Attention!! The hardware of Himalaya is NOT so strong as it seems!
The Himalaya is using stupid charging connector(reduction),that is too big and dangerous for the system connector. Once in night I want to answer a call,then I've broken the built-in system connector off the mainboard. Normally in service You can pay for a new mainboard lot of money. I've just broken the warranty and I've repaired it myself. The connector pinout density is very high and therefore I need to use a micro-solder to repair. Well I've successfuly repaired that,but other people couldn't have this luck. Afterwards I need to clean the solded pinouts using IPA(Isopropyl Alcohol). Then was the joystick functionality damaged. I've cleaned it one more time and now is it working.
Therefore BE CAREFUL! for your lovely Himalaya.

Hi, I bought an XDA second hand and apparently they wont touch it under warranty. They claim its my fault and say I broke it anyway!
Now, it all works when opened like a laptop, however when I rotate the screen and fold it flat like the old XDAII, the touchscreen stops working.
If i rotate back to landscape mode, it works again.
Ive done a hard reset, and firmware upgrade so im sure its not software.
I assume there is a dodgy cable in the hinge, does anybody repair these, or can I do it myself?
suggestion
Ask for the supervisor

Cable connector sounds loose - the cable is many thin strands so if it was a broken cable it would stop working completley. You need to diss-assemble the screen module and re-seat the push fit connectors. If the warranty seal is still intact contact the XDA helpline.

b4 u dissemble just try pressing at all the corners of the exec...u can get it working..
I took it apart, the connector was NOT loose
Now, it seems the cable is broken inside one of the wires.
Im screwed. I have a brick.

Can you see it's broken? Repair it with a bridging piece of wire. You can't buy the looms so unless you can repair the broken wire you do have a brick :-(
Use a multimeter to check for continuity of the wires.

hi
my usb socket on my universal snapped!!
anything I could do about it?
can I get a new socket and solder it?
please help!!
Pocket PC Techs can repair.
If you feel confident and with enough ability to do such a repair, you can do it.
I might even buy some of those little mp3 devices that doesn't cost too much instead of trying to buy a brand new connector that migh cost even more, take the connector out of it and resolder it inside the PDA.
Be sure to get universal's service manual (go and search for it in the wiki) before you attempt to open it, have all the tools with you when you begin, use a safely grounded solder and proceed carefully.
When you finish, clean up carefully and you should have no problem, it might sound harder than it is.
good luck!
FIXED
thanks for your replys
me and my friend actually soldered the broken socket back and it worked!
Awsome, great work
I can't charge my beloved hd2 anymore. Apparently the USB connector broke off Opened it up and as soon as I unscrewed the main board the USB connector just fell out. Is it even possible to fix this??
Yes should be repairable, either exiting USB socket can be resoldered or a new one can be obtained & soldered to board.
If you can't do the soldering a local repair shop can do it & cost should be low as you doing time consuming work of strip & assembly.
Not a big fan of the micro USB, the mini was far better in terms of reliability & connection capability (extra pins could feed audio & video)
Epoxy resin or PU40 could be applied around USB socket after successful repair to help support it during use (not too much or may hinder future repair) ... factory implementation of this sockets attachment is cheap to be polite.
Thanks for the prompt reply mister b I was just concerned coz I thought it was just one pin that came loose that would be quick to resolder, with maybe a little residual left over on the board for me to work with, but when I saw there was nothing left on the board at some pin connection points I got really worried. Thought I'd have to replace the whole board to get it fixed lol. Don't know much about these things so I'll probably be getting it to a repair shop. Thanks again
Yeh give it to a trusted shop as board is a bit chewed up & if they are successful try & support usb socket via adhesive as the board fixing repair may not be as strong as original & original was not that good
I need help with broken lcd flex cable connector on motherboard!
I want to now is another connector fits for Trophy
Nothing?
Nobody knows any solution?
I had this happen on my Touch Pro2, but the cable still worked fine after inserting it. Maybe try a bit of electrical tape on top? I don't know if the facing side on the Trophy connector (the side that is broken has any data carry over or not?)
It's some pretty high level damage to do either way.
I try, but not work.
I hate to say it, your out of luck. :/ Unless you can find someone that can do awesome high level soldering and has access to the parts to replace it... that's it. HTC might repair it at a cost, since the phone isn't under warranty anymore, but you'd have to contact them and ask them if they would and what the price would be.
I buy one with broken LCD and Touchscreen and now I have a working Trophy.
Only thing is to change stock ROM with custom ROM.
hi all,
recently, i found CM10 had been successfully ported to thinkpad tablet, but at the same time, my vol+ button was broken.
How can I boot into CMW without Vol+ button?
I tried "reboot recovery" but there is nothing change.
BR,
Ben

I suspect you're a little stuck without the relevant hardware buttons operational. The keypress sequence to boot into the recovery partition will be coded in the bootloader which is relatively uncharted territory. ROW devices are supposed to have an unlocked bootloader but you're a braver man than me if you tinker with it.
Is your device still under warranty? If so, you're best off sending it back for repair. Though I'm assuming that yours has expired since you're asking here. Even if the warranty has run out Lenovo would probably still agree to repair it ... with a hit to your c/card of course.
You could try disassembling the device yourself using the instructions in the service manual (http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/0a96158.pdf). Reports elsewhere say its not that difficult. If it's just the plastic mount that's broken you could attempt a repair or remove it completely and cycle the switch with a pointy device. If the switch itself is broken I hope you're good with a soldering iron or know someone who is.
Many thx, it is extremely easy to dissemble it..haha...i fixed it la...thz a lot!
One more question, my micro-usb also broken, can I buy a micro-usb to replace the broken one?

Your TPT has lead a hard life
Do you mean the cable or the TPT socket?
The cable is generic ... just look on ebay.
The socket will be specific to the TPT and not easily replaced. If it's just come off the mainboard you may be able to solder it back on. Otherwise, if the internal pins are broken you're out of luck. Talk to Lenovo ... they may be able to fix it for you.
you should be able to fix everything with a soldering iron
i dont know which usb connector they build in, i need to take a look but in general lenovo also need to buy them from somewhere so the chances are good that you will find a replacement connector somewhere at mouser, digikey, rs-components, farnell or somewhere else.
normaly the micro-usb is a SMD Component, so you can use a desoldering wick and soldering iron to remove the broken one, and then replace it with your new one.
i would not recommend to solder down broken pins, because mostly there is also a mechanical deformation inside the connector, so it will not work. replacement connector cost you about 1$...
if you have never soldered before, you probably need some help there, because SMD Soldering is very special and you can ruin your pcb within seconds if you dont have the right equipment and expertise!
edit: as far as i can tell from these pictures: http://www.wirelessgoodness.com/2012/01/06/lenovos-thinkpad-tablet-gets-an-fcc-tear-down/ the micro usb should be "easily" replaceable, seems to be a standard component...
