Nokia 6600 keypad/key problem! I hope I've put this in the right section, as I'm not sure if this is a hardware of software problem I've posted it here, hope I'm right! icon_razz.gif

I bought a Nokia 6600 recently with a joystick that didn't go down. I replaced the keypad pcb, as there was a small tear in the ribbon at the bottom of the old keypad PCB. This fixed the joystick problem, but I now realise there is another problem with the phone!

The numbers 7,8, and 9 all display 1,2, and 3 when you press them. The '0' key seems to clear whatever's on the screen, so I suspect it's acting like the red end call key. It does this with both keypad PCBs installed, so I think it's another problem. Would this be the small gold contacts on the bottom of the phone, a software problem, or some other gremlin in the works?

I've had a quick search and someone suggested *#7370# to reset the phone, and someone else said it could be a keypad IC that's gone - any other suggestions? I'm at work tonight so can't get to the phone until tomorrow morning, and as the '0' key isn't working properly I can't check which software version the phone is running icon_frown.gif

Motorola karma. Only the red key works, none of the others is recognized. Took battery out, no help


Hi, most problem caused by keypad not functioning, is always water issues.

Unscrew the phone and clean up the keypad area. And your done.
After cleaning up the keypad,if it does not work, means that the problem is from the board of the phone.

There is an IC inside the phone that controls keypad function, when IC gets damaged, keypads will not function until it's replace.You will need to contact a skillfully personnel for help.

Thanks.

Hi my nokia 3110c...phone whenever...i switch the phone on...the keypad doesnt work..infact it just works a few seconds as the phone is loading..(enough time to unlock the keypad using the security code)...


Hi, when a keypad does not work on a phone, it is usually caused by dirt inside the keypad area of the phone,you can open the phone and clean up the keypad area.

Sometimes too, as the case may be Chips also can affect the keypad and allows the phone keypad not to function.

There is an IC chip inside that controls the function of the keypad.
You can fixed the IC chip inside the phone by replacing the damaged IC inside the phone.

When you replace the damaged IC .i assure soluton tothe problem.

Take care.

Keypad on W960i not working:- The number 7 key broken


I fitted a new keypad on my 960i some time ago (funnily enough for the same reason - no.7 not working!) and I'm pretty sure you will find that when your new membrane arrives, it is a complete unit with buttons and contacts all enclosed together, connected to the phones' circuit by a ribbon with a tiny plug on the end.. hope this helps....

The keypad do not work


Either a software re flash may help or a keypad replacement. Usually facial moisture could be a cause of this. i would recommend trying a blow dryer on the keypad for 40 seconds with out the battery to see if that fixes the problem

How do i lock my kepad pls


hi
first i want u to rate my work for u ok.

and the problem is that the nokia company made N73 without keyguard!!

i have found a solution.. you can download some freeware to install on the phone and this works well in providing the automatic timed keypad lock function. Suggest you all consider installing such software, if you want to avoid huge bills. Others are experiencing the same according to web searches ive done.

This problem is from your keypad Ic, Possibly it is working automatically. You need to change Keypad IC and then software re-install.
