A Fried Kaiser

I managed to fry my kaisers circuits by plugging a 4 AMP car charger into the USB power port.
It only took one second, i smelled the smoke and instantly unplugged the cable, but it was too late.
Surprisingly the device was still powered and functioning, so i didn't freak out. The battery was already dead. after around 30 seconds it died again, i walked back home and tried charging it with mains adapter with no luck.
Next morning, i took my handset to a local electronics repair shop to check it, and i told them the story. they called me back and said the motherboard needs to be replaced. and it would cost me around $470. (and its not covered by manufacturers warranty. ouch!!)
After hours of cursing and smashing my head into the steering wheel, i thought i'll pick it back and try something my self.
the part where the device stayed on even after the smoke came out led me to believe that the board is still fine. and that only the charging port got fried.
the problem is, I don't have a desk charger to charge my battery and test my theory, a disassembly guide would also be very helpful.
if the main mother board was really fried, is there any place that i can buy it from? i did some goggling around with no luck.Anything cheaper than what these guys are asking for would be great, i have a feeling they are trying to rip me off.
If any of you guys can help me out, id be grateful.

I have a brand new AT&T Tilt ( kaiserII HTC8925) for sale i can sell to you for $375.00 New In the box never been used. PM me if interested.

Sorry I can't help in this matter, but I thought i would post this here rather than start a whole new thread.
I have heard lots of horror stories of in-car chargers frying kaisers. Has anyone got an in-car charger that works?

Order one that is made for the Kaiser...a lot of people are trying to use old chargers just cause the tip is the same.
I got my stuff from PocketSolutions.com

Car chargers that work for the 8525 should work fine for the 8925. It just can't do that "boost" charging feature the Tilt supposedly has.

That one won't damage the Kaiser, but it has only half the mA of the proper one. This can sometimes cause problems if the charge level of the battery is very low. For charging from time to time and when battery isn't near empty you will be ok.
Mike

well a quick tip would probably be checking the fuze on your charger, anything below an amp wouldnt do much damage. -.-;
4 amps fried my tilts motherboard, so watch out guys
still looking for a service manual, now that my phone is dead, i want to dissect it,

I'm using a cheapy chinese one made for an Imate Jam if that helps.

the part of the board responsible for charging is probably what went up in smoke - you probably smelt (smelled?) resistors/capacitors overheating/melting - they said a total mobo replace as that circuitry is probably all on the same board - sure you might be able to replace it yourself but i dunno - might be a bit of a mega mission what with all these micro components around on these sorts of device

Yep, these devices now have multilayer boards that make it virtually impossible to do a bit of home soldering/component replacement on.
Bring back the days of my youth when we had valves (tubes in US I believe), they were nice - and kept your hands warm as you soldered away in a freezing garage

Cracked Open
I opened up the case and unscrewed my way to the burnt part of the board.
thanks to mike and the manual he posted on some other fourm

Okay now i can at least see where the damage is.
Still stubborn that i am, I did not believe that this IC killed the entire mobo, so i invested in a desk charger for the battery and charged it up fully.
I just tested it now and to my surprise it WORKED!!
http://img211.imageshack.us/img211/5070/ks5vj6.jpg
Of course, my joy ride did not last for long as the device started heating up. I switched it back off once i felt the abnormal amount of heat generated.
I tried it again after it cooled down. This time I kept it for around three mins, and again it heated up, at the end of, it just shut it self off. (still heating up).
After that scary little experiment i learned few things:
1- The device motherboard is alive, there is no need to replace the entire board.
2- The burnt IC is probably meant to control the usb port and the power, therefore my usb port is useless at this stage.
3- charging the battery externally wont help much without resolving the heat issue.
I tried to look up diagrams for the devices board and the only thing i could found is this:
http://www.cdmatech.com/download_library/pdf/diagram_msm7200_cs.pdf
which is useless.
Any help would be much appreciated..
cheers

Can anyone help me with this?

the chip burnt shown in the picture above needs to be replaced on my tytnz mobo.
can anyone give me more details about it or where can i find a replacement, all i could read on it is the (QRA) part, if anyone has a tytn II could you have a closer look, grab me a serial number maybe.

mini micro USB is defect (battery will not charged)

Hello,
unfortunately, my micro USB connector is broken.
The battery will not charged.
Is there an instruction how can I change the mini micro USB or is there another possibility.
greets uzzoo

You can buy a seperate charger that charges the battery out of the phone, its expensive to have the micro USB port swopped out - unless you are to the job your self :

An external charger I ordered mine.
Would like to change the USB port itself, there is a tutorial somewhere as I ran to get the board?

The simple fact that you are asking for a tutorial means that you will not be able to do this job. It requires removing and replacing the actual port from the motherboard which requires some precision soldering. Send it away for repair if you wish it to be fixed.

That's a bit presumptuous! The OP might well be confident with soldering and internal electronics and by the sound of his post is (possibly! ) looking for a diagram of the board itself.
It is indeed a tricky job but the guys in the repair centre started somewhere too. For all we know the OP might even consider his HD2 expandable for such a learning experience!
Good luck OP. And you can't go wrong with an external battery charger, couple of £s from eBay. Although ive found they tend to only charge to 99% and lose the first 10% quicker than if you'd charged via the phone.

Had thought that someone has already changed the USB beech.
Just wanted some advice.

I had this exact problem a few months ago. If you find a very skilled solderer... i.e. someone competent solder smd devices then you can re-solder the usb connector back onto the board. I would not advise doing this if you are new to soldering!
If you can't then its a new motherboard, and HTC will not pay for it under warranty because its deemed damage do to excessive use.

no the only thing you can do is a new motherboard it is'nt possible to fix it i have had the same problem cost me 200 euro.

[Q] USB Port Not Detected

So, my phone is doing some weird things. It says that the USB is connected when it's unplugged, and says disconnected while the cord is connected. It won't charge anymore either. I tried cleaning out the port, different cords, restarted the phone, removed the battery and put it back in, formatted the phone, and nothing's worked yet. I bought the phone in March, so I might still be covered under warranty, but I'm currently in another country, so not sure if it still applies here. Any idea?

There are many cases of faulty usb ports on the Note, i suffered it too a few weeks ago and had to claim under warranty.
I think you should do the same, it's possible to do it yourself and there are guides and videos online, but if you don't feel confident in doing it then send off for repair.
Do you have any friends or family in the country you purchased the Note from? You could ask to use their address for the phone to be returned to.

sounds like a bad port :crying:
Mine is suffering to, but from self inflicted damage. Was plugged in, laying on a table with the end of the phone hanging off the table. Dropped something on the table at the end of the cord, and it bent the cord/usb port. If I plug it in, it charges, but barely touch the cord and it disconnects. I suspect the soldier connection is broken. Got a new port coming, but won't be here from China until mid January.
Watched the video on replacing it, other than a few screws and being careful, doesn't look too bad...been in the repair/electronics business for 30 years...with a magnifier glass, even these eyes should be able to do it :victory:

Another thing to try is to clean the usb port with pure alcohol and a cotton bud, this often happens with dirty ports where the dust etc shorts the pins easily fixable.

Thanks to everyone for your solutions. Turns out I just had to drain the battery all the way once to solve the problem. No idea what happened but all is working now.

[HELP] TouchPad fallen down. now not charging.

My touchpad was in a bicycle and was getting charged. My cousin placed the TP on a bicycly after the battery is about 43% and was charging.
He accidently shaked the bicycle and the touchpad was falled from the bicyle in the position where the charging port is connected.
Now it shows charging, but not charging. I plugged the charger at 41% and it came to 37% after 15-30 mins with the charger plugged.
Please help. Any DIY work that can fixthe touhpad or make the touchpad charge?
Thanks
Helps are appreciated.

Invest in a touchstone wireless charger. After the USB port went bad on one of my previous touchpads, it was a no brainer.

In webOS, when I connect it to a PC, it shows "Device May Not Charge"
How to transfer files?? Can I transfer files through touchstone? sorry for noob question.

Charging only. But in android you can use es file explorer to browse network shares and transfer over wifi.

What do you think about the problem? Can I fix it in some local shops? How much do they ask?
Thanks for your INFOs.

With a donor tablet, you could probably have it fixed. In my opinion, unless its a 32gb, 4g, or 64gb model, its cheaper to just replace it. When I sold my 64gb with all the extras, I was disappointed to see how low the value had dropped. Personally I would go the touchstone route, and in the meantime, find a cell phone repair shop that isn't afraid of surface soldering and have the connector replaced. No idea on costs, but the microusb connector is about a 3$ part. Only problem would be if the PCB was cracked, thus my thoughts on a donor tablet to just swap the sub board assembly with USB port.

Ok now imagine that i am in a cell phone repair shop. I tell the repairing man that the tablet has fallen down with the charging position downwards and now its not charging. Will he fix the problem? Time duration as my father needs it in 4-5 hrs.

You are from Chennai right? Go to any cell phone repair shop and ask them to fix charging port. It is a common problem in phones, and they might even have spare microUSB ports. I repaired one in Mumbai when I was there in Jan, and since I just re-soldered my existing port, and already had the unit open, AND I knew the repair guy, he only charged me Rs. 30 (~50 cents ), ONLY for soldering.
But if you don't want to open the touchpad on your own, and dont want to mess around, you can expect them to fix it for something like Rs. 200-300.
If they ask for more, tell them it is a cheap made in china (sorry, no offense intended) replica and you didn't even pay too much for it People usually don't know about Touchpads here.
You can also try those small shops that repair TVs or Radios, sometimes they also repair for cheap.

Thank you sir. You saved my life. I went to a shop and gave a 350 Rs and repaired. I said it as a china replica as you mentioned but he said that the quality is like a U.S or U.K made. So, He got the money mentioned above. Again Thank you so much.

Vivid charge port and audio port: some questions

Hey all,
I have replaced the charge port once already on my vivid, as it would no longer connect to a computer, and while the replacement worked wonderful, I noticed that after a couple months it got looser (cord wasn't anchored in as well) like the one I replaced, until one of the pins bent inward. I attempted to pull it back out but that just broke it off.
Are there any charge ports I can get that are more... Life proof or me-proof? More so than the original one.
Also, my audio port is being very picky about when it thinks there is a cord in it, making playing music in my car a hassle. Is Is his happening happening anyone else? Is there a way to fix it? Are there replacement audio jacks, or do I need to replace the whole case?
Thanks for whoever can point me in the right direction!

Lesson learned by me...
Spend at least $12 on your port...
I replaced 2 cuz I bought a $5 one and it lasted about 2 months...
The $12 one I bought lasted till the phone no longer took a charge... Got another year by buying that charge port and a $15 3500mah battery at the same time

Thank you, I've since bought another ~$15 port and it's doing fine so far. I also got my 3.5mm audio port working just fine again! I cleaned it out using a paperclip and got loads of dust and rubbish out of it, and now it's fine. Unfortunately the touchscreen doesn't work properly in a few areas, and reseating the flex cable did not resolve that issue, so I'm thinking I may upgrade to an Asus Zenfone 2 (still can't believe it's running an intel chip). Still gonna grab a new digitizer and repair, but my poor Vivid is getting pretty sluggish with my usage, and its age doesn't make it an appealing device to develop for, so the PAC rom is the newest we're gonna get for an OS.
Definitely gonna figure out a way to use it as a security cam though
