    Screen doesn't work, but phone makes sounds, how can I be sure it's an LCD issue?

    I really wanted this phone and found one broken on a local classifieds site. I checked the MEID number with Verizon and it's good, so I went ahead and traded some stuff for this phone. It came with the Dre beats earbuds, so worst case scenario, I've got a nice set of earbuds.

    Anyway, the guy told me the phone was in his pocket and he bumped into something and after that the LCD didn't show anything. I can charge the battery and turn the phone on, it makes sounds, and the orange light comes on but nothing appears on the screen. I can hook it to my computer and access the mem card, so it appears somewhat functional. The 16GB mem card he gave me isn't the original, so the filestructure isn't there. I told him I didn't want the phone without a mem card, so he got this one from his friend.

    I took the phone apart to verify connections and noticed that the screen backlight was working, I could see it lighting up from behind the screen with the phone apart. Someone had been in there before because there was a screw missing, but nothing looked water damaged or broken.

    Before I spend $30 on a screen, I want to ask a few questions. Could rooting this phone and overclocking it do this? Is there anything I should/can do to test the motherboard or anything else before I spend $ on the screen?

    I thought I had startup noises, but can't get those anymore??? With the phone still apart I verified with my multimeter that it's getting 4.31v and when the power button is pressed it drops to 4.28, yet the phone appears dead, no vibration from the motor, no sounds, nothing!

    When you guys turn your Rezound on, does the charge light also turn on and what color? Is that light only orange when charging and green when full charge, but not on at all when phone is turned on normally? I'm just looking for other ways to verify a dead LCD before I buy one.
