Question about Samsung SCH-u740 Cellular Phone

Keypad backlight function turns off when call is connected

When making a call (either normal or landscape), the backlight on the keypad turns off when call is connected. This is very annoying at night trying to enter numbers for voicemail, etc. The backlight function is fine for all other uses (text, menu, etc.). I have the keypad backlight set at 'always on'.

    I too have noticed this on my brand new black Samsung sch-u740. the keypad backlighting goes out as soon as the call is connected. can't even find the END key to hang up in the dark. can't enter passwords or press numeric response buttons. only workaround i have found, and it's a bad one, is to call in landscape mode and tilt the screen down to light the keys. irrespective of ALWAYS ON for keypad lighting or 30 secs.

CHECKING KEYPAD OPERATION
A rapidly blinking LED over one of the keys of the keypad (or sometimes a "dead" keypad/console)
To determine if the control or keypad is faulty, do the following test:
1. Unplug dishwasher or disconnect power.
2. Open the dishwasher door.
3. Open console and disconnect the keypad ribbon connection from the control (at P1).
Make sure all other connections are made.
4. Put console back together. Do not close the dishwasher door.
5. Plug in dishwasher or reconnect power.
6. Wait 5 seconds.
7. Close dishwasher door.
8. Monitor the control's response:
If the control is OK (no longer sees shorts with the keypad unplugged),
it will respond by turning on a Drain Motor for 2 minutes.
Check and/or replace the keypad if the control responds OK.
If the control is not OK (still sees shorts with the keypad unplugged),
then the drain motor will NOT respond and will remain off.
If no response, replace the control.

Why is my 7360 keypad stuck on BUSY???!!


Something is causing a short on the keypad bus. It could be wiring, or the panel could have had a power surge. There is also a jumper on the main alarm panel board that could be shorted. Open the panel, and make sure there is no connection between the pins in the middle of the board marked RESET. If that isn't the issue, pop the keypad off the wall and make sure that there isn't a connection between the yellow and green wires. The wires are on a harness connected to the back of the keypad, so follow them back far enough to see where they connect to the wire going to the panel.

All buttons have stopped working


Hi, different possible places to check,
The flex,
keypad IC.

The flex of the phone.
The flex is connected to the screen and it makes the screen display,Also if the flex gets damaged it will make the key pad not to work.

The keypad IC is found inside the phone boardand it make the keypad the function.If IC gets damaged, might cause keypad noe to function.

It depend of the keypad your talking about, if it's the lower key pad or the upper keypad where the menu is.

If it's the upper keypad is damaged, that means the keypad area is faulty,and will need to be replaced.

Have a nice day.

How to use the letters on iphone keypad


Hi, initially you might be having issues with using keypad on iPhone, but as you practice, you will get a lot better at it. Initially, try using the keypad with your index finger, and do that for atleast one week, before jumping into using both the hands.

Also, turn on your dictionary, so that even if you type wrong, auto correct will help you get the words right, without having to erase and retype. If the guessed word is not what you want, click on the 'x' on that word, so the word doesnt change to the suggested one.

If you are still having issues, use the landscape mode which didvides the keys into broader space, and the typing gets lot easier. There are few apps, on iTunes store, for free, whihc you can download (for ex: easy email free), so that, even for email, you can type in landscape mode.

Post back if you have any more questions.

Keypad light wont turn on


It is the problem of your ribbon flex that is connector..
If you have not a good hand you cant do it. Take it to a Motorola Repair Center.

I'm sure the phone will be full functional again.

Backlight display not working


Hey Dannes1956,

The Motorola V3m has a light sensor, which is visible just above the right soft key -- the key above the CLR button. This light sensor turns the backlight on when you press a key in the dark and disables the keypad backlight when you are in a well-lit area.

Your phone sounds like it's operating normally. I believe they disabled the option to activate or deactivate that feature.

Hope this helps,
cHiPz.
