    I've just replaced my HTC One M8 digitizer assembley and the phone will not boot up and just displays a rainbow array of pixels covering the screen. Picture below.
    Does anyone know what might cause this. Before I replaced the screen I replaced the SIM card assembly and tested before I reassembled the phone. In the process of re-assembly I tore the ribbon that was attached to the screen, hence the need for a new digitizer assembly. I've checked over and over to see if there's a loose cable or damaged part but to no avail.
    Can anyone give some advice?

    Main logic board or something else is zapped possibly? Did you take any anti-static precautions during the repair, like a grounded wrist-strap?

    Damn it! I'm an ex-BT engineer and should know better. I didn't use ASP so I might well have blown something. Grrrr

    I originally opened it up to fix the speaker then I had to replace the sim card holder. Tested and worked. I put it back together and it wouldn't recognise the sim so I put in a new sim card holder and tested before putting it back together and it worked so I put it back and it didn't work. D'Oh! Took it apart again and notice the copper ribbon to the digitizer had torn. Ordered new digitizer and here we are.

    Looks like a new phone needed.

    Thanks for your help.

    Mark, I'm an ex-BT engineer as well, and notices like this were very familiar to us. des-06722_3_5_1.jpeg

    Ahh! the lovely anti-static notices. I used to have an ESP wristband on constantly. I'm kicking myself now. How to trash your phone 101. D'Oh!
