't cure it , you have a broken proximity sensor or a broken logic board. There is an iphone repair website that shows you how to do the replacement yourself and a third party iphone repair company that can do it for you.

When someone calls me on my lg GC900f Viewty Smart the screen goes blank and i can't answer the phone The only button on the phone declines the call.. Can i change the button to answer the call? Or is...

Had the same issue.
It is the proximty sensor which needs
to be re-calibrated.
It was a little while ago now.
Can't remember the phone number you need
to call to re-calibrate.

Hope this helps.

Lg km900 blank screen during an incoming call -

There is a little rectangle shape thing next to the lg logo on the top of the fone screen. If this is blocked by screen protector it will cause the phone to blank of during calls. Its a power saver that blanks the phone when its near your face. Try it. Take off the screen protector & make a call. Then place your finger over the little thing & the screen goes blank. Just cut a lil space in the screen protector & that will fix the problem
