Unhappy KT Screen Flickering

Hello all,

Looking for some help here...

My kindle touch screen flickers continuously for about 30 seconds then it freezes for about 5 minutes before it restarts to do the same thing again. Continuous loop. This goes on till the battery dies.

http://www.youtube.com/watch?v=libzo...ature=youtu.be

Please see the linked video below for a better understanding. (In the video, I am trying to boot into diags and follow kubrick instructions but the kindle freezes before I can enable usbnet.)

Please advise. Any help appreciated!

AFAIR you don't need to use the diags and usbnet for Kubrick?

just follow the instructions on the Kubrick screen:
Use the magic key to switch to fastboot mode while it's connected to a PC.

nope - not required.

make sure the battery is fully charged, then follow the KUBRICK instructions **exactly** (which includes charging the kindle).

This looks like a hardware defect. Sorry, but there's probably nothing you can do about it.

kubrick 3.4 calls for diags mode and usbnet in step 4 or 5 of the step by step wizard.

Hardware defect is what I was afraid of.

Thank you all!

Edit:

Any idea what the defective part may be? I could look into acquiring the defective part and attempting a repair.

Have you looked at the hardware ?
You are not going to replace parts with a soldering iron, ready or not.

It requires special SMD re-work tools.

No, I haven't tried to open it up yet. I've toyed around with ipods and cellphones though.

Hmm...are you saying its more trouble than its worth?

I am saying it takes very special tools.

Just had a look at the hardware!

Was surprisingly very easy to take apart. Didnt really need anything much other than a philips screw driver and a thin flat tool to wedge it open.

I'm probably going to have to change the motherboard and/or screen by trial and error. Now to obtain spares...

That was likely more professionally done!

Mine was a lets try take it apart and see what happens...but turned out to be surprisingly easy. Though I did bend 1 clip a little in the process.
