Congratulations for the forum!

Maybe someone can help me with the following:
My phone main key as stopped to work meaning that I am not able to light back the touch screen as well as access to the menu allowing me to make call. But, the phone is not dead because if I plug usb power cable, display light on and I can use the touch screen with the pen making use of the phone as normal. But... if I stay more then 5 second without action on the display, display will switch off and I will not be able to switch on and use the screen to operate the phone. Definitely I though it was my key that broken! I opened the phone and took out the key by de-soldering the flat contacts. I have checked with a multimeter the key itself and it was ok but on the phone pcb (where the key was solder) I found continuity between the 2 points (I think that only when the key was pressed I should have continuity!) Any suggestion to find the problem?

Thank in advance
