me and my universal had an accident/coaxial cable ?

hi,
some time ago had car accident and my universal was my sat nav at that point. since it was a serious thing (my car is scraped in germany now ) my uni got demaged. i lost battery and back cocer but all the rest looked OK untis i switched it on. i mean when it does switch on the screen is white and that is all it does. i think the rest is ok cos i can hear some voices made by my uni and the leds are working.
i did some research and it maybe due to the coaxial cable. so i took my uni apart , localized the cable but it seems ok..i mean how do i know if it is its fault ?? if anybady gat a spare one or other sugestions then i am always willing to hear some. the cable costs around 70 GBP so i am not sure if i want to heve a go

Are you sure?
Coaxial Cable? What would it be doing inside a cellphone?
Those are used to transmit TV signals, since they are shielded against radio-frequency interference. Plus they are about as thick as the Uni's base, and very rigid.
Are you sure you read it right?(No offense meant...)

hi, thank you for your wisdom mate but i am sure. try searching "coaxial cable" and you will learn something new....
can someone tell me if the white screen of my uni is caused by this cable or there may be other cause of this problem. after i took it apart and took out the cable it looks as if it is OK. i mean it is not broken or snatched...
advice please !

Best to post 'facts' when you're sure your right.

I've seen posts about the white screen before on here. It seems to happen when people drop them too. Since it has received a strong 'shock' in the car accident, I'd look up posts on dropped phones. Try a search on stuff like 'dopped' + 'white screen'. Hope you can fix it. There are also posts about very cheap repairs being done at local phone repair centers.
Good luck.
Try these for starters - the first one asks a guy who dropped his phone if he can still see inside it on active sync - if so it looks like a screen connector problem:

All right, all right, mea culpa...
Up till now, I thought that was what coaxial cable meant. I didn't know the screen connector was called coaxial too.
So, once again, sorry for posting without knowing...

hi, i am happy now - i took my uni all apart then put it all together acording to mannual and what i have read after c.a hour of strugling with uni i managed to put the batter in and switch the uni on and ...it strarts up normally , no white screen ...everything seems to be alright now. i think it was caused by lose contection of cables and fortunately not the 70 quid coaxial cable itself ...

Great news! I bet you're happy. I would be. It seems that strong shocks like being dropped (or being in a car crash mounted on the dashboard) can shock the thing so that the cables become slightly disconnected. Well done for fixing it.
Reading this forum lets me know what I'm in for when I drop mine... It is bound to happen sooner or later. At the moment, I'm keeping a very tight grip on it.

Front Camera Board Shorting out!

hay i recently dismantled my HERM100 to figure out why my battery life went to hell, and where most of the heat in the front was being generated, as it turns out i have a short somewhere in my Front camera board, and need a replacement.
does anyone know (preferably in australia) where i can get the component, other than on ebay, or is anyone willing to sell a "bricked" hermies so i can just swap the mainboards round and go?
this also seems to be messing my camera functions, and front led's have gone dull, other than that its working fine.
but if anyone has known this to be a software issue in the past, this fault only became apprent after i updated the boot loader, and software for the wi-fi/GSM and OS, or it was just going to do it at that verry moment becuse murphy hates me!
on another note is there a copy of windows mobile 6 that will work with PDA's as reasion being i recently handed over my old HP-R17 somthing or rather, to a friend who needed one, as fortune follows he like my self hates the ok button that dosent close squat, but minimises things and i am feeling that the taskmanager designed for WM6 wont work on a pda with WM5 that too and he would prefer to update, just wondering if anyone has tried this before!?
ps ... bump!

FIXED
i managed to fix it, it was a shorted capacitor on the camera board connected to U2, i think it was U2, but it only was connected to the LED's this cap is connected to the Ground and positive going rail and is mostly a filter cap, it was a little burnt and fell off easly after which all worked cool again and no problems with either the front camera or the main camera.
this thing was so small it was only visable as a faulty component under a high power magnification

HP hw6515a boots up but the screen is all white! Please help w/ my 6515

I took apart one my hw6515a smartphones and gave the faceplate to my sister's boyfriend who paints at a body shop. He painted it blue to match my truck although i believe the paint he used was for a 2000 Acura. Regardless it looks awesome, however that is all it does. It boots up and you can tell that because of the sound and you can blindly make calls. However as the title of this thread reads the screen is all white from the moment you turn it on. It was working before I disassembled it. I have done computer repair for a living for the past 10 years and I thought I was careful with the motherboard and the other PCB. Anyone with experience with this please reply, thanks! Not sure if I somehow damaged the screen or I am hoping there is some little nuance I overlooked during reassembly. It was kind of a pain in the butt trying to connect the screens ZIF connector because it and the speaker wires are short and so they have to be reinserted while this case is almost all the way closed.
A little about me + if you want to by the HP smart phones: I have known of xda-developers.com for years but haven’t had the time to participate in the community up until recently. Two weeks ago I decided to try out wm65 and it it awesome! However flashlite 3.1 was working with all browsers on my original Fuze firmware and now it is not, anyway I am ranting, I need to go to the proper post for that...
I have a (3) hw6515a's. Actually I have 4 but two of them are broke and together can make 1 full phone. If someone wants to make an offer to buy them with all the goodies that originally came with them feel free! I love HTC and currently use a Fuze and a Tilt (aka Raphael) both running WM6.5 . I just sold my 8525's and have had earlier HTC's as well. OK enough confessing of my love for HTC. I have taken a picture of the blue HP using my Fuze's camera in case anyone is interested in making an offer and it is attached below. The HP is a nice lightweight smartphone with GPS built in however the 240 x 240 px screen can prevent you from using some apps the way you want although i downloaded a fix off that allows you to run apps designed for 320 x 240 px. OK I am gone, sorry for the blathering; my mind has not been working properly the last few days.

Sounds like a connection to the screen is not right.

there is only 1 connection for the monitor
That connection is a small zif connector. I have tried reconnecting it multiple times.

[REF] GT-I9300 Service Manual

Here is the Samsung Galaxy S3 (GT-I9300) Service Manual.
Please take a moment to read the notes and issues about this manual in this post.
For some reason Google didn't pick up that post, so I had to re-post here...
Now, if you are brave and happen to have a GT-I9300, you can still help us by posting some
internal pictures, to verify some issues in the manual. If they are good,
some of them will eventually become part of the SGS3 Hack-Pack.
Thanks and Enjoy!

I will be opening up the phone in the next few days due to me managing to damage the sim card holder section(not holding sim card) So at present i have got somthing putting pressure to keep sim card in place. I have a new sim card holder on order so when it arrives i will pull phone apart and take some pictures.
If you have any advice for me before attempting this please let me know via pm

Do you have any experience in this kind of electronics? I mean, are you planning to replace and solder the SIM card holder by yourself?
If you have not done this type of soldering before, I do not recommend it.
If you do decide to do it on your own, make sure:
You are working on a clean workspace
You are well grounded and not wearing wool clothes mixed with synthetic materials to avoid any ESD.
Have the right tools for the job.(Temp controlled SMD soldering iron + flux and acid-free lead-free SMD solder etc.)
A very steady hand with good eyes!
As for the pictures, keep the environment as bright as possible, preferably daylight. Try to keep your PCB on a bright or neutral background. (Bright cardboard is usually good.) Inspect your pictures and make sure you can read the text on the smallest chips. (The big ones we already know about, its the smaller ones that are difficult to navigate around.) Make sure the pictures are well focused.
Good Luck!

From looking at the pictures I was hoping I don't have to solder the sim card slot in. It looks easily replaceable as it looks like it's just a connector and not soldered

Replaced the sim holder. My camera wasn't good enough to get focus of the smaller chips however it is very very easy to take phone apart. And I guess Samsung are expecting issues with sim slot so they have fixed it using one screw and connected to board using a pull off connecter.
Just in case anyone else is interested the sim holder/sd holder cost me £20, delivered.

amazing !!!

Hi guys,
Here is my contribution to da community, hope so it helps.
h t t p s : / / docs . google . com/open?id=0B9lrf7AWQW7ETjRZTkFXb1luN0E
On image 20120616_150200.jpg you can see the region jumpers. The images are of a live demo unit - everything works besides the GSM/3G data. Haven't tested to see if the NFC is working.
The real unit has some more antenna connector. The demo one does not have PBA /printed board antenna/ the ANT102 and ANT103 as well as the capacitors and the coils u may seen them market in red cycles (ANT102, ANT103, C102, C191, L103, L102) there is no room on the MOBO for C192 /or at least I can't find its place/.
Thanks.

^^ Here is the link for above! (Thanks!)

Hi again,
I can confirm that the NFC is working on the live demo unites. According to the original S3 user manual the NFC antennas are build into the battery back.
I still can't figure out what is the "W2" antenna connector for. The Live demo unit has no connector soldered to the motherboard and also lacks the small PCB antenna with the white coaxial cable. Some ppl claim that the W2 is for WiFi antenna, but it is not, because I got great WiFi connectivity tho the lack of such PCB antenna. I can only confirm the WiFi working fine, under "G" type of WiFi networks. The openWRT firmware of my current router has known bug and I can't bring up "N" standard in air, to check if the PCB antenna is for "N" type of WiFi networks.
I also did some testing to see if the PCB is for GLONASS or GPS, and it seams that this PCB antenna with the white coaxial cable is not for any of these services. That's why I think it might be for wifi "N" or 3G data/networks. Donno if the 802.11n requires a separate antenna.

^^ Please post a link to a specific image, that clearly show the connector(s) you're talking about.

Hi I have a live demo unit to, so I think I can help about this =).
I can't show you the mainboard back because I' m new user... xD
I don't really know what you mean with NFC (sorry, I'm not really good with english)
But
W1 is a GSM external antenna conection
W2 is a wifi external antenna conection
And the white wired antenna is for wifi to.
After thinking a lot, if you conect an antenna to the GSM antenna conection (external or the internal lacked in Demo unit) you probably can't use phone function.
That function probably was crippled by software or because demo units don´t have imei maybe o.o.
The only thing I need to try is to connect a microsim to the phone

No one has any insights ???

Samsung galaxy S3 i747
i have a Galaxy S3 SGH-i747m that has been water damaged and given to me so i could try and fix it. I can take pretty much any pictures you want, have openned the phone a couple times now to try and clean it up.
My problem is that the works well, it starts up, unlock the screen, plays sound...but the screen is off. Now at first when i was "playing" with it the screen would flicker on and off to show me the battery charging logo when it was plugged in. I've cleaned the phone and all flex connectors with some products. the phone still turns on and works but my screen is off. It detects the touch since i can unlock the screen ( it plays the water sound when i slide my finger on the screen) and speaker works when i boot it up (little booting sounds).
I was thinking there might be a small fuse on board for the screen backlight and that could be blown. I was also thinking my battery might be damaged and is not giving the phone the right voltage to the right connectors or something so i have ordered a new battery on ebay (under 4$) and am waiting for it.
Anyone has an idea to some specific things i should be looking for ? only thing haven't disassemble is the digitizer from the framebecause doing so would surely break the glass. It bums me up a bit since there are some electronics behind the frame that could have been damaged by the water that i couldn't see.

check if you can see anything on the screen, use some extra light, torch for example.
if so - then its more likely that the LEDs in the display panel are damaged, since it flickered, as you said. also could be the driver circuit for backlight. Clean connectors for display panel, use magnifier, or better microscope to check for corrosion. use IPA to clean or scrape off the corrosion.
also - maybe this is not the right place to discuss this.

I don't have he white antenna coaxial cable neigh the PCB antenna board that this cable is connected to but I have WiFi.
Could it be for WiFi N(150Mbps)?

I have identical symptoms with my i9300.
1. Water damaged
2. Dried in a can of rice etc over several days
3. Cleaned under sim card, lots of debris there, looked scorched, I cleaned with alcohol and a brush in an ESD protected environment.
4. Re assembled, the display briefly flashed on, and showed the expected "Battery is low, an d No Sim Card" then powered off.
5. Now after charging the battery and emplacing my sim card, I hear the proper musical tones when the phone boots but the screen doesn't light.
Where you able to get the screen working?
I am going to try a more throughal cleaning and I will try viewing the LCD under a more power full light.
I too worry that just getting the LCD screen replaced might not work; the screen may be fine but the mother board LCD power supply might be at fault...
I will keep you posted and keep an eye on this forum to find out how to fix this.

This thread has served its main purpose.

SM-G900T snapdragon to Android streaming box? Using internal video output

Ok, so i have my Galaxy S5 tmobile that ive been playing with recently. awhile ago i tried to replace the rear facing camera, and the loudspeaker. unfortunatly when removing the screen, the digitizer was damaged. oled was working great. i would just use a bt mouse to navigate. well last night i pulled the phone apart to compare the amoled connection to that of a S7. just to see if i could throw the S5 screen onto my broken S7 to attempt to setup screen mirroring to my tv and be able to use it with a keyboard and mouse for general streaming.
I left the screws out of the midframe assembly of the S5 and it fell off the table after being reasembled. (love when the pets get into my workshop)
anyway, it was just enough to crack the very corner of the OLED and now there is no functionality to the screen.
ive been thinking about trying something that i just havent seen before, and cant find any information on at all.
There has got to be a way to take the ribbon cable from the S5 screen with the connector and splice/solder into some kind of digital video output. also the audio to the loudspeaker adjusted to low-line and connected alongside the digital video to make a single digital A/V output.
Basically i want to have my BT keyboard and mouse and be able to have it outputting video to either a Moniter, tv, wireless adapter of some sort. i would leave the OS pretty much the same minus alot of needless software at that point, and be able to turn essentially any tv with HDMI or digital video in, into an android smart tv..
i have arduino uno kits and Abillion cables of all sorts.
if anyone has any insght to the format of video coming from the OLED connector, or a pinout , any information that would help me get the ball rolling on this. i would be extremely grateful.

Don't like MHL adapters for some reason?

They are nice and all. But that would mean I would have to spend money on something to make it work... Also mhl adapters take their own power supply at 5.0v, which means it would have to be plugged in somewhere during its use. Which I had planned on just using a couple 8000 mAh lithium batteries wired in parallel to power the phone at 3.7v. Getting me somewhere between 6 to 8 days of heavy usage before a recharge. And would make it much more portable.. Maybe even construct a small enclosure with a fan out of one of my CCTV cameras. Even if I had to convert the video and audio signals using a microprocessor, I wouldn't have to spend a dime doing the entire project if it works the way Im imagining it too. One of my main objectives with this project is to use parts from old equipment that I already have.
This is more about doing something creative and new with old Galaxy phones that have no other practical use.
Yes I could order an android box off amazon for less than 20$ and do what everyone else did to stream...
Yes I could order an mhl cable and set it up that way....
Yes I could put a new display assembly on it and use it for dev....
But if everyone thought like that, android wouldn't have existed in the first place.
