Mytouch 4g Power Button Ribbon - myTouch 4G Q&A, Help & Troubleshooting

So while replacing the digitizer on a mytouch 4g I broke the ribbon that connects the power button to the motherboard. It is broke directly at the power button location, not at the motherboard location. Can this be re-soldered? What would be the best way to fix this? I can buy a new power button & ribbon at a local parts store for $90. Any Ideas?

sent you a PM.

I am having this same exact problem.Broke my ribbon connector replacing Digitizer..At least it was not a client's phone..Any suggestions.."WE NEED MORE POWER CAPTAIN"

I have done the same thing. Is there a way to fix this?

I honestly think it would be wayyyy cheaper to just buy a new set thing.
Nick'sAMytouch4GLover<3

what "new set thing"?

i broke the power ribbon as well..
can not find a schematic to solder on my own wires either.

Here is the instruction to fix your problem:

Needed Button Strip - Anyone have HD2 Parts?

In the process of replacing my lcm, I managed to tear the button flex cable that connects to the mainboard.
I am currently looking for a the button flex replacement. What is the best way of tracking something like this down without going to HTC?
If there is no current seller/merchant available...Um...Is anyone selling an HTC HD2 for parts!?!?!?
Pics included...You can see the button strip, and the little 45 degree angle break on the flex..SUCKS!
I saw the break... Man, that's bad luck...
I hope you find a new button strip. The only other solution would be to solder fine wires from the point I highlighted on the photo. But that is very very very difficult... If you decide to do so until you find a new button strip I would recommend you to let an expert solder it, for example a television-technician. That shouldn't cost you more than a bier for the technician!
Wish you luck!
This just in, I have since purchased a broken hd2 and replaced the button strip. It has a light adhesive and is mounted on two small plastic posts on either end. To loosen the adhesive, just apply gentle heat (blow dryer) and GENTLY peel off. You might come across a stubborn part and want to give it a harsh tug, but you need to methodically peel it up using some sort of flat piece to get from underneath it.
Another torn flex Anyone has spare one or knows where can I get it?
I'm sorry but can't help. I get parts for iPAQs from iPAQ Repairs in the UK. I'm surprised there isn't something similar for HTC parts.
I'm interested in what an 'lcm' is. I've seen it mentioned but with no description.
i need one of these too. i hate htc's policy in not selling parts directly.
This button board should only be like upto $40 usd.
im needing a main board charger soxet broke if price is right ill sell
I have the same problem ....you solved?
where did you buy?

You should be a good electronic technician or know a good one. Otherwise I advice you not to try. I am a ordinary technician and I can say that in my case it was very very difficult and even if I tried hard, I wasn't able fix all connections. Only two of my buttons work right now.
How to Replace Button Strip?
Anyone know of a link showing how to replace this strip? Either I can't find key words for a search or there aren't any good videos out there. - thanks
Good to hear I'm not the only one to snap it so easily. Ordered a replacement from e-bay.
Sorry to dig up an old post but, I need that little wire that connects the wifi/bluetooth module to the main board. I replaced the digitizer in my phone and I somehow jacked up one of the ends on the cable. Anyone out there have parts?

broke the antena...

I was opening my phone all reckless... and I broke the antenna cord. I tried saudering it. But it didn't recover my signal. My home, menu, search and back buttons don't work either... what would cause that. Would a copper wire replace the cord?
Edit: Shiet. I seem to have broken a flexible as well. The one for the touch buttons.
To repair the phone I need two things, the antenna cable and the cable for the bottom buttons. Where Can I find replacement parts?
Edit 2: http://www.globaldirectparts.com/OEM-Samsung-i9000-Motherboard-Flex-Cable-p/smsng6087165.htmi
I was just about to give away my phone on ebay... until I remembered this site when I was trying to get an FFC. Its going to run me ~$90 to repair the phone.

Nexus One power button fix

I just bought a replacement power button/ flex cable for Nexus of ebay. Took me around 30 minutes to replace it but its fully working right now. Its around 30 £ .
Item name it "Flex Cable Repair Parts for HTC Google Nexus one G5 1"
Just thought i let you know .
Any pictures?
Is it a tricky fix? I replaced my digitizer just fine so hopefully this wouldn't be a major repair job in comparison. Would love to have my power button working again!
I don't understand why you fixed it yourself, I sent mine back to HTC.

How much did it cost for the repair out of interest? Did it take them long to get it back to you?
Just curious if to you it looked like a bad button connection or a bad cable? I know sometimes the buttons get crud in them so they dont make a proper connection...
Great info. Too bad we don't have step by step pics. How did you take the phone apart and how deep did you have to go?
Does anyone know why the power button breaks? I have my N1 a year now and (luckily) i never had a HW issue. anyways i was just wondering why it breaks .
Step by step pics would have been nice.

The power button itself has a small cylindrical piece of plastic which pushes against and presses a small connection that sorta clicks (Which gives you the tactile feedback you feel). I think the problem occurs when either 1) The piece of plastic either bends/breaks/gets damaged in some way that makes that contact much harder to produce 2) The connection is connected to the phone via a cable/flex, however due to the Nexus one design it is bent around in order to be below the power button, while this is fine for the majority some devices, including mine, have seen the flex become damaged for whatever reason and either function intermittently or not at all.
It's also interesting to note that there is nothing holding the flex or the connection in place except for the design itself i.e. the battery bay plastic holds it all in place. My power button was never that responsive (But got progressively worse) so this may explain why.
Its always flex cable breaks and there is no way you can replace just the flex cable.You can find plenty of disassembly instruction over the net and yes you need to disassembly it to the pieces( still less to do than to replace digitizer.)I had a seal broken so i couldn't send it to HTC.

I did some googling and found a few images of that component, I remember taking it out and it was pretty simple so it should be just fine! Thanks for the info!
Is it the Power button part that you changed ?
Hi,
I have found a photo of the power button part, can you tell us if you changed the full part shown on the photo ?
androidguys.com/2010/09/08/manage-nexus-broken-power-button
And i think you paid it way too much expensive ?
Thanks.
I just replaced my flex cable as well as the loud speaker as well.
iFixit has a few pictures and there is a video on youtube, of the taking apart process. Unfortunately I can't post links
There are two little rubber parts that will likely fall out during the mainboard removal. One goes underneath the connector beside the sim card and one is a part of the microphon.
I wish I could have taken pictures of where those parts go, but alas, my only camera right now is my nexus, so....
BTW, I bought my parts at Mobile Brando. Quite well priced as compared to many other stores of the kind.
was it the whole board that you've replaced? or just the flex cable for the power button. can you further elaborate the steps that you've done?
So this is the item that you purchased? http://mobile.brando.com/google-nexus-one-mother-board-flex-cable-ribbon_p6193c1023d88.html
Can you confirm that the 3.5mm jack is on that board? Additionally, is that motherboard and flex cable for the AMOLED version or the SLCD version?
Do you need to remove the screen and risk getting dust inside there to swap this part?
Hi,
That's exactly the item, at that very same store. I also bought a loudspeaker as well as both back covers there. The audiojack is on board and I believe the flex cable has nothing to do with the screen type. The screen does not have to be removed.
I used those pics: http://www.ifixit.com/Teardown/Nexus-One-Teardown/1654/1
and this video: http://www.youtube.com/watch?v=cznogushN34&feature=player_embedded to figure out how to do it.
Basically, it's quite straight forward, given that you aren't a clumsy oaf ;-)
Remember the two rubber parts that might fall out when you pull off the mainboard assembly. (one at the bottom, for the microphon (http://guide-images.ifixit.net/igi/fpRmPyN6h12mtNvt.huge ,a bit to the left of the plastic tool) and one at the connector beside the sim card (http://guide-images.ifixit.net/igi/EOfeocuwhCRASB6M.huge , on the left part, somewhat down from the serial number sticker).
I have this probleme, but this part costs too much :S....
10. pin ON OFF way in board socket... u make jumper to on off buton
I have replace Power button for my N1. But you can reset your N1 by do'n need it. Except when you want flash rom!

[Q] Help! Broken Ribbon Cable

In the middle of disassembling my Legend to replace a bad digitizer, I broke the ribbon cable connecting the power button to the PCB. I haven't reassembled it yet, but I can't see how it's going to work.

(Sorry I can't post links because of post count.)
If anyone knows what the best way to repair this would be, I would be most appreciative. Thank you.
EDIT:
It seems this is the piece I need to replace.

Anyone know where I could go about finding one of these? The part number turns up nothing on Google.
I would find a service center and ask there, or I would solder it , it's just two wires....
But be sure you purchase a part with the ribbon cable on it, what I've seen it didn't look like it was there...
Good luck...
Called HTC service center. Unfortunately they don't sell parts direct.
I thought about soldering it, however the ribbon broke so close to the base that I am not sure I would be able to get access to the conductor.
Anyone have a trashed Legend that I could buy for parts?

Phone power button now working even after replacing

I ordered a power button because i broke the button itself on the ribbon and when i replaced it the power button wont work but the vibrator works. Idk if the new part is just dead but im not using up my weeks and dollars just to end up with a faulty power button. I just want to install a custom rom as stock samsung sucks because ram is always overloaded, if theres a workaround for installing a custom rom without a power button that would be greatly appreciated.
P.S. I have tried cleaning, lifting the contact pads on the ribbon by inserting a piece of paper below it.
The power button is a core function. Check continuity of the replacement switch/ribbon cable. If good it maybe a mobo failure.
The N4 was a great phone but it's very outdated at this point. A newer used phone might be a better plan.
