I have replaced the screen on my HTC radar. I bought the LCD and digitizer assembly. Since then the proximity sensor won't work. When I make a call the screen goes black. I have found that putting some pressure around that area (top left corner) brings it back but as soon as I let go it stops working again. I did not use new adhesive when putting the screen back and there is some light leakage between the digitizer glass and plastic frame it fits into. I have darkened it out with electrical tape but still no joy. Any ideas. Do you think cutting the small plastic cap that covers the proximity sensor would help?

i have replaced my LCD screen and digitizer but when i put the phone back together the LCD does not light up but the digitizer worked i know this because i tryd turning the phone off by holding the pwer button and sliding my finger down on the digitizer and it worked. so i am puzzled this is the second screen we have tryd now im convinced its software or another part of the phone like the motherboard. any ideas please please let me know as i have everything on this phone dating back since the release of the handset.... thanks
