[Q] Semi-damaged XDA Orbit

Hi everyone,
It is almost 2 weeks my XDA Orbit is not working properly. The first time it hanged-up during a call and afterwards it took me several resets to bring it back. During the system load the screen was changing colors and freezing, sometimes completely white, sometimes with some colorful stripes, sometimes solid violet. After several reboots I couldn't turn it on at all. I took it to local service, where they told me that the problem is with boot loader and fixed it. I took it back and have the same experience. I have flashed it with original ROM, both from PC or SD card, but the same problem exist. I am assuming that the issue is in a hardware defect. I know that it is the time to get rid of this PDA and get a new one.
Anyway... Is there a tool available for testing HTC hardware (CPU, flash)???

possibility the battery gone or the lcd.
buy a new battery, theyre only cheep so start there..
leave it off while charging, green led when done.
if its not your battery, i think its your lcd..
best to open the device and check your lcd is connected properly..

Opened my Orbit recently, the connector is in place. I would assume that the issue is more in battery then LCD. The battery surface is lofted.
Assuming that it's a battery issue - should the same happen if the device is always connected to external power supply?

...
LOL
get a new battery dude..
dont turn the device on untill the new battery is fully charged.
a simple fix hopefully..

Nexus has grainy screen

Hey all; I got a Nexus 7 this past December and everything was working great until yesterday.
I took it out of my school bag and when I pressed the wake button this happened:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now whenever I wake up my Nexus the same thing happens. Sometimes it goes back to normal after a few seconds, but it continually freezes or has random slow downs.
I reset the device and erased all my data and whatnot, but still the same has happened.
Any suggestions?

What ROM are you running, stock or custom? Try reflashing a ROM (let us know if you aren't familiar with that) in case something's corrupted. Hopefully it isn't something with hardware.

This should be a hardware failure.Take it to the service.

@Pandae: Everything was stock. @GeoVali99: Correct-o, sir!
Ended up being a hardware issue so I'm getting it repaired.
I appreciate the words though!

Hi!
I've got the same problem.
Can someone tell me how to fix that Problem by my self?
I have no guaranty left...
Thanks!

Not a big deal. The LCD is fine. What happened in my case when I got exactly the same screen is that the amber ribbon (LCD to motherboard) seated wrong, and I bent a pin on the motherboard connector out of shape. You open the back cover and reseat it, but make sure you do not damage the pins. In other words do it very gently, do not force anything, and monitor it all with the help of a magnifying glass.

[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%!

How can I make the head unit forget my Android account and Bluetooth pairings?

I had a problem with my head unit and wound up purchasing a new one. Between order and delivery dates, my original unit started working again and would like to sell it. Is there a way to purge it of all personal data without performing a complete reset?
On a side note; who wants a nine-month-old head unit?

Can you put some photos and a complete description of your HU (MCU version, etc.), please?

I have the dual-core 800x480 version of this;

Mine is a Joying unit.
It has worked fine for the past several months, but developed an issue where the screen would flash, pixels would be in the wrong spots, and then go dark. Despite all that, the touch screen part of it worked fine (as long as I knew where to press, I could get it to work). After much discussion with Pumpkin, I removed and installed the ribbons to the screen. This did not fix the problem right away, but the unit is working fine now thanks to the FM Principle. My skills have reached their very limited limit and I fear the problem will manifest again.
I personally think there is an issue with a connector to a ribbon or else the screen itself has problems and that someone with a little bit of knowledge can make this 100% again. If I hadn't jumped on a holiday sale, I would keep it and be happy. But I did jump on that sale and would rather recoup some of my money than install the old unit in another vehicle or give it to my cousin to enhance his electronics education.

Hmm. Wish I saw that before I did a full reboot.
Thank you. I will keep it in mind for next time.

Digitizer, different REV?

Hello everyone!
So, here's the story.
G3 put on subwoofer, falls down, gorilla glass screen cracked. Full working but cracked. So, new display+digitizer+frame, all already attached to itself.
From here: http://www.aliexpress.com/item/For-...el-frame-Full-Assembly-Tools/32440683620.html
Loot at the photos and the digitizer circuit. And then look at this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Are you looking? The above is my old screen and the circuit of digitizer is the same as on pictures from link above. The bottom screen is the new one that came to me from China. Do you see difference?
Well... Though I like new things... Screen worked. I noticed an input lag, when I was fast typing on keyboard. When I typed a word really fast, the lag occurred and then a the word was fast written. Not important.
But after a few hours (like 16) digitizer stopped working at all. From its own. I just pulled the phone out of my pocket and couldn't unlock the screen. Touch was gone.
You, dear reader, you are smart. So you think it's probably a bad resistor like here: https://www.youtube.com/watch?v=t_9QHXZnZ1g
No it isn't. I tried my old cracked screen and everything works there.
Question:
Do you think it was just a false component on circuit? It happened with this new (I just think it's newer) circuit, but also could happen on an old one. I just was unlucky.
Or is this new digitizer designed for some new versions of G3 phones? Mine has approximately 3 years.
When I'm gonna buy a new screen, should I be looking for digitizer as on my old screen? Is it even possible to buy them?
Sorry I made it so long. I know no one likes reading
