Keyboard issues with e71 5, keyboard issues with e71

Keyboard problems with the e71 are hard to be universal! I spent 80 yuan and didn't fix it. Later, I cleaned it up myself, and now it's also improvised!

This problem is not very representative, my machine also had this problem some time ago, and the direct cause was that I dropped the machine.

The symptoms are also manifested as the failure of the function keys, and the 369 keys are also out of order at the same time, and the online data shows that these keys are controlled all the way.

Later, I went to the mobile phone repair point to repair it, and the reason was not as mentioned in the above answers, but that a component near the keyboard cable was desoldered, and it was blown with a hot gun.

When you go to the place where the phone is repaired, you should be able to open it and deal with it, the key has been pressed for a long time, and the contacts are easy to oxidize, resulting in poor contact.

If the key contact is not real, go to the maintenance point to replace it, about 50 yuan. Customer service**I don't know, you consult.

Mine is the same, it's a hardware problem with the phone, protect ...... well

Press too much... Let's get it repaired.

There are several reasons for the failure of the general keyboard: 1. The keyboard is broken, the second is that the motherboard is broken, and the cable connecting the motherboard and the keyboard is broken.

This may be a common problem of e71.,Mine is the same.,It's not good to use the keyboard often when sending messages.,Turn it off and turn it on again.,It's annoying.,I feel the same way!

Haha, there's a very simple reason for this, I don't know if you've noticed? That is, the software、The game is stuck, and it is recommended that the next cleaning software try not to use the C disk space。

Use the screwdriver of T5 to remove the white layer on the keyboard, which can be removed, hehe, don't shake your little hands. (Peel it up and down, and it's almost around the space bar) It's easy to lift. Then you will see that under the white layer is a concave metal iron sheet attached to the bottom, and under the corresponding iron sheet is the PCB circuit board of the keyboard.

A look at the circuit board is estimated to have been used for a long time, and there may be glue on it, many places have grown a piece of patina, that is, patina, so I took a knife and carefully scraped off the layer of patina, remember to scrape carefully, don't use too hard, don't scrape the line on the board, I have been slowly scraping until the bright copper color is exposed.

After scraping the rusty part of the PCB board, I saw if the metal sheets pasted on the back of the white layer were also rusty, or there was glue that had been glued to it because it had been sliding for a long time, and my monster had to be able to use it, and the glue adhered to the metal sheet, and it turned black, blocking the connection with the PCB board circuit when pressing the metal concave plate. The treatment method is also carefully scraped clean with a knife.

After cleaning up, quickly install the battery experiment to see if it is the crux of the problem.

If you really can't do it, go ** and buy a keyboard. I saw the original one on a keyboard board** 130 oceans.

Here are a few things to consider:

1 hard grid (first back up the data, then shut down, at the same time press and hold the * key, dial key, 3 key, power button, until the boot screen appears hand in hand and then let go, otherwise the machine is 100% scrapped!! It is strongly recommended not to have a soft grid, that is useless!

2. Change the keyboard, it is best to buy Ouku.com, the credibility and quality are not said! After buying it back, take the repair phone to change, so that the ** down to the minimum.

3. There may be dust inside, open the back cover to remove the battery, blow the hair dryer towards the keyboard, and then turn on the machine and try again.

4. Check if there is a software conflict, and if there is, just uninstall one or two of the conflicting software!! It's easy to overlook this question.

This shouldn't be a big problem, you try the soft grid to see, first back up the business card, text messages or something, and then enter the standby state * After formatting, if it doesn't work, you can try the hard grid again. Back up your data first, then turn it off, and press and hold the * key, dial key, 3 key, and power on button at the same time until the phone is turned on and then let go. If it's not a hardware problem, it can be solved.

If it doesn't work, it may be a problem with the keyboard.,Go to the repair point to see.,It should be able to be solved.,It doesn't cost a lot of money! Good luck!

I can't solve it myself.,Take it to customer service to write the information.,If it's a virus, it'll be OK.,If it doesn't work, change the keyboard board.。 My personal experience is that your button board is broken, just replace it.

Let's change the keyboard, the keyboard and the underneath cushion are separated. I had a water ingress failure and a leather cushion.

**Looks like there is a keyboard for sale.

If you don't know how to get it, take it and let the cavity repair the mobile phone scum, and it won't take a few dollars, but it is recommended that he fix it on the spot, and you watch it yourself, otherwise you will leave there, and maybe he will do something to your first mobile phone.

The long-press button, which is the K key and the L button, really only came up with two other strings.

If the keyboard is used for a long time, it will continue to come out very quickly, and the rubber pad will deteriorate, and it will not be broken.

Mine is also an e71. Press the * button and it will come out. Long press it becomes Bluetooth, and then long press it to turn off. If you press and hold a little bit in between, it will come out continuously*. Is there a little bit of a problem with your * key, or is there a little problem with mine?

The other two keys, k and l, are the same for mine.

Let's go to the Nokia repair department to fix it.

It takes a professional to solve it.

I haven't dropped my 71 until now.
