[SOLVED] Expo slide out keyboard problem, hardware or software problem?

Hi all, I've bought LG eXpo, I have problem with keyboard. Don't know it's hardware or software problem. I slide out the keyboard, type "a" and it indicates "aj", type "u" and it indicates "ud" so with some other keys. I really need your helps. Plz. Thanks!

Thanks you first, I will give you some information:

On the qwerty keyboard, besides the error keys "a" "u" "d" "i" "f" "o", other keys are ok.

The phone is brand new, never open.

I flashed the newest official ROM for it but still the same.

=> Maybe it's hardware problem. Because I tried many ways to solve the problem. I've used Windows Mobile Phones since 2003 with a lot of devices but this is the first time I used a LG phone so lack of experiences of this phone. Any solution? Plz help me. Thanks for your support!

I live in Viet Nam, this Expo is my gift from my uncle, I've just received it yesterday. Original package, everything new but the phone has a stupid thing with keyboard. I have a question: I think I will send it back to US for repairing, is it possible? I mean the AT&T supporter will accept my phone? If they require repairing fee, it's not a big problem. Thanks!

thanks for your suggestion, I will keep it in safe and follow this thread while using my old Touch Pro, more keys but better than Expo now, 

That's right, it's hardware problem. After all, I've been successful to repair it without sending it back to US. I have disassembled it and found that the keyboard control chips were loose because of the damage. I used the soldering-iron to take them out then reassemble them. Everything is ok now. If somebody facing with the same problem and no more warranty, you can do as I've done with your own risk.

Step 1: Take out the screws (4 screws - 2 each sides) make sure you had taken out the battery, memory card, sim card.

Step 2: Take out the screws (2 screws) near the sim card slot.

Step 3: Use your finger nail to disassemble the cover, it's quite easy.

Step 4: Now you can see the mainboard *NOTICE: you have to turn it up from right side to upper left, SLOWLY because the display ribbon cable is under the mainboard.

Step 5: Use a clip to take out the display ribbon cable socket.

Step 6: Now you can take out all the mainboard, let see around the keyboard circuit here, there is a plastic film cover it. Take it out using your finger nail.

Step 7: There are two keyboard control chips at the upper left and right of the keyboard circuit. That's the problem.

Step 8: If you have soldering-iron, you can weld it with a little little lead.

Step 9: After all, reassemble the cover and put the battery in, power on and check your keyboard. (I have to assemble and reassemble at least 4 times to finish)

Step 10: Put the plastic film back to the keyboard, there are 5 led indicator so make sure you don't cover them.

Finish! 

Thanks all your support and advise, I hope I can help all of you!

+1 for busting out the soldering iron and gettin 'er done! And have a cookie for sharing the details with us all

Yeah you're right, but time is not my problem. You know that I'm living in Viet Nam and if I send it back to US by FedEx or UPS, it costs me around 1.5 millions Vietnam Dong (VND) (~100USD) for transportation fee. Excluded the repairing fee in US, when it's sent back to me, I have to pay for tax because in Vietnam, import cellphone from other country will cost about 10% of the price of phone. So if I do this way, I have to pay more than 3 million VND and with this money, I can buy a new one and maybe better than eXpo. :p

I will soon upload the diagram/schematics of LG GW820 here for everyone, I thought it would be something interesting. You will find that the eXpo are very simple inside and easy to disassemble. :p
