try installing my mobiler and see if the display shows up correctly on screen on your pc. It won't help with your phone but it will let you know if it is hardware related on your phone. If the disply does not show up correctly on your pc screen then I doubt its the display chipset on your phone that is bad bc it uses the cpu on the phone to display your screen on the computer. If it does show up corretly then it is more then likely a fried video chip on your phone and should be able to get a replacement for free as it is hardware related.

Steps to getting it fixed. Did you get the phone wet or do anything that would break the display? Thats what they are going to ask you. Have you had the phone for more then one year? as thats the ammount of time that is covered by the factory hardware warrenty from HTC. If both of those are no then flash back to stock and relock it b4 taking it in to get a replacement. You shouldn't have to claim insurance bc of it being a hardware error.

1 more thing does the screen show anything on it when booting or does it always show black even while booting?
