How to fix Flex cable to board problem... - XPERIA X1 Q&A, Help & Troubleshooting

So my original problem is here:
http://forum.xda-developers.com/showthread.php?t=788115
And now, I am researching how to fix the flex cable connecting the LCD screen to the board to get landscape mode to automatically switch.
Any ideas or threads on how to take apart and fix this problem? Even buying the parts is probobly less expensive than buying a new xperia.

Just purchase a new flex cable and search internet for disassembly/reassembly videos.

Yup, you gotta take the Xperia apart, it's alot simpler than you think. Just takes time.
I agree, you need a new flex cable, and that cable connects to the back of the 'motherboard' and the screen. It is covered in this silvery-colored tape, but gently tugging should do it.
I've bought a flex cable cable off eBay, and it worked!

[Q] Repair Manual for Nexus one?

Ok, so i have the "power button failure" problem. No more warranty, and the local gsm repair shop can repair it, but doesnt know where the connections go, to make a bypass.
anyone has this manual, or anything that could help me?
thank you
You can't repair it.it needs a new flex cable.

I had this problem recently. Out of warranty. Sent to HTC repair center and got quoted for about $50 USD (given that I'm in Singapore, there is a physical HTC service center that I can go to).
If you want to fix it yourself, you can buy the board from ebay, this is the cheapest of them all, with tools included.

You can follow some disassembling guide from ifixit or this youtube series (very detailed, but to repair the cracked screen instead) to replace the flex cable and board. Should not take more than 1 hour. I planned to do it if the quote is higher than $80, but it's not.
Let me know how it goes if you decide to fix it yourself. Take a few pictures as you go along would be great too.

thank you guys for replying, i knew i can replace the board, bu i wanted to see if i can "fix" the flex cable. i gues there are only 2 wires inside it and i need to see where those go. not to fix it myself, but the guys at the shop. i think they can use a "strap", which is a loose wire connecting the 2 points. i dont really plan on using that button very much, i got used to the trackball wake, but, i want it to work, just in case

I've taken my 2 nexus apart, and I can tell you that there is no easy fix.
ok, update
i have fixed it in the gsm repair shop. well, they did
they waited to come in another faulty nexus to check which wires were faulty, compared them, and they put in a new external wire replacing the old one on the circuit board. everything works now. it costed me around 30 usd. anyway, i intend on using trackball wake though in the future, only if necessary the power button
Hi ,
Yes you can repair this problem. Besides the option of buying a new flex cable for 50-80 USD, I found in this very same forum a thread where somebody posted a picture and indications about how to repair the flex that contains the power button.
If you disassemble your N1 and remove the large flex that carries the power switch you will notice that i has two large connectors on the bottom end.
One of these has 44 pins (two rows of 22 pins). In the top row of this connector, counting from the right the pin number 10 is the one that turns the nexus one ON/OFF
The switch does this only by connecting it mmomentarily to ground.
TO FIX IT:
All you need is a fine end soldering iron, a good lens, a T5 screw driver, soldering wire and adhesive tape. And most importantly 20 cm of very thin magnet wire (enamelled copper wire of about 30 to 50 micrometers in diameter (it is thicker than hair do not worry).
Then solder an end of the wire to the pin #10 as counted in the way i described. route and tape the wire along the flex until you get to the switch.
the switch has 4 pins one pair is ground, the others go to pin #10 in the 44 pin connector. The ones that are gong to the pin #10 are actually on the side of the switch that has a golden "[" bracket. Solder the end of the wire that comes from pin #10 to any of these two pins of the switch. This completes one part of the process. (the most difficult).
The back of the board that holds the switch has a large ground plane. Solder a second piece of wire to this golden pad. From there, stretch about 30 mm of wire towards the upper corner of the logic board, and solder the end of it to the round golden pad where a screw goes. This is a ground point.
Reassemble the phone. Your power switch should now work again.
I hope this helps.

This may seem obvious to the tech savvy but not to all.
I bought a new flex cable/board on ebay. It was supposed to be new but it is obviously used. I have my doubts that it works. I am trying to test it before installing. If I press the power button, pin 10 (as described) should be electrically connected to ground, right? This is not the case with the board I have. Is the connection between pin 10 and the switch a direct trace on the ribbon cable or is something else involved? is there a diode or anything else in this circuitry? Does the battery holder come into play?
Other information. My phone does power on with the charger/remove/replace battery trick. All other buttons work.

[Q] The Droid 3's coax cable

What kind of function does the Droid 3's internal coax cable have? Does it work as a wi-fi-antenna, GPS-antenna or both?
I'm going to replace a few parts in my phone, but it looks like I can't do it without breaking the coax cable...just wondering if I can manage a few days without it till I get a new one..
Not sure which cable you are referring, but you should be able to take the whole thing apart without breaking any cables. If it is the one that attaches to the backplate of the phone, you have to lift up on the connector on the phone.
Pictures and more details of what you are trying to do may be helpfull to answering your question
It's the one attached to the backplate. And the backplate is one of parts I'm going to change, but the new backplate replacement does note come with a coax cable. The cable on the old backplate is impossible to remove without breaking it as it's glued to the backplate. Disconnecting the connector is not a problem.
I understand now, I looked at a spare backplate I have and the cable is soldered to the phone in several spots, that would indeed be very hard to remove, but possible with a good iron. I hate how a lot of the replacement parts out there come without important pieces, this is usually a good headache.
If you have the part in hand, it is a simple swap, try it out and see what antennas don't work by trying to connect to gps, wifi etc. If you don't have the part in hand, I would look elsewhere to obtain one.

USB Port Fix

Any one know of a company that can fix the USB port on a HTC Raider in Canada. Rogers wants to charge me $250 to fix it.

You could probably buy two new Raiders for $250! Replacement might be the best bet, as you can likely find one on Kijiji for $100 or so. If you have a local cell repair joint, give them a call, and see if they offer the replacement. It might be tricky since the USB on the Raider (as other HTC phones) is actually a special type of HDMI jack that also has USB (known as MHL).
If you're adventurous, you might track down a broken Raider and attempt a part swap yourself. I've not seen the inside of the unit, so I can't say how easy or hard that would be at any skill level...
Hope you get it fixed up!
The part is on eBay you can always try to do it yourself should be a few small solder points

A friend needed this. We ordered one off ebay ( http://www.ebay.com/itm/OEM-USB-Pow...328529?pt=PDA_Accessories&hash=item27c422a1d1 ) and although it required opening the phone up and voiding the warranty, it required no soldering. He doesn't open electronics up very often, and said it wasn't very hard to do.
i was babbling abt this in a thread in the dev forum, thot i'd best do it also here in the proper forum for it:
i changed the USB port in my Raider, was very simple. Six little screws, two different lengths so keep track of them. One screw also holds down the teeny cover under which is where the tiny connector resides that connects the port to the fone circuit board. Once the fone is back together that's where you make the final connection between port and fone.
Slip off the battery cover, undo the six screws, take off that tiny little cover. Carefully work off the entire back housing. There's no front housing, just the screen glass and the fone circuitry bundled together.
Micro-USB port and ribbon connector is fastened to the housing with two more of those little screws. Change out the port with the new one. New part may not be an exact duplicate of the old part: that's ok. Reassemble the fone. Under that hole left by the tiny cover, press home the miniscule plug that connects up the port to the fone.
Put back the tiny cover, fasten back all the screws, and you're done. Port cost me $9 USD plus shipping on ebay.

Hey, dude, I know this thread is a little old, but can you PM me the link to where you bought your USB port? I think I need to replace my port (issues connecting to PC and charging requires wire wiggling), but I've read about certain ports not working with data transfer and only charging, and I don't want to make that kind of mistake.

Loose USB port

Did a search but surprisingly couldn't any similar threads.
My USB port has become gradually looser to the point that charging it means resting the phone in such away that it applies pressure to the USB connection for it to make contact and charge the phone.
Initially some cables worked better than others but they are all starting to fail now.
The magnetic port has also failed. Does anyone have a solution for fixing the USB port?
Hi
You'll probably have to send your phone to a repair center to replace the "exhausted" usb-port. If you are handy with a soldering iron and have the guts to crack your device open, you should be able to acquire the parts ad i.e. eBay or some such and replace the port yourself. Can't be too hard seeing as it is only a four or six-pin connector that attaches to the board...
Can't figure out why the magnetic charging-port won't work though...

Hey. Thanks for the reply.
I used a magnetic connector that was too powerful I reckon and eventually pulled out the magnetic port. I glued it back in but was never the same after that.
On the USB port, I have the phone for 18 months - should I be able to get it repaired under warranty?

Charging Port Replacement

Whenever I plug my phone into my computer and wiggle it around a bit it disconnects. It's a brand new cable too. I'm assuming I need to have my charging port replaced?
Never assume. Check to see if it happens with a different cable first. If it repeats with the second cable, then take the phone in for servicing.
It would not be worth to replace the charging port. It is time to get a new phone, isn't it?
It would be far less expensive to replace the port than to replace the device. Besides, without actually taking apart the N6, we don't exactly know what's going on. The connector could truly be damaged, or it could be a simple issue of the connector losing connection with the motherboard due to a bad solder joing; something that some skill with a soldering iron could resolve.

Indeed, it is that time. The only phones that meet my needs (fast wireless charging, USB 3.1, Bluetooth 5.0, microSD, etc) are the s8s so I'm going to wait for the Note 8. The Essential PH-1 is also on the radar but I really don't want to go any smaller than a 6" display.

Have you tried to remove any lint with a toothpick or similar tool? Doesn't cost anything to try a thorough cleaning before anything else...
You could also use a magnetic micro USB adapter, people say they fit very tight in the plug

I'm pretty sure the port was just dirty. I blew in it (like the old Nintendo games) and now it stays connected while wiggling the cable around rather forcefully.
