Possibly broken digitizer? (clicks are mirrored) - Sony Xperia M

Hello, so...
I got this phone and because of broken screen Ive changed the glass part with digitizer. Now the digitizer is acting... weird. Like the screen is divided horizontaly and the upper part is changed with the bottom one and its also mirrored. When I pres down left corner, the dot of touch appears at the top right etc. Is this because I somehow f**ked up the flex cabels or can this be recalebrated? Ive tried to disassemble and connect it again and also resetting the phone to default and then flashing whole rom again but nothing helped. Any ideas?

Are LCD and touchscreen functionning while phone is dismantled???

Hello!
Everything is in the title!
I've dismantled my HTC Touch Pro II in order to change my broken LCD (but still functionning). I've changed the LCD panel AND the touchscreen stuck all together. But it seems not OK, as there's nothing on the screen, the touch panel doesn't respond. I know everything else is OK as I'm able to connect to my phone using MyMobiler...
First, I reassembled it, but the screens (LCD+touch panel) weren't responding, so I dismantled it again. Main board on my left, bezel+LCD+touch panel on my right...
Before assemblying it again, I'd like to know if the "rubber tape" with metal inside (used to fix flex cable ribbons) is absolutly needed for the screens to work or not?
I hope you'll have clues for me.

[Q] Dodgy touch buttons

Im having some trouble with my physical touch buttons. They seem to stop working every now and then. If I bash the phone on my hand a few times they usually start working again. I'm guessing theres a dodgy connection inside somewhere thats causing this. There are no other symptoms though so it's very specific to the touch buttons.
I've opened the phone to have a look if anything looked loose but on the face of it everything seemed fine. However, I wasn't sure which ribbon was for what and couldnt find a diagram anywhere on the net after a quick search. Can anyone help identify what all the connections are for? In the picture I have circled the 5 main connections. So far I have figured the following:
Black circle - touch for screen
yellow circle - metal docking contacts on back of phone
red circle - not sure possibly speaker/touch buttons?
blue circle - not sure possibly speaker/touch button?
green circle - vibration motor?
If you know better please correct me. I think the touch buttons either work off the screen touch responsive connection (black circle) or the red or blue circles but cant quite figure out which.
Thanks
i know the gold colored part on the bottom left of the phone is the digitizer connector, is the rest of the screen working? if not make sure the aforementioned connector is pressed down securely

Everything else is working fine, no issues with screen whatsoever, its just the touch buttons. Thats why im trying to figure which connector does the touch buttons

[Q] Lower part of screen not working

My touch screen works fine except for the lower part of the screen. The portion that is not registering is the part where the quick launch icons are as well as the "back" and "options" button on the bottom. This started happening after a little rain got on it. I took it apart and tried cleaning all of the connections with isopropyl but I am still having this issue. Are there any connectors or anything else I should look for to help resolve this?
Thank you!

When i press the bottom left side of the phone or just touch screen near the return button , strange things happen to touchscreen, it starts to click all over the left side of screen, i tried to look at the screen connectors but they look fine.

Screen Flickers

Hi Guys,
Everytime I press the top part of my screen (front cam, ear piece part) the screen flickers and sometimes it shows a horizontal line anywhere on the screen and it only happens when i press the top part screen.
I ran a LCD test using #*808# and the screen is fine. It's just happens when pressing the top part of the screen. Even when I'm in the recovery mode and pressing the top part of the screen it still shows lines and flickers.
You guys think it's a hardware problem already that something might be loose connection on the motherboard?
Tia guys!
