The common line to these keys are cut or disabled from the filter or connector if any..you actually need the circuit diagram of your device to surely fix it..but try this...using an ohmmeter, check if one terminal of these keys are connected to each other..it's either the inner or the outer terminal..take note of the connections of these keys..take note also of which terminal of these keys are connected to a functional one..it's a bit tedious but you will know when you need to bring it to the nearest repair shop..

Keypad button problem


Key pad could be possibly as simple as a key pad replacement or more. This can be determined by opening up and looking. You may get "tamper" message after assembly. Call Frank @ 775-338-6634

How to repair keypad problem in China Mobile


First we need to know china phone keypad connected with PCB how way
(A) Direct on PCB
(B) Flex System (flex cable direct soldering pcb to keypad panel)
© Flex and socket system include (flex one side soldering with key panel other side connect to pcb with socket)
(D) only Socket System (here have 2 socket, 1 with key panel others with pcb)
Keypad problem have various type
1. All key not work.
2. some key work and some other not work.
3. sometimes work and sometimes not work.
1. All key not work
china phone all key not work for this type of problem
(A) though its touch screen phone, first try to disconnect touch panel line from phone pcb or display flex (4 line)
(B) though not solve and keypad direct on pcb first you try to good clean full pcb with cleaner.
© though not solve now you try to format/flash your phone because some time key problem come from software problem.
(D) though still not solve now you check must be CPU. 95% china phone keypad directly going in cpu. and other 5% first going to resistor or capacitor near the cpu or keypad than going to cpu. so now first check them than you can try to re-hot, re-soldering or changing cpu.
(E) though its flex or socket system, first check GND connection continuslay pcb to key panel. next check full flex or socket all line going continuously pcb to key panel or not. also sometimes flex or socket shorted with other line or gnd so check also them.
(F) Also you can check all key anyone is short 2 line.
(G) sometimes keypad line broken from cpu pin on pcb to key panel, so check them.
2. Some key work and some other not work
Some key work and some other is not work for this type of problem
(A) maximum time this problem we face for flex or socket system keypad. so check flex cable and socket all line any line is broken or not and though need change them. and check all key connection on key panel.
(B) though its direact on pcb, some of key line broken internaly. and maximum china phone have alternative test point near every key or with other key on keypad. so check them with multimeter and though need connect to not work key with near testpoint or other working key.
© common problem is keypad metal ball (which is short 2 line on key when we press) sometimes its damage for phone water damage or over key voltage, so clean them or change.
(D) also try to check line continuously from cpu to not working key.

3. sometimes work and sometimes not work
this problem come from this defect
(A) flex or socket system keypad any line is bad soldering or do lose contact. check them and
re-soldering or keep there line join with extra ware.
(B) for cpu bad soldering or cpu pin is broken. so re-hot or re-ball cpu.

Jvm errore 517 in bb 8320 how can i solve


Hi,

To correct this, follow the steps outlined below from RIM:

1. If not already installed, download BlackBerry Device Software and BlackBerry Desktop Manager from the wireless service provider web site.

2. Install BlackBerry Desktop Manager and then install the BlackBerry Device Software.

3. Use Application Loader to reload the software on the BlackBerry device.

But, if it is on warranty, it is better you go for a replacement.

Good luck

Dream Maker spa - does my dream maker spa 4 person have a thermostat or temperature sensor that can be changed out? Or, is this all in the topside control panel or CGA control box? I'm having issue's with...


Depending upon the age, the Dream Maker has a digital thermostat which is easy to change but to be honest I don't think that is the cause of your problem.

Check the keypad connection on the PCB (circuit board).

t could be either the keypad or PCB at fault and withou trying one or the other you'll not be able to determine the problem. My advise would be for you to contact your local parts supplier and ask them whether or not they can supply you a keypad to try with the option to send it back for a refund if it doesn't cure the problem.

A keypad can be trial fitted to the PCB, just unplug the old one, plug the new one in and turn on the power. There's no need to install the keypad to the spa, therefore you wont damage it in anyway.

If the keypad doesn't cure the problem, change the PCB.

Regards,
Ian.

One method to fix where an electronic device has a stuck key is to thoroughly clean it with a high percentage isopropyl based rubbing alcohol and a cotton swab.

You may also try to reset your blackberry to factory defaults by following the steps in your user manual for a factory reset.

My buttons wont work


i think the moisture has entered into the keypad sensor where it must have shorted the leads on the keypad board...
you should remove the keypad layer and make it dry thoroughly..
i would advise to take it to the service center for curing the keypad asap....if the phone is under warranty you can take it to the customer care
