Question about Samsung SGH-d807 Cellular Phone

1 Answer

Is this what it's supposed to look like when i ripped the Ribbon off the LCD and circuit board?

Ok. When I yanked off the ribbon on the LCD, I got some gold things attached to the green tape like this:

I just wanted to ask if it was normal for those things to get pulled off. Here's the picture of the LCD and Circuit board after i took off the cable.

Altogether, I just wanted to ask if I'm still able to buy a ribbon cable and replace it. I don't know where the gold things came from. Hopefully, it didn't come from the phone. But if anyone had this problem, please notify me. Because I don't know if a new ribbon cable would still work. Thank you.

I have cell phone lg kp170 with a display prpblem. the set only gives white light and doesn,t show any display and seldom lcd light flickers with intervals and seems as set is going to be restarted


First of all, you need to understand that the phone has a problem that is why it is having the flickers, white display and tending to look like it wants to restart.

The first solution to try out is for you to flash the phone with the appropriate software and cable be cause the phone might have contacted some kind of virus, either by file transfer from other devices or downloading of corrupt files. By flashing, all forms of viruses will be erased.

Also, the flexi ribbon that connects the screen to the main panel might be faulty, and to repair this kind of problem, you will have to unscrew the phone open and replace the ribbon. To replace the ribbon, follow the process below:
  • Remove your back cover, battery and sim. Remove the four screws you can see.
  • Run something like a credit card all the way around the join of the battery compartment to release it from the rest of the phone.
  • A number of clips, such as those by the upper left, lower right and that which is connected to the camera, hold the circuit board and front cover together. Release these clips to remove the front cover.
  • Turn the circuit board over. Release the clips that hold the grey part to the circuit board but make sure you don't break the two wires soldered to the circuit board. Top right is the ribbon from the LCD screen. To release this first remove the blue sticky tape then flick the black latch up.
  • That is the ribbon that needs to be replaced.
  • After replacing the ribbon, then you can reverse the process the reassemble the phone together.
Take care and good luck

NB: If you are not familiar with such process, i will advice you seek the assistance of a professional phone repairman, in order for you not to further damage any component of the phone.

  1. Remove your back cover, battery, sim and memory card. Remove the six screws (two at the bottom are covered by rubber stoppers which are easily removed). You can now remove the battery compartment.
  2. Below you can see the battery cover removed. You now need to disconnect the circled ribbon connector. It attaches like a plug and socket. Simply lift the connector up to unplug it.
  3. Lift the circuit board up to reveal another connector. It attaches like the last one. Unplug this
  4. You can now remove the circuit board. Note that the ribbon running along the right of the circuit board, with the volume buttons at the end, is lightly stuck down with a tacky glue or double sided tape.
  5. Remove the grey part. Note that the ribbon with the camera button at the end is stuck down lightly. Next remove the four screws.

How do you make my screen work? All the buttons work just not the screen buttons


The reason your screen wont work is because there is a problem with the flexi ribbon that connects the screen to the panel of the phone.

To fix the screen, you would have to dismantle the phone and replace the flexi ribbon.

To disassemble your phone, you have to follow the process below;
  1. Get the appropriate screwdriver(Phillips screwdriver, plastic tool such as a guitar plectrum or credit card.),
  2. Remove your battery cover, your battery, your sim and your memory card,
  3. Remove the four screws you can see.
  4. Peel back the sticker. You may need something with a thin, sharp point to peel the sticker back ( Two rubber stoppers need to be levered out to reveal two more screws that must be removed.
  5. Run your plastic tool along the join of the battery compartment to separate the phone into two halves. Next you need to disconnect the ribbon. This attaches like a plug and socket. Simply lift the connector up, away from the circuit board to unplug it. Remove the screw by the left. You can now lift the green circuit board away from the phone. A little force is required.
  6. You should now have the circuit board removed. Note that a ribbon, will have disconnected when you removed the circuit board. Again, this attaches like a plug and socket.
  7. Remove the identification sticker. Remove the volume button which will be loose. The buttons underneath will be lightly stuck to the side of the phone and need to be peeled away. Lever off the grey part.
  8. Remove the four screws you have access to (one is under the ribbon cable).
  9. You should now be able to separate the phone into two parts. Two rubber stoppers need to be levered out to reveal two screws. Remove these plus the two others screws you see.
  10. Run your credit card around the join of the housing to release it. Once you have the two parts separated as far as shown below, pull in the upward direction (towards the camera).
  11. Pull the little metal bars in the direction of the camera.
  12. Lever out the camera, speaker and ringer. They'll be stuck down with double sided tape. Lever out the the screen. Slide your plastic tool under the green circuit board to release the LCD screen.
  13. You should now have the LCD screen removed,
  14. Turn the screen over. Remove the green tape at the top. Now release the circled ribbons. To do so, flick the black latches up and then pull each ribbon away.
  15. That is the ribbon that needs replacement.
  16. Reverse the process to reassemble the phone back together.
Take care

Only get sound out of left ear plug, no sound to right ear plug in music player & radio


It is clear that the problem is from the right speaker of the phone.

To fix this,
  1. Remove your back cover, battery, sim and memory card. Six screws need to be removed,
  2. With a little force you can pry the battery compartment off. The volume and camera buttons will also come loose.
  3. The micro switches for the lock button and volume button are stuck to the side of the phone with double sided tape and can be carefully peeled away from the side of the phone leaving them still attached to the circuit board,
  4. Pull the circuit board towards you and you'll see a ribbon connector. This attach like a plug and socket. Just lever it up, away from the phone, to unplug. The circuit board will now be free.
  5. Again, each attaches like a plug and socket. Just lever each one up to unplug. The part that is attached to the circuit board at one end and attached to the phone housing at the other end with double sided tape. You need to carefully lever it up to release,
  6. You can then lift the circuit board away from the phone. Note that another ribbon connector will disconnect as you remove the circuit board. Now remove the screw circled in blue. Remove the antenna by prying along the dotted lines that is below. As you remove the antenna, another connector, circled needs to be levered up. Again this has a plug and socket type connector.
  7. Next, carefully peel the identification sticker off. Then push your screwdriver into the . This will release the keypad on the other side.
  8. The connector below connects in a slightly different way to previous stages. Just flick the black latch up, opposite to the side the ribbon enters its socket. The ribbon will now be loose. Now pull the front cover in the direction shown by the arrows to manipulate it so that the front cover separates from the black metal plate, indicated by the dotted line. Some force is required.
  9. The ribbon is the one you released in the last stage.
  10. Now slide something like a credit card all the way under the LCD screen to release it.
  11. remove the speaker and replace it with a new one,
  12. You should now have the LCD screen removed.
  13. Reverse the whole procedure for reassembly.

Samsung sgh-d807

I just finished disassembly and it wasn't that bad. Take off all four screws around the battery, then carefully but forcefully take the plastic casing off. Then, take the 2 screws on the main circuit board. That will reveal one connection for the ribbon cable, take that off. Under that is the backplate sliding mechanism of the phone. There will be 6 screws on this assembly, one of them under cable the connects to the keyboarb (bottom right). You will have to take off a green tape and also a gold padding to get to this final screw. After that is off, you will see the other half of the ribbon. Take that one off also, just yank it off. Install the new ribbon tape, make sure you don't rip it, and you're set. good luck. EE
