Look above pictures please.
I sold a phone on ebay ( phone was about new) and buyer said phone isn't working so ebay told me to do a refund and get the phone back. Phone came back like seen in the picture.
Any ideas on how to fix this? Can it be that somethink got out of place during shipping?
EDIT:
Update info:
I removed battery cover and battery, squeezed gently all over the phone, put it back and phone started normally, after first reboot it became grainy again.
Can it be that something got unplugged?
I have no warranty on this phone, so to open it further will not void any warranty, can anyone point me what should I look for?
Awaiting any comments,
Thanks
help
Any one to pass an idea here?
Solution
Well, I managed to fix this phone and thought to come and share what I did.
First I kinda narrowed down the problem to lcd or main pcb board.
As I have two htc sensations 4g (t-mobile usa) Ithought I will open both and try main pcb board from bad phone on good one.
Problem was on main pcb board as it did the same grain display with it on good phone.
After I put together phone which originaly worked fine I examined this bad pcb board and everything seemed fine to naked eye.
I connected all cables and flex cables and before putting back cover with 6 screws I tried it once more and its was same grain picture.
Then I gently pushed over video flex cable connector and phone was all fine. I removed the battery (which at this point I was holding in place with my hand) and used a piece of wood to push that flex cable connector some more as it seems that was one part which was doing all this.
Seems that from fall this socket (connector) moved out of its place.
In case you need to do this or anything inside your phone I sugest you watch this youtube video:

I didnt understand much of what the guy was talking but video quality explained it all.
I hope no one need to go through this, but if you do then my experience with it might help you.
Check picture of connector in question:
Bake it
I had the exact issue and after I tried everything and was ready to order one from ebay I put it in the oven for 6-7minutes at 360 degree.
Its working perfectly for last 2 months now with no issue.
NOTE:
Please do this as last option as I did.
A bit of the black part of the antenna that is circled in the picture kind of broke off when i was disassembling my phone. I think this is the thing that controls your phone signal. If it is, does anyone know if this will stop my signal completely and mean I have to buy a new antenna? I have no way of checking because I broke the cable connecting the antenna to the main board (don't ask) and the replacement doesn't arrive for a while. (The picture attached isn't the picture of my exact phone. It's from google images. But its the same model) The other 4 thingies are still in tact but the thing circled is broken off.

This question cannot be answered without testing. Try it, if it works, the answer is no, if not, the answer is yes.
Unfortunately, waht exad said. Stuff like that is so unpredictable. Keep in mind that pretty much EVERYTHING on modern phones is tiny. There are entire chips and resistor packs that would be described as miniscule, but are critical.
If you have it apart already, and can find a replacement part and it's easy enough to replace, I'd hedge my bets and just replace it while I'm in there rather than putting it back together and learning the hard way that you have to go through it all again.
similar issue
Have the same issue.I accidently trapped gsm antenna wire between housing and dock connector. Its been bent in 4 or 5 points.searching for network gives error."error while searching for networks ”
Please suggest what can I do.
Replace the part.

Hello, I have a problem. Hoping someone has an answer. I have a Verizon HTC M8, yesterday I decided to disassemble the phone to just see what the insides look like, I didn't touch any other part, I tried to remove the top motherboard but I stopped because any further would damange the top board. Anyways, the GPS was working fine until I took the unit apart.
The problem: GPS location on Google map is at least a block off (tried different map apps, all are offset) and is facing the wrong direction. And GPS following is very very slow. Now I don't know if it has to do with an GPS antenna or what, maybe one of the prongs is not touching antenna, I've taken a photo of the phone from inside and I would like to know which area of the phone is exactly the GPS or maybe causing the problem . I've also attached a photo of the GPS problem, you can see in Google Maps navigation the pointer is wayy off the direction area. Please advise.
Question: What part may be causing the problem? (my guess is its the copper prongs from A-G).
Please help.
Thank you!

In my opinion, this phone has kind of wonky GPS reception anyway. It's hard to tell exactly what's causing it, but my guess is that it has something to do with an unwanted contact, or the antenna itself, touching the metal casing directly. Also, You may have possibly loosened the connection of the GPS antenna when you played with the motherboard a little.
I'll try to find some better board schematics from the motherboard, maybe tomorrow when I have time. I haven't really been able to find some good diagrams on the actual phone internals itself. This phone is really difficult to take off and not too many people attempt it.
I would try to make sure that the internals are properly shielded when you put the case back on, and try to keep all of those contacts covered as much as possible when you throw the case back on. See if you get better GPS lock or if it fixes it all together.
Edit: Actually I changed my mind, I think all those contacts are supposed to contact the case to amplify the signal. Try to get all the contacts to touch the case as much as possible when you reassemble it. I think it's either the connection from a-g area, or on the bottom half k-n or even the q connector. Is your WiFi or NFC giving you any issues as well?

@ Badusername, Thank you for your reply . Yes everything else (wifi/nfc/bluetooth) works perfectly fine. The accelorometer seems to be fine as well. Only part I try to remove/touch was from A-G area motherboard but that was held with adhesive so I didn't touch it any further, I didn't touch any other part. My guess is it's A-G area but not sure exactly which one is the GPS antenna so I can try to adjust it (if possible).
I jave the exact same problem. Did you figure anything out yet?
Any Updates?

Did you bend any of the copper prongs so that they no longer touch their antenna? That's usually the problem.

Not sure which prongs you speak of. I reopened it and all antennae look connected and right but still no go...

Can't find a schematic anywhere that shows which antenna or prongs are gps related so I don't know which prong or antenna to mess with. I'm surprised there are no basic schematics anywhere...

I believe it's in the top board so make sure the ribbon cable is secured and not damaged. The metal prongs usually need to make contact with the case itself which often has the actual antenna stuck to it.

Thanks for your help so far. Checked all prongs and ribbons on top left and they all look normal. They all still have a spring to them so that theyll touch the contacts on the back of the outside case. I'm out of options without finding exactly which part are gps related....

Is there any way to purchase the gold colored motherboard clips/pins that make contact with the case for the GPS module. While attempting to fix mine, the clip broke. I was looking to purchase this clip to attempt to solder it back to the board.

I'm in the same boat. I don't think there's a way to replace the clip itself, only the board that has the clip on it. It shows up as a result for "HTC One M8 Motherboard Flex Cable". Here's the one I'm buying, it's around $60. You can see the little gold tab in the picture for it. Looking at that board's location on the phone, it looks like you'd probably have to remove the motherboard to get to it and replace it. Sounds fun. I had my phone apart for a relatively simple USB port replacement.

I know this is raising the thread from death but I too broke my tab off for the gps. I was able to fix it using a trimmed piece of thin sheet aluminum that I salvaged from an old Airport extreme. I trimmed it down to the size of the tab on the motherboard and used some conductive adhesive to stick it to the solder pad that the old copper tab was attached to. I then trimmed to down to length to touch the casing when the phone was reassembled. Its been working great now for a few months and its actually a much sturdier piece of metal. I can't say objectively since I don't have data to back it up but it feels like I get a faster GPS lock now.
This is probably a stupid question but I figured I'd throw it out there.
I have installed a Tab 2 into the dash of my car. It is integrated into the dashboard now and wired up to the stereo. I would like to have a dash cam. It would be nice to be able to use the cam already in the Tab 2, since it's just sitting there. But this would require me to remove the cam from the board and make it external. I've watched the disassembly videos and I see that the camera appears to be wired through a printed circuit. So I'm assuming it would be nearly impossible to remove this cam and make a longer lead for it so that I can mount it external to the Tab itself? If anyone knows of any easy way to do this, let me know. I'd like to avoid the expense of buying a dash cam. Also, I don't think I have the space available to plug one into the Tab.
Well, on the P3xxx the _backside_ camera is actually plugged into the motherboard (on the bottom side), though if you want to turn that camera into a "dashcam" that may require some skills on your behalf.
You would need to extend the flat-flex cable from the camera ... either by using a matching socket and plug (possibly hard to find, and you also need to solder leads/wires to the pins that are insanely close to each other) or by soldering leads/wires to the pins of the existing socket/plug or in place of the existing socket/plug (requires way above-average soldering skills as you need a low-temp iron and solder that melts at low temps so you don't burn the plastic of the flat flex). If your skills, and equipment, don't stand up to the task of soldering on a flat-flex (remember, the pins, meaning the pitch between them, are insanely close to each other) you're already out of luck.
However, even if you manage to extend the connection between the PCB and the camera and it does work, the question is: "How long can the "cable" be before the signal doesn't get through anymore". That's more like "trial-and-error" than "something that can be estimated".
Let us assume you manage to extend the interface long enough so you can sneak it through a hole in the dashboard you then need some enclosure for the camera to mount it to the surface of the dashboard ... that either requires you find something that is suitable, or you have a 3D printer to print yourself a custom enclosure.
Going by your post ... I think you shouldn't touch it or even try it - given you didn't even realize that the camera has a socketed connection to the main PCB. You may be better off buying a cheapo dashcam from your nearby supermarket or electronics retailer, that's the better option over possibly damaging the hardware of the tablet while trying your solder skills at it (unless you happen to be skilled in hacking about on hardware)
I did realize it was a socketed plug, as I stated in my post, I watched the disassembly videos and I've seen replacement cams for sale. So yes, I clearly knew that. That was the entire purpose of my post. I was hoping someone had a simple solution, possibly knowing of an extension cable with the socketed plug, but knew that was a pretty long shot, which I also stated in my post. But I was throwing it out there, just in case someone knew of a simple option. No, I do not want to mess around with soldering, at that point it's not worth it and easier to buy another external cam. Thanks anyway.
