I dropped my phone and the screen now doesnt respond properly: The hardware DID successfully upgrade to the XDA ROM. But touching it causes the backlight to go on, - but most of the keys dont do what one would expect them to do: The phone turns on with a reminder from the calendar on the screen which wont DISMISS or CLOSE. Pressing on the windows logo and then on the phone key causes the calendar to come up and I am not sure which numbers are entered when I do manage to get the phone to come onto the screen (none of the right hand numbers seem to work at all). Does anyone recognise these symptoms and/or could they just show that my SX-56 needs the ROM RE-flashing? I should add that pressing the Master Reset button with this ROM in place seems to make the phone shut off and then when you restart it, all of the data remains in place. I wonder if there is any possibility that the XDA ROM has prevented the reset button from working normally?

A user on another forum said that to him, '"Sounds like the digitiser is up the swanee - have you tried recalibrating it?"

10-12 vertical black lines started appearing to the right hand edge of the screen. Sometimes they are there, sometimes not. THere is usually at last one there somewhere. At about that time the screen stopped responding as I mention. Today the left third started displaying the same veritcal lines, though spaced quite far apart (about a millimetre). Screen doesn't APPEAR cracked: Does this sound like a digitiser and if so, how do you recalibrate it please or is there a link to somewhere on the XDA site which I cant find which might tell me? Or could it be the cable is loose in the circuit board? As you touch the lower right hand corner of the metal casing where the vertical lines are, those lines flash (the right 10 or 12) on and off. And every coloured bar everywhere on the screen or word of text has vertical lines on it (the white parts don't)??

Someone on ebay has said that his phone "fell from my pocket and onto the carpet and the screen cracked, I then used it for about a week" "I sold the screen to someone cause the wanted the touch pad part of the screen for there phone". and wonder what it was he sold or which part can be replaced on it? IS there a touch part and a screen part on this phone?

To be honest, itsounds like you have brocken a connection somewhere between the LCD and the gfx output, probably not possible to repair yourself.

I thought that might be the case: I wonder if it would be worthwhile trying to get another screen?

I should probably try to take the unit apart and see if some break somewhere can be identified if it is a break as opposed to some electonic part having failed. It SEEMS to be in the lower right hand corner?
