Question about Pantech Matrix Cell Phone

My pantech c740 keyboard suddenly stopped working. The only thing I can do is make calls. I can't even accept a call when the slide is open. I believe the only button that is working is the "red"button.

Hello,

I think your phone's keyboard/keypad is defective, that's it's not responding. Also, it is possible that the flex of the keyboard/keypad may have loosed contact.

So, now you will have to disassemble the phone to actually find out if the keypad is intact and has no damage flex.

Turn of the phone, remove the battery, get a torx screw driver, remove all the screwing holding the phone together, use a flat torx screw driver to pry the phone case from the side to get it apart and check the keypad. Make sure it is intact and try again. You don't need to couple the phone back before test it. You can put the battery and test it before put the phone together.

If you feel you cannot perform this task on your own, you can call a family or friend that you feel can assist you. (two heads are better than one).....

If you don't find any obvious problem with the keyboard/keypad or it's flex, then you will have to replace the keypad.

I hope you understand the above.

Good luck.

Generally, when a cell phone's keypad is not working properly it could be one of three different reasons:
1- Due to shock from a drop, circuitry is damaged thus no matter how hard you press you will never get the phone to register it. This issue is one that a certified technician would have to take care of and is nothing that we can fix here as it would be time consuming and expensive.
2- Because of moisture or heat, again, the circuitry could be damaged. Nothing to be done here really. The only thing to try best for a phone that's been subjected to moisture is to place it in a sealed container with rice. The rice will draw out the moisture and if there was not too much damage the phone should work fine
3- The phone's keypad membrane is broken or dented.

Pantech MATRIX C740 slide hinge has come loose. How do you take the phone apart to fix? (Pantech Matrix and Duo are not the same phone)


i suggest not taking the phone apart. 5 of my friends and myself have the matrix and after flipping it a couple of times the hinges are always going to feel loose. they have felt that way on mine for over a year. and if you take it apart, the senor bars for the keyboard will go out and you will have to get a new phone or just use the number pad

Pantech c740 screen only shows white


Many users of the Pantech phones have been experiencing the same thing. There are a lot of default in this phone. I would suggest you to return it to Pantech and try to get a software upgrade (if there is!). Although, I would recommend you NOT to use it. Even if the Pantech exchange it for a new one, the same problem will happened in a day or two.
