Question about LG KG800 Cellular Phone

Buttons stopped working

I've got a problem with the phone's keypad, can anyone tell how I open it up? I removed the battery and sim card, unscrewed the four screws from the back but what now? I'm a little hesitant to just pull but I can't see any other way...

My phone screen not working, key pad working but my phone was keypad locked. to unlock i need to press unlock button on screen but screen is not working .. i have restarted and remove memory, sim card also...


The reason your screens touch pad is not working is because the sensor board is no longer connected to the main panel of the phone, or the ribbon that connects the screen to the main board is faulty.

Try to open up the phone, by unscrewing it open from the back, then locating the ribbon and either try to reconnect it or replace the ribbon with a new one.

Remove your back cover, battery, sim, stylus and memory card. Now remove the cross head screw,
Lever the antenna cover off using a mobile phone opening tool.
Now remove the six screws you have access to.
Next you need to separate the battery compartment from the rest of the phone. To do so lever it away using your opening tool. There are various recesses in the back of the phone do allow you to do this.
The volume buttons are stuck to the side of the housing and need to be carefully peeled away. you can see the volume buttons after they have been unstuck from the side of the phone. You can now peel the large brown/orange ribbon away from the phone. It's held in place with double sided tape. The circuit board which the ribbon is connected to will come away with it. The on/off switch will be stuck down in the same way the volume button was and also needs to be peeled away when you remove the circuit board.
The on/off button will also come loose. Remove the screw, circled bottom left. The vibrating motor, bottom right, should be levered up so it is loose.
Lift the lower circuit board up and you'll be able to see another ribbon connector which needs to be disconnected. Again, it attaches like a plug and socket. Just lever this away from the circuit board to unplug.
To screen is held firmly in place with double sided tape and to remove it you first need to heat the screen (using a hot air gun or a hair dryer), then push your opening tool very firmly. You'll then see the screen raise slightly allowing you to slide something like a guitar plectrum or credit card behind it. Move your plastic tool all the way around the edge of the screen to release it.
You can now simply lift the screen away from the housing.
You should now have the screen removed. Reverse the whole procedure for reassembly.

Take care and good luck

Nokia 2100 keypad suddenly stopped working

Please try to open the pad and clean its contacts. below is the proceedure to open the phone (if it is not under warranty). you two credit cards and a screw driver.
  • Take front faceplate off by inserting card 1 between housing and silver key. As you pull up, take card 2 and slide it on the side of the phone prying the clips off.
  • Unscrew these 6 screws at the edges with the T6 screwdriver and release the 4 clips surrounding the LCD screen.
  • Slip the little black frame off of the LCD screen, and lift the screen. You should now see a screw. Removing this screw removes the back cover.
  • That’s it! Put your new faceplate or housing in and figure out how to put things back by following the directions here in reverse order.

Arrow failure

wicabix hello,

It seems like the keypad has moved perhaps because of a trauma to the phone.
I would suggest to send it to a lab if still under warranty.
If not, open the back lid, remove the battery. Then, unscrew both panels using a small screwdriver, and try to place the keypad in its right place.
Then, screw back on, put the battery in its place, and turn the phone on.
Good luck.

No response from keypad input?

check your volume keys or any side keys that get stuck... or if you can open your fone check its keypad for any shortage...

Try putting the phone in a very warm dry place, ay in the "Hot water cupboard" for a day or so and this may drive out any moisture that may be causing the problems, also shake the phone vigorously B4 you do so to try and dislodge any moisture. Or you could try disassembly and wiping the keypad contacts, perhaps there is still moisture there, or maybe it has shorted something else which is why ya gotta dry it out completely.

Moto v6 keypad problems

I have or should I say I had the same problem with my v6 maxx keypad not working. So I started to look into the flex cable replacement idea. I remove the back cover. Removed the Sim Card, Battery and Memory card fully intending to split the phone and have a look around inside. But then I came to a grinding stop when I saw how small the hex screws are. Gotta get me some of those. While I was there staring at the screws I noticed a small amount of dirt residue inside the back of the phone so figured it wouldn't hurt to give it a spray with CRC Contact Cleaner (it leaves no residue). I left the mobile in the sun to dry for about 3 minutes. Replaced the battery, memory and sim card and now it's working PERFECTLY.
Done. fixed. *** twas just dirt.
