[Q] black screen and white stripes (CM9)

[HibikiTaisuna]

Update4: (14.01.2012 1244): This method didn't work. I sent my Defy back to Amazon and they repaired it under warranty
They will send it back to me next week. It seems that it was a production failure.

Anyway, thank you very much for your help cengiran!

Hi Guys!

I do have a big problem with my Defy.

I updated the CM9 onto the newest version and had to activate my google-acc. I didnt finish the smartphone registration and put my Defy to the side. Today morning the battery was empty and I reloaded the battery. After that I turned the device on but the only thing it shows is a black screen with stripes (even in cwm and bootloader). Does anyone know how to fix my Defy??? The Defy boots completely but the screen remains crappy ;(

Please help me!!!

With best regards

Edit1: (27.12. 1421): New day, same problem ;( Still found nothing helpful...

Update: (27.12. 1736): Flashed a new fixed sbf with RSD Lite. Still the same problem. Could it be a hardware problem??? LCD-Display broken or stuff like that? Didnt throw the phone through the room like others (^^);

Update2: (29.12. 0801): Error still remains... Is their anyone who had the same problem or who can help me? Do I have to replace my Defy? Might there be problems with Amazon (warranty) because of root and stuff like that?

Update3: (30.12. 2217): Now trying the tip by cengiran:

hi there,
i have the same issue but not due to CM9 installation but due to hardware issue. judging by your writing, this has nothing to do with software and so hopefully this helps.
My screen is also black at boot with some part of it are stripes (and some bad white and blue square w/ noise) and looks like a broken LCD monitor.
This is due to hardware malfunction (probably your battery went bad) in my defy the battery have some water damage and somehow it screws up the voltage regulator or the grounding part, but does boot with the correct screen using some techniques on every boot.
Try this solutions:
1. completely discharge your battery, take it off, hold the phone power button for 30 seconds to make sure every power stored in phone is out. Put the battery back on and connect the charger while the phone is still off. DO NOT turn the phone on. Your screen will look all mess up when showing the green battery, wait until 3hours and take a look at your screen again. In my case, the screen showing the the battery charging image is clear again after i did this. - this is to make sure that your screen is actually okay. Try turning your phone now and see...if its still bad then go to step 2.
2. turn phone off, open the battery case. Connect phone to charger again without turning it on. The phone will do its regular boot up until showing you the battery icon again. when the battery icon is there, PULL the BATTERY out of the phone (the charger cable is still connected to the phone). the phone will reboot itself with the correct screen usually, if it doesnt boot itself, quickly pull charger cable and reconect it again (with the battery still detached from your phone).
mind you if you get to the okay screen, this will not boot your phone, this will bring you as far to the battery icon with a question mark (we know for sure is just battery issue now). regardless screen is okay or not, proceed to step 3.

3. turn off phone, battery out of the phone, and press the power button for 30 seconds. release power button and re-insert battery and boot. (usually still bad but this is to ground any left voltage in there). after it boots (with the bad screen, if the screen is okay then proceed to using your phone like usual) before the LED lights blinks (the 2nd.init lights) pull out battery, press the power button for 2 seconds, re- insert, and boot. repeat this as necessary until it boots with an okay screen.

tips:
battery empty is for step 1 only, steps 2 and 3 needs power form the battery.
You can actually go to step 3 if you wishes, but my experience is by using step 2, it will talke less retry until i boot with the okay screen (i need to do this everytime i restart the phone mind you, so its a daily thing) .
the LAST tip: there no rules of thumb on how many retries it needs, if you have been retrying for 20 minutes on step 3 with no avail, revert back to step 1 or 2 and retry step 3. If this is sill fails, then you might need to consider purchasing a new battery, or take it for a repair!
Im still waiting for my new battery, but now it only takes me 5-6 tries before it boots correctly, in the apst it took me 15 minutes of constantly retrying so be patient, but still need to set a line when to give up!

Hope this helps and good luck

how does it go?
to completely discharge your battery is tricky...and actually not recommended because i heard our kind of battery should never went completely gone, it can mess up the battery capacity. i suggested it because thays what i did and in this case, battery cost much less then actual repair,,call it collateral if you will.
heres what i did to completly discharge it...after the phonse turned off automatically due to battery running out, it still have around 2% in it so reboot and enter 2ndinit/boot loader. let it stay there until the phone turned off on its own again. in 2nd init, the phone wont turn off screen so it will continue using whatever is left in the battery. keep n mind that even at very small amount of juice left, this process can takes up 2hrs or more.

...can't post a photo of the screen...

Hi cengiran,

thank you very much for your help. I will try this immediately. The only problem I do have that my battery doesn't want to go empty XD
There are so many people who want their battery to last as long as possible and now I want to get it empty a quick as possible XD Irony
Since 26th December 1004 pm my Defy runs with one single battery charge XD I think thats a pretty good battery life for a smartphone ;D

If your tips don't work I will sent it back to Amazon and hopefully they send me a new one or repair my old one.

Thanks again and I will post if your method works.

With best regards

HT

P.S. Amazing that this thread is the 1st Google search result for this problem XD

This is due to hardware malfunction (probably your battery went bad) ...
Try this solutions:
....
2. turn phone off, open the battery case. Connect phone to charger again without turning it on. The phone will do its regular boot up until showing you the battery icon again. when the battery icon is there, PULL the BATTERY out of the phone (the charger cable is still connected to the phone). the phone will reboot itself with the correct screen usually, if it doesnt boot itself, quickly pull charger cable and reconect it again (with the battery still detached from your phone).
mind you if you get to the okay screen, this will not boot your phone, this will bring you as far to the battery icon with a question mark (we know for sure is just battery issue now). regardless screen is okay or not, proceed to step 3.

3. turn off phone, battery out of the phone, and press the power button for 30 seconds. release power button and re-insert battery and boot. (usually still bad but this is to ground any left voltage in there). after it boots (with the bad screen, if the screen is okay then proceed to using your phone like usual) before the LED lights blinks (the 2nd.init lights) pull out battery, press the power button for 2 seconds, re- insert, and boot. repeat this as necessary until it boots with an okay screen.

Thanks a lot, a mix of these two works for me !
My problem arise after a month that I switched off defy for replacing it with a new smartphone (Xiaomi M2S).
I removed battery to force it to switch off, because I couldn't see anything.
I replaced the battery, I connected the phone to charger and after ten seconds (more or less) I removed the battery.
At this point I can see the Motorola logo. I've re-inserted the battery and it shows that it is at 97%.

For sure, the lcd is working
