Hey Guys,
so after having to replace my screen a cpl of months ago which worked fine (disregarding the trouble with MTK drivers and such), I now decided to replace the entire frame as the glass wasn't sitting on the frame properly and was only held in place by the transparent silicon case from Ele.
Well, now my power button doesn't work anymore. The screen lights up when I plug in the charging cable and displays charge % and the battery image.
Powering up with the button doesn't do anything. The ribbon cable and connections seem fine. Buttons click.
Unfortunately, I didn't film the entire process and I now realized, that I have one small metal plate left. 0.1 cm x 3 cm in size, very thin.
I suspect it's the reason the power button is no longer functional but I cannot seem to figure out where it belongs. I checked the disassembly movies on youtube but it does not show up anywhere.
If I recall correctly, it sort of fell out when plucking out the Screen.
Anybody got an idea?
Thanks
Edit: Ok found the position of the metal plates in some spanish video, they are part of the sim tray stabilization.
Problem remains. I am out of ideas.
CLOSED: Ribbon cable does indeed have a super small tear... ffs

I swapped a good LCD screen and memory (internal and external) cards from a 98% functioning, water damaged, Streak to a perfectly functioning Streak with a broken LCD screen. I followed all the directions I found for replacing the LCD screen. I managed to do the LCD swap without damaging either Streak. However, I cannot unlock the screen and use the good Streak now. The touch screen does not respond to any touch and the capacitive buttons (back, menu, home) do not respond to touch. The capacitive buttons light up so I assume they are connected properly. My first assumption was that I had not properly reconnected one of the ribbon cables. I reopened the good Streak and checked to connection of all three ribbon cables and reconnected them to be sure. Reassembled the good Streak, but no change in behavior. I believe this is a mechanical problem, but I don't know what else to check. What do I do next?
Locking Ribbon Cable Connectors
I guess there aren't any hardware folks reading these Streak forums. How many times have you read a guy's tale of woe and he says he followed all the instructions, but when you nail him down to the details you soon find that he wasn't following the instructions? I thought I might have fallen into the same trap (not being able to read and follow instructions) so I re-read all the instructions I had used to tell me how replace an LCD screen. It looked to me like I followed all the instructions for dis-assembly and re-assembly. Then I noticed an almost under-the-breath comment in ALPERIN1's instructions (http://forum.pocketables.net/showthread.php?t=9382&highlight=replacement) that the connector for the digitizer ribbon cable had a part that flipped up. No one's instructions said to flip this connector "lock" up or to push it back down to lock the cable in place during re-assembly. Not only is there a locking connector on the digitizer ribbon cable connector, there is a locking connector on the side button ribbon cable connector. I pushed down the "locks" on the digitizer and side button connectors on my Streak and long story short, everything is now working! Thanks to ALPERIN1 for his instructions and MARVIN02 for the great pictures of the connectors!!
Hey boss,
Sorry I did not respond to you sooner, I was on the road. Glad you are all fixed up.
Again, I will try to clarify the locks in the PDF so they stand out more.

I just got this old phone from my friend after he upgraded. It's a solid phone but I'm having 2 issues.
1. The power button doesn't have the nice clicking feel to it. I opened the phone up and discovered the power button was one that I have not seen before. Is this button soldered onto the board? I would like to replace it myself, I have tried looking up power button fixes but was not able to find any results with this particular button type. It's usually the ribbon cable type deal with the flat disk contact kinda deal. Any idea where I can find some instructions and the buttons themselves?
2. I have a problem with the phone not powering down. After shutting the phone down the phone boots right back up or the screen shows the charging animation. Also the screen never goes into sleep mode it only goes into the dim mode. I looked up this problem and it seems to be a common one, a problem with the micro usb slot. I ordered the whole usb slot and the board its attached to. My question for this one is how difficult is the install?

I just replaced the screen one of my i777's. I followed this great guide my LE55ONS on YouTube. It was for I i9100, but they are almost the same phone. Along the way in the video he explains how to replace everything in the phone, including the microUSB board and flex cable, which if i remember was a pretty easy fix. As for the power button, i would try maybe putting a little piece of paper or cardboard or foam or something inside the phone right next to the button, that might make it more ferm when pushed.
Hope this helped.
Here's the link to the video :

Thanks for the reply, yes I saw the video too, it was helpful but that dang power button is so mushy it feels horrible. A little update though I was able to fix the micro usb port by cleaning it with a brush then bending the pins towards the screen, it appears that over time the row of pins gets pushed too far down and shorts the assembly. Power problems fixed but not the power button. Only place I can find that even has the power button repair service is mobiletechvideos

You might want to check the forums for your device, as the hardware between the I777 and the T898 are very different.

Title says it all really. I dropped it, but it had the keyboard attached and closed, it didn't fall far. However, now it won't turn on at all. If I hold down the power button, it will vibrate for half a second after I hold it down for about 10 seconds, but it doesn't turn on. Nothing appears on the screen.
It's completely stock, not even rooted. Does anyone have ideas?
The LCD screen ribbon cable has mostly come loose. This happen to mine when my son accidentally dropped my prime. Easiest way to confirm this is if you have a micro HDMI cable. Just plug the tablet into a TV and see if you have a picture. If you do then it is the LCD ribbon cable. The battery sits right under the screen ribbon cable and all it takes it a drop and a shift movement of the battery and the cable becomes unplugged. Just take the back cover off the tablet using the updated videos on XDA on how to disassemble the tablet. I used a little pick and two credit cards. The back cover comes off pretty easy and it is real easy to do - REALLY EASY. You will then see the ribbon cable above the battery. Just plug it back in better and secure it with tape. Power on the tablet if you want to check your work. If it works then reverse the steps taken to open up the tablet and you are done. While your in there you can tighten up the "screen" screws if you have screen light bleed too. Hope this helps you.

I think you are right! I plugged in the HDMI cable and got a signal.
Now I'm going to try and take it apart. Wish me luck...You don't happen to have a link to the guide you spoke of do you?
Thanks!

This is the link (How to is disassemble your prime) I used. Worked like a charm to open the tablet up without destroying it up or marring it. Also look at the posts of replacing the screen. You can see the LCD ribbon cable in the pictures. Hope this helps.

So when I was replacing the screen and the frame on my phone I realized the power button had a flex cable, one gentle movement and now it broke. I was able to order a new one but it's been 3 weeks since I had the phone taken apart and I don't remember how the flex cable attaches to the frame so that the button can actually touch it? If somebody could pop off their case and take a picture and/or undo their power button and describe how it goes back together that would be great!

In my experience, the power flex cable is soldered to the motherboard usually. You may have either buy a soldering iron and do the most precise work you've ever done in your life or contact a phone store. Sorry if this wasn't helpful.
The power button on a samsung note 2 that I inherited fails to work. The phone was left outside and rained on so when I first got it the screen did not work and I thought it was going to be trash however after drying it out and properly cleaning it the device screen works now and it will turn on when plugged in. I have one of the dongles that forces the phone into recovery but the power button just plain does not work. I don't know what to do but I would like to be able to use this phone.
I've dismantled a few of these phones and once I ruined a power button while sliding the the tool past it to pop the case apart. The power button is part of another assembly but can be replaced. Any version of the phone (Sprint/ATT/etc) will use the same subassembly for the power button. If that is the problem, you can swap it out.
Otherwise, you may have corrosion issues. I have brought older "dumb" phones back by spraying the circuit boards w/electrowash cleaner, scrubbing w/a toothbrush, and blowing off with an air compressor. Be sure to remove all ribbon connectors and scrub both sides of the connector. Also: DON'T JUST SPRAY THE PHONE WITH THE BACK OFF! the electrowash will stay visible the display, so do this in a controlled manner.
