Hi guys,
First post but been reading the forums for a couple of months (excellent source to learn Android).
I bought a Dasaita PX5 headunit and installed it with no issues. Everything was great.
One day on my commute to work I had Waze navigation running and all of a sudden screen went completely blank.
Tried to reset and even though the lights blink in the touch buttons nothing happens.
Discussed with Dasaita support and they sent me a new core board.
I installed the new core board today but unit is still dead. Screen is completely blank.
Any suggestions?
Only had factory stock rom and never tried to flash a custom rom.
I’m desperate here. Bought the unit 8 weeks ago and have had it running for less than a week. Shipping of new core board took ages and I had to pay additional customs fee.
Really hope someone has a good idea
Sounds like the screen conked out. And/or connections between the motherboard and the screen.
What they should have done is sent you a new unit instead of a core board, because that unit ought to be under warranty.
Regardless, did you notice if the connectors going to the screen were loose or ajar? Did you reconnect them?
Did check screen connectors when I changed the core board. Everything was in place.
They now agreed to send me a new unit so now I can just wait. Hopefully the new unit will work with no hiccups.
In my case, The solder of the motherboard was melted and it was short-circuited.
Nothing was displayed on the LCD. I cold only see the touch key backlight.

This unit was sold by Dasaita (HA), And repaired by cleaning using a solder suction line.
The motherboard looks very ugly, but I only cleaned part B. You better consult a person with expert knowledge before doing it.

Yes I did. But if it fails, your unit will be a complete trash...
Hello friends,
I‘m new here but I have the same problem like the thread starter. Im from germania, so my english is not the best
My story :
Last year in august i ordered my Witson rv5336.
It all worked fine, but this monday nothing worked any more.
The screen is black, no sound no reaction to the touchscreen. Only the keys are lightning. Tried to do a hard reset, only the keys are blinking.
Witson, the manufacturer, said i need a new coreboard. But for me, it sounds like a dead screen?
What do you think?

I own a Droid 4 and recently dropped it, cracked the digitizer, and replaced it. Now my touch screen is only detecting these thin horizontal lines on the upper half of the screen. I'm wondering if it's possible that I screwed up the phone on disassembly/reassembly or if it's more likely that the new digitizer is defective.
Has anyone seen anything like this before?
Thanks,
Alex
P.S. The attachment is a screen shot of my phone running an app which detects points sent by the touch screen/digitizer and records them.

Bump
Firstly - please don't bump your own threads, and certainly not until at least 24 hours have passed.
Secondly - The reason for you not getting a reply is likely due to the fact that XDA is actually supposed to be a "Development" site, not a "Hardware" site
Thirdly - The likelihood is that you either;-
a) bought a cheap, eBay special digitiser which is not fully compatible
b) didn't get the connections right on install
c) broke something else inside the phone when you dropped it
Start off by taking it all apart again and rebuilding it, if that doesn't work then decide if you want to spend more money buying another digitiser or just ditch the phone and get a new one.
P.S. Why include a pointless poll for this thread?
P.P.S. Not sure why, but you have made two posts and XDA shows you as only making one. Strange.
That is classic yo, made my night. Well I was just checkin in here cause I couldn't find a more appropriate forum. I figured someone might know something, but yeh sorry bout the bumps. Although it did get you to respond, hopefully I didn't break something. I don't think so because everything on the phone works perfectly, I even fixed the little headset speaker. After much arm pulling I finally convinced the company to give me a refund, we'll see if a new one does the trick.

Attached is a picture of the motherboard.
I have made a circle on one part of it. As you can see, there is a blue thing to the right - before, there were 2 blue things next to eachother. But the left blue thing is now gone, I don't know where... But seems like it has fallen out somehow...
Is it possible to solder this together? Or do I need the blue thing there?
When trying to use the motherboard, everything works very well - EXCEPT the touch screen, I cannot do anything because the screen doesn't feel my fingers (nowhere on the screen). And no, I have no clue if this is the reason for the touch screen not to work, but that's my guess as it worked good before.
Any help would be much appreciated, I don't have much knowledge about soldering and so on, as you might already have understood from my description above...

I would highly suggest that you do not try soldering if you don't have any previous knowledge or experience. As for if the "blue thing" is needed or not I am unsure because I myself know little about what each piece does on the board. But as far as the touch screen issues goes, if the touch screen worked before the blue piece came of, it most likely has to do with it. If it didn't (or even if it did work before), try finding a second device that is the same as yours (or if its cheap and you can afford it order a new lcd/digitizer for it) and try connecting it to that motherboard and see if it works, if so problem fixed, if not, you may be able to take i to a phone repair place and have it fixed, though most times getting a new motherboard/device would be cheaper.

Thanks for the reply.. I have actually ordered two other "broken" phones, so I will receive them in a week or something... And I will do exactly what you suggested, to try another motherboard and see if it is a problem with the screen or motherboard. I am very sure it is the motherboard though, because the lcd and digitizer worked great just before I discovered that.
Would still appreciate answers regarding soldering this, if that is possible or not.
Solder motherboard, possible?

It seems like your missing a resistor . you can simply measure the values on the existing component and order the same value on digikey. let me know if you need help with soldering

Ah, a resistor! Not easy to know when you have no clue what it is...
How do I measure the values on the existing component? I don't really think I need any help with soldering, but pretty much everything before that... Haha
Thanks!
Hi,
I originally posted here:
http://forum.xda-developers.com/google-nexus-5/help/attempted-repair-n5-usb-port-phone-t3157969
But my issue has somewhat changed. I realised that the phone was still working, and i could see stuff on the blank screen if i shined a flash light at the screen. This led me to beleive it was the backlight that was broke.
I investigated replacement screens and it seems that there a lot of cheap replica screens out there that have their own issues, and rather than pay full price for a legitimate LG part (around £95) I decided to buy a second hand faulty N5 from eBay that had a working screen (£50). The one I purchased had an issue with its mic, and the screen works perfectly fine.
I placed my motherboard into this phone from ebay, but it became apparent that the same issue was happening. The backlight wasnt working in this other phone.
I placed the motherboard from the phone I bought off ebay and it worked with the screen in my own phone!
So the problem seems to be isolated to this part:

I didnt think the backlight would have anything to do with this, however its the only part I have swapped around. :/
Anyone have any ideas?
Thanks
Same issue?

Was your problem like this https://www.youtube.com/watch?v=Jq0buYBFdKc ?
I am having this issue, the brightness is very low and still at maximum, the image is poor. I don't know if buying a new mainboard or a display
Thanks!
Hi there, just thought I would share this with you and ask what you think.
So, I have a Moto G 3rd (bought it a month ago), I quite liked it and was a good upgrade from my original Moto G. However, I never expected it to be so fragile. After one small fall (like 30 cm) my screen seems to be completely messed. I mean the display, as outside the phone is just fine, no cracks or anything, and it was the first time I dropped it. Here's a picture:

}
This is really disapointing, and I'm in complete shock, as probably warranty won't cover it and the phone was a major investment for me. Has any of you had a similar experience? Is the moto G not as resistant has it once was? The original one could take a LOT of damage, and it just dying like this on me breaks my heart.
So, what should I do? I contacted Motorola on the website and after a long talk they basically just told me to go to the store where I bought it, which I'll do thursday (it's far from where I live), but I fear they won't offer help. If they don't, is there a way to still send it to Motorola and pay for the repairs? I've tried china replacements on other phones and was never quite satisfied, and this is a new phone :/
Thanks for reading, needed to share my pain!
That's exactly what happened to my previous phone (samsung galaxy s3 neo). Screen was ok, also because it was protected by a tempered glass, but the lcd broke and only showed a few purple lines.
Unfortunately, the outside screen spare was quite cheap (30 euros) while the lcd repair was 120 euros, so I decided to buy the moto. A bumper should protect from this kind of accident.
I'm afraid it's bad news.
Hi guys, just here for a quick update.
I went back to the store and since the device was in very good shape they sent it to warranty and said it could go off has a gpu fault.
I'll update when I, hopefully, get it back!

Great news, let's keep finger crossed and hope they can fix it for free.
Hi again!
Just here to tell you guys I got my phone back and the repair was covered by warranty! Hope my story helps if anyone runs into similar trouble. It was fairly quick too! (2 weeks)
Bear in mind my phone only had 1 month and was in really good shape (no scratches).

I'm going to say you probably dropped it and it broke the touch screen. I had a similar issue where I dropped my A53 from 3 feet, no visible damage at all to the case, screen protector or phone at all, but the battery would drain over 20% overnight just sitting on my nightstand and Wi-Fi was broken. I tried resetting, nothing worked.
Your next step is to register your phone on the Samsung website, request a repair, and they will send you a prepaid shipping box to send it out to their repair center, and you should get it back in about a week.
The A53 isn't durable at all. It's a nice phone, just don't drop it from more than 18 inches.

Why didn't you send it to Samsung? It's under warranty.
