Nokia s mobile phone keyboard is out of order

It's not the wires, it's the water on your hands. It was water that got into the keyboard and short-circuited the keys inside!! You go to a random place to repair your phone, disassemble the phone, wipe it with something, and wipe it off with water!

You have to go early, or the corrosion will be worse!! My classmate's is also in that situation.,It's late to corrode the copper inside.。。。

Hope mine is helpful to you

The repair shop you went to was not very professional or responsible. Water ingress may be bad on the motherboard, a few days may be a few days after the motherboard power-on position of the liquid volatilization loses conductivity, the mobile phone can maintain the boot, but this is also more dangerous, not necessarily affect the **, liquid inlet is a very random form of failure. The keys are identified by the CPU through a series of coupling elements (the CPU is very expensive and basically scrapped when burned).

Whenever there is a problem in any of the links, the error will be identified. It is better to do a full-page cleaning as soon as possible, and make a special inspection according to the serious location of the liquid ingress. The sooner the better.

Wiring,How can there be so many wiring in the mobile phone。。。 There are at most two lines in the mobile phone, and the process of making the mobile phone is too doubtful. You have to have a certain hands-on foundation to do it yourself, it should be the keyboard or motherboard which solder joint is soldered, you first remove the back cover can be removed, and then take a knife to pry little by little, there are screws to solve the screws first.

But you'd better send it for repair, and the kind ones won't exceed 50

It has nothing to do with the wiring.,It's not water or your keyboard is old.,Change your life to the end.,Take it to find a mobile phone repairer.,7373 has been discontinued.,So I feel like yours should be water.,And the second floor.,7373 is a s40 machine.,It's not a support for grid machine instructions.,Don't talk nonsense if you don't understand.,Waste people's eyeballs.。

The keyboard is faked, just like I used to, let the phone repairer, open up the black thing that wants to capacitor under the keyboard of your phone, just take it away, I'm the same as you, it's okay to go now.

The phone is playing and suddenly fails, the left soft key can't be used, but the left arrow button can play a role at the same time to the left water can not be guaranteed, so you go to the after-sales repair is estimated to be dozens.

It could be a line problem, go and find it,

The screen will be reversed.

It must be a problem with the wiring.

I've had this with my previous phone.

It is not the cause of water ingress pulling.

It must be that the cable in the store has not been changed properly.

There is a problem with the wiring.

Repairs are recommended. Change the cable.

Individually, the contacts are broken.

The whole thing is that there is a problem with the cable of the keyboard.

Press 7370 grid to try it when standby, if it doesn't work, it's a hardware problem. Send it to customer service.

Are you a slider? I've been in this situation and it's a wire error.
