Question Out of Warranty Joying Head Unit Repair Vendors? - FYT Android Head Units

Anyone know of vendors I can contact to get an estimate/quote to repair my Joying Android head unit?
My credit card company has insurance which "extends" the original manufacturer's warranty, but they are asking for a formal "repair" estimate; they won't accept evidence of the cost of replacing the entire unit.
It's a pretty niche device so wondering if anyone knows vendors who will perform Joying electronic/board repair? Location doesn't matter as it can be shipped.
I already tried contacting Joying themselves, and awaiting a response, but not sure that they even offer this type of service outside of warranty.
Thanks!

What's wrong with it? What are the symptoms?
In any case, try one of those cell phone repair shops/chains. I remember quite a while ago that they repaired game consoles too.

It sometimes powers off then back on, and I think the bluetooth module and SIM card module need replacing.
I reached out to a couple of those types of shops locally but I think this Joying unit is pretty niche so they don't service it.

Is it possible it's a power supply issue? Were the wires crimped together or soldered together? Maybe take it out and hook it up to a power supply on your kitchen table or desk for a while to see if it happens again.

Logic Board Replacement

I've done some things I shouldn't with my brand new phone (such as buying a generic car charger) and so happened that my phone is Dead.
I have to replace my phone's logic board, and I live in Brazil. The only place I found that could do such thing here will charge me the modest amount of $600 USD. Well, I might just throw it out of the window and buy a brand new Touch Diamond with that money. But before it comes to that, I would like to know if anyone in the US or Spain (places where I can ask friends to buy the board and ship it to me) knows where I can buy a new TC Logic Board, and if so, for how much? Online parts shop maybe?
Maybe try this company. As far as I know they are doing very simille things.

Help on identifying problem

Hi guys,
My htc fell in water, but I have dried it up. Now when I press the power key, the screen does not turn on. Then, when I press it again to supposedly off the screen, the screen turns on and off in 1second. So I can catch a glimpse of the lockscreen. So I was wondering, does anyone know why this is happening?
Is this a problem I can fix myself or should I bring it to a repair shop?
Any recommendation on a repair shop besides HTC. HTC did not even bother to look at my phone, they just saw the water indicator and said it would be $300-$500, which in fact, I know that it would not be that much.
So if anyone could help me, thanks.
I'll upload a youtube video so you guys can get a better understanding.

Had the same accident on my wifes last Nokia, couldnt repair it myself and brought it to a repair shop. They told me to throw it away because the water sensor inside the phone reported the accident audn a repair would be as expensive a an equal ne phone. sorry mate, dont hope too much ...
I guess I shall just get a new phone, like an evo 3d or something. Thanks anyway
Or they can replace the parts that's been damaged. But i'm not sure if the repair costs more than buying a new phone.
I believes LCD internal circuit detect short and turns of lcd to prevent damage.
LCD may still have water inside or main board may have been damaged.
It is impossible to guess so repair tech must use parts from good phone and swap one by one to bad phone until bad part is found.
Most repair shop will not have ability to do this so they will charge minimum $200 ( average cost for them to buy phone) or they will assume LCD is defective and quote about $150. ( their charge for LCD replacement)
HTC just charges you phone refurb charge ( for customer not their cost)
I recommend sell on eBay for $150 and buy new(used phone) on Craigslist($200-$250).
I assume since you are asking this question you don't do many or any repair...if this is true...I highly suggest you keep it that way to prevent accidental and uneccesary damage
PM me and I can assist with repair/replacement

I was kinda hoping to fix it, but I guess I should go to HTC and ask them for an exact amount of price needed to fix this phone.
I doubt there's anymore water in the phone cause I have dried it for 3days in rice and even hair dryed it.

[Q] replace motherboard or swap screens?

Ok, ive given up hope of un bricking my tf300, and probably will never buy another asus product after this. My question is, should i replace the motherboard in mine, or put my screen and digitizer in another tab that i can buy for about the same price as a motherboard? Which would be the easier swap, and can someone like me without any special skills even accomplish this kind of thing? Oh yea thank u all for ur help in the past!!
Either is an easy fix, but I stole the digi/lcd combo and the TS board from my TWRP bricked 16GB to replace the cracked digi on a recently acquired 32GB model. I should be able to recoup some more from the non-logic board parts remaining, enough to more than make sense over buying a logic board alone. The battery, TS board, and good LCD alone might take care of it. If not, then maybe including all the little parts and cables inside will. Even if it is more effort to post and sell all that stuff, it should add up to more than selling a parts tablet with a broken digi and bricked logic board.
But then, I've had many tablets apart, and I'm decent at repairing them. Someone who has never had one apart might find either path daunting.
If doing the repairs yourself isn't a good option, you could always take the tablets to a cell phone repair shop, assuming there's one near you. Replacing the screen on a tablet is similar enough to a smartphone that they shouldn't have any problems. There's also a chance that they fix tablets anyway since they're kind of like big smartphones in the way they're assembled. And since you have your own parts, the repairs shouldn't be too expensive.

[Q] LG refuses to repair; what should I do?

My device recently survived quite the impact, the screen got shattered, top right edge got deformed a little and then the ON/screenlock button stopped working the next day, but otherwise the phone was fully functional. So I sent it back to LG for repairs and the next week I get it back in the same condition, with a note saying it's not repairable/board cracked. I called them up, and got an image of the motherboard showing no cracks whatsoever, yet they still didn't want to re evaluate their conclusion when I created a new RA. When I got the phone back the battery was dead and even though I charge it I cant turn it on, until the button is replaced. LG suggested I contact Google for repairs, Google said I should contact LG. These people are helpless, they don't know anything. I could do the repairs myself, but I can find all the required parts online. Can I get some suggestions on my next step?
"Thank you for contacting LG Customer Service.
We are sorry to hear about the problem you are experiencing with your LG device, however, your phone has already been inspected by our technitians at our repair facility and, unfortunately it has been determined that it is not repairable.
We recommend you contact your carrier for any replacement possibnility."
not much to do but to repair it yourself if you want then, or maybe look for one on swappa?
for parts http://www.etradesupply.com/lg/android-models/lg-nexus-5.html or ebay
btw it looks like you need this http://www.etradesupply.com/lg-nexus-5-lcd-screen-and-digitizer-assembly-with-frame.html
Screen and battery are no problem, i could replace them any day. The power button (blue circle in the pic) doesn't work, if that's the issue, I would need to replace it, but I can't find any replacements. I actually spotted a tiny crack on the board (red circles). Ugh. Would i have to replace the whole thing?
Maybe its best to sell it for parts and buy a new one, that phone looks allmost like a total-loss. Maybe some of the internals are damaged also and total repair would be too expensive.

I have issues with the power button too because mine get stuck lot of times and it's verry annoying. I've contacted LG service center but they said that because it is soldered to the mainboard the only option to repair is to change to mainboard. I'm shocked . I haven't got warranty here because I bought it on Play Store in Canada and I'm living in Europe.
Btw I've started to research this issue and the parts and it seems these switches are the same as Samsung uses in their new galaxy phones. There are tons of pieces on ebay from it. But changing it is hard. You need a good heat gun which is able to point the heat to a small area and you have to heat the switch only. If you heat any other parts, then you phone is dead...

But I'm not hundred percent sure that these are good switches for us, they just look the same :/

I've done the repair on a Galaxy S3 using the part from Ebay. Let me tell you now that it is a pain in the ass if you don't have good micro-soldering skills. I don't, lol, but my father does and he got it done for me. Be warned, you will mess up the board if you don't know what you're doing, but it can be done. Maybe find someone local who can do the swap for you.
buy a new one, cause this one is a dissaster! keep it for repairing parts...

Hi guys

I recently started learning how to repair smart devices about half a year ago and I love tinkering around with different issues. Sometimes I would buy or auction devices off eBay and tinker with it. But sometimes I have come across a water damaged device and I was wondering does other components such as camera, flex cables, and other components other than the motherboard still work? Does using a multimeter continuity help finding out if it still work? Because right now I am building a website where I want to try to sell parts and components at a discount price. Someone please help answer! Much appreciated.!
