Question [Q] Black screen but still has sound and still usable ?

Hello All

I have a HTC one X. I installed Cyanogenmod on it a few days ago and it was running pretty fine. Until last night my phone started to freeze a few times. So I reflashed the rom ect and it fixed it.

This morning I was messing around on this phone and it froze yet again so I held down the power button to reboot the phone.

Now the phone itself turns on but its shows a black screen. I can unlock, I can hear sounds, I can even receive phone calls and text messages and play around on the phone (but cant see anything)

I have tried plugging it in to my pc and going in to the SD card but in order to do that on cyanogenmod I will have to tun usb storage on, on the phone which i cant seem to do.

I am wondering whats going on with my phone and are there any ways to fix it or is this the end of it ?

Regards

Gentle
