Screen goes black (no backlight) when making/receiving a call
Need some help here. I replaced the broken digitizer on my fiance's HTC Radar. Got everything back together and the phone works perfectly until you try to make/receive a call. Any time a call is made/received, the screen goes black (no backlight or anything) until the call is ended, then everything comes back. I've tested everything else and it is fully functional besides this. Anyone else ever have this happen or have any suggestions on how to trouble shoot it? Thanks!
Is this a good question?
