[Q] GPS Antenna fried? pics inside! - Desire HD Q&A, Help & Troubleshooting

Lately, i've not been getting any GPS fix. I've tried the conventional way, putting pressure on the antenna cap, and using several apps. nothing worked.
On youtube i saw a way to pop off the cap of the GPS antenna and flashlight.
When i opened it, it looked like this:
2 black spots on the contact!
What's that? fried? so that's the reason for no connection at all?
so what next?
1: a blob of solder on it?
2: connect it with a wire between the 2 springs?
3: buy a new cap?

Where do you see black spots on the contacts?
And if you had black spots on the contacts, the electronics would probably be fried too.

well, its not visable on the photo but in the circles is definitly a black spot!
here it show's up as grayish :S

dont worry, its not fried.
the black spots are the normal signs of wear.
i (and many others) have/had the same problems.
some soldered wires between the 2 golden springs.
another thing you can do is lift the golden springs just a bit, so that they make better contact with the antenna cover. but thats not permanent and in a few weeks, you will have to do it again.
i just put a (little) blob of solder on each contact of the cover.
be careful if you do this. the golden traces of the antenna are just painted on and you burn them really quickly, so best just put a bit of solder on the tip of your iron and briefly touch the contacts, because they are so thin and warm up really fast, the solder should flow over quickly.

Ok, I'll try that, if not, i just order a new antenna cap
I'll keep you posted if it works or not!

My screen is all purple and green.

I think there is something wrong with a connection or with my screen. I can see everything clearly, it's just that the whole thing has like a purple hue / green hue that streaks and changes, kind of like an aurora you see in the sky, when I nudge the top part of my phone (screen part). I took a screenshot and I examined it on my computer, and it shows a perfect picture with no purple. Therefore it has to be my screen.
Do you guys know what's wrong with my phone, and how I can fix it? I am very hand with soldering and such.
Looks like this (not my phone, but the artefacts are identical:

Might be the ribbon cable between the screen and keyboard parts of the phone. Especially your description of the colors changing when you nudge it.
where can i purchase one?
And does anyone have a link of a DZ teardown?
EDIT:http://tjworld.net/blog/htc-desire-z-tear-down
But I still don't know where to find the replacement cable.
I have the exact same issue with my phone.
Here is the cable on Amazon
I'm just about to buy one myself.

and as for the T5 Torq screw? Any old hardware store?

Yup. Or you can get a kit with all the required tools online at eBay, Amazon and other places for less than $10 (just did a search for "phone tools" at both those websites, and got plenty of hits). I personally haven't taken apart my Z. But having taken apart other electronics (like iPods), its handy to have the specific tools (such as the plastic tool in the teardown guide) and can result in less/no damage to the casing.

Screen with lines multi colored!!

Hi, I have a big problem with my desire!
I lent several months my old desire a family member .. It has not been very careful and had no protective case he does not like it .. The phone was still working when I was handed.. However, the fully plastic housing was very scratched and small pines broken.
So i order a housing from ebay. I followed this video on youtube to disassemble the phone : http://www.youtube.com/watch?v=sXZqIjtFoAU&feature=relmfu
I assembled the phone later and I have a problem with the screen. I tried several times to reset the screen .. the screen is beautiful no scratched.
Here is my picture:

Help??
The screen is broken, you need to replace it.
Dunno but i would take it apart again and just make its all put back together properly, u never know, u coulda missed something or something not connected right.

Hi,
I disassemble several times and everything seems normal. Except that the GPS connector is broken because its a very thin wire .. but I do not think it is connected!
The glass do not have to be broken, but as i said before this looks like faulty lcd or the connector. However i would say it's fault lcd, 'cos connector would rather give you a light gray screen.
Looks like it gets 'bloated'...
This is strange because the screen is in good condition and the connector too as everything is connected. So you think it is the lcd has a problem .. I disassemble again yesterday and no improvements. However, the volume buttons on the connector that is connected to a part of the motherboard's detached. Possible to fix?
Screen doesn't need to be broken to be fault.
If it was me - i would say the screen is broken and i would replace it as it looks so. But i can't promise that's it, sorry.
I'll wait in case , thanks for your time!

Broken Battery Connector (solder pads)

So I successfully replaced the lcd on my optimus G...unfortunately I unknowingly broke the battery connector during the process (the female part soldered to the board).
Took me a while to realize what was going on, the phone was heating up and turning off randomly.
Anyway, it looks like the rightmost solder pad has lifted away from the board and the battery connector. Be REALLY careful when removing this thing people!
By chance does anyone here know where I might be able to jump this connection to? This solder pad seems to go nowhere - or at least not that I can see.
Thanks

hey u ever fix this issue? I have the same problem right now. Fixed the screen broke the battery connector lol.
I did not. Gave up and ended up getting a new board and giving it back to the owner. Wish I would have tested the new one before I gave it back. Perhaps there is a jumper we could have used.
Did you break the same pad?

[Q] No Bluetooth/Wifi after Charge board replacement

The charge port on my phone went bad and needed to be replaced. The replacement went smoothly but now it I have no bluetooth or wifi antenna. I get maybe 1 bar indicated if I am a few feet from a wifi hub and bluetooth isn't working at all. I thought it might be something to do with the new charge board so I replaced it again with the same results. If anything it might be even worse now. Any tips on what I should be looking for that is wrong?
Sounds like you broke one thing fixing another . If it's physical damage you need to go backwards and check all your steps and see what happened.
If software issue try reflashing modem.
Pp.
I found the problem and it, which is a simple one, The fix though I think is going to be difficult. A very, very small capacitor is missing from the board. I must have hit it during the charge board change. If I knew the value of the cap I could probably solder a new one on. I have no idea how to find that out though. Here is a picture of the missing part.

A lot of internet digging has turned up the spec on the missing cap-
Samsung part #2203-006665
0.0022NF,0.25PF,25V,C0G,0603, C-CER,CHIP
That particular number is out of stock everywhere but I was able to find an equivalent from DigiKey.com
Samsung #CL03C2R2BA3GNNC
Digi-Key #1276-1403-1-ND
I bought 10pcs @ 2 cents a piece.
Good luck with the soldering,
In case that doesn't work for you maybe this will work for you.
Pp. Lol
Soldered in the microscopic capacitor yesterday and phone is back to 100%!

Carlinkit CarPlay Ai Box disassembly?

Anyone ever open one of these up? Non-destructively, of course. With summer coming up I'd like to try to 3d print a new enclosure for it to improve heat dissipation and possibly pop some heatsinks on important bits. I'm assuming there are screws under the rubber pads on the bottom, but I don't have access to it right now and thought I'd see if anyone has opened one up before... Thanks!

As a follow up, small screw under each of the 4 pads on the bottom. Antennas are connected to top part of case via pogo pins.

Did you manage to creat 3d print to improve the cooling system? I have the same model EAU and i have big issue with overheating (91.8 °C was maximum) i have a lot of reboots... As someone answered above, the antennas are connected to the top cover using spring pins, so the back holds the front end in place to connect to the antennas. I was thinking that we could mount a 40mm fan on the back of the equipment, having a 3d printed case
