you know whats funny. I just figured out ( last night , i was up all night working on ipod touch 4's) how this is done.
1 thing is for certain. most every white screen that appears to be ruined. is actually good.
the other thing - if the white screen effect is not solid but instead has streaks or partially covered reddish lines. That is a bad screen. it's the screens male end or the mother boards female side. the pins are crossing from being bent or broken off or whatever. or it could be the ribbon jacked. sometimes you can straighten the pins back out and get it to work but i do NOT want to get into that because it's so hard it just !@#$%^ me off to think about it, I will tell you this though, you will need a huge lighted magnifying glass to do it and good freaking luck. moral of that story is do not push that plug to hard. LOL
your white screen problems are not from a bad screen, your white screen problems are from the gpu getting shut off and on at the wrong times or super fast or when ever it just doesn't like what your doing. this can happen at anytime during the fix. It;s really easy to bump when all this apart, it's due to the charge in the battery and just bumping any little thing can send a signal to the ipod accidentally.
Bulk sellers are not trashing your returns, they just sell them again. no joke. if it looks fine, no cracks or scratches, they will just sell it again. you might get a new one, you might get the same one back. and guess what happens when you get it? it works.
Some of you guys are not being honest. you say that you think your screen is a bad one and "help me I want a fix for this" and blah blah blah. but what you really mean is you got it to work but then later when you were trying to get everything right, it quit working and went a white screen and now you can't get it back on like it was before. I think that's because no one wants to admit they jacked it up.
well you did jack it up but it's fixable. That hold the volume button thing hasn't worked for me reliably. it does sometimes but I believe it's because at some point while doing that the machine just gets too may commands at one time and shorts it self out for a second. POOF there lies the fix. If you have tried to do it that way and it doesn't work you can just short it out yourself for a second. take the metal center piece back out. see by the home button controls Pos and neg and there is a another on the middle of those two 9 can't remember what that says at the moment.
use something metal, a short piece of copper wire with a another short piece of copper wire wrapped in the middle is perfect. you want to make a 3 way connection for just a moment.
you want to touch the center of the home button, the sliver metal around the bottom of the home button ( frame piece with the goo in it. and the POS terminal for just a second. now plug your white screen failure back in and poof. it is perfect.
I came to this conclusion after a few tests and one of the ipods I was working on that was doing this was set aside because I was so frustrated with it. I left it set for so long the battery ran all the way out. it worked when i recharged it and and plugged the same screen back in. also powered several cracked screens.
so wha laaa. if you do not believe me then i would like to buy all your white screen failures please./ LOL I will give you 3 bucks each for them. LOL
Man, that would be great, Id have a pile of them and never have to order another, I'll be rich!
PS. I am not some kid that thinks he knows everything. LOL I am a Monster 45 year old hairy man with fingers way too big to be messing with these tiny little screws. I normally just deal in car audio( KICKER ) but I got into doing this because I was getting a lot of customers with broken ipods that they were using to push signals to their head units.
when you are dealing with amps and signal processors and huge car audio systems the cardinal rule is disconnect the battery when working on the system. the power is WAY hi in the audio systems so when something like this thing with the ipod happens it FRYS STUFF. I mean it will Blow stuff up, ruin thousands of dollars worth of electronics or even burn your car to the ground.
so it;s kind of cool the electrical systems in these are only very small and all you have to do it is this fix to make it all work again.
Ta Daaaah !
