Hi,

My HOX touchscreen was broken, the touch and everything was still working. I ordered a replacement lcd display Unit and replaced the complete display and touch. After replacement the screen is completely black but the phone still works. The touch buttons on the bottom still work and i can use the volume buttons. I replaced the lcd display unit very carefully and i am sure nothing is broken etc. So the touch is working but the screen is black. I tried 2 display units and both show me a black screen.

Does anyone know how to solve this problem? Did i forget to do something during the replacement?

Please, i need some help with this issue.

I`ve got the same problem. Have you found a solution?

Yes, it seems that the display units from HOX are not all the same. You have to check with display flex you have and compare it with the one you have new. I tried an other display unit and it worked for me.

Now i have the same problem for my friends HTC One X. Were looking now for the right display unit..

Ive swapped a few screens over on the one x and x+, I find the screens don't show anything until the phone is soft reset by holding down the power and volume up button for around 10 seconds (until the lights flash several times and then the phone vibrates before booting).

I have also found that the motherboards do accept displays manufactured by different companies (sharp, sony, AUO.. etc) the soft reset is a required step. If an identical lcd is used there is no need to reset.

Hope this helps!
