How do i install the keypad with flex cable throught the hinge on a v3?

Yes this is the most common problem with the RAZR.

There is a small cable connecting the screen to the keypad part of the phone. This cable is called a flex cable and fits through the hinge of your RAZR so that the screen and keypad are connected even as the phone opens and closes on the hinge.

BUT, this cable often wears out or can even be severed even a slight bit, and the phone would then work, but only the bottom half, the screen would be dead. I fix this issue for people more than any other cell problem. You need to have the flex cable replaced.

The LCD flex connector is very sensitive. 4/5 of the RAZR screens I see go out are due to a loose flex connection. It's super easy to fix it. Take off the battery door. There are two T6 screws. Take them out and pop off the bottom of the phone. There are two flex cables: one for the keypad, the other for the screen. Connect the flat cable (screen cable) first. Then connect the bent (keypad) cable. Put back together. Voila.

hi
The Phone needs a new Keypad flex and most likely a left hinge pin. When the phone is open, the cable runs through the left side of the hinge. It is very common for the hinge pin to become chipped and put a small cut in the Flex Cable.
You can get the parts on ebay. search for motorola v3 keypad flex, and motorola v3 hinge, or knuckle.

thankyou.

You can buy a new phone.....but I had the same exact problem with my motorola v3 phone. Every now and then both screens would work for a while and then turn completely black or sometimes white. Most of the time black. The keypads would light, I could make and receive phone calls, but I couldn't see anything on either screen. I moved all my contacts to the sim card and I got a new phone thru an upgrade with my company. But I was still determined to get the V3 to work again! I brought the phone to a few cell phone repairs shops and I was told that the connectors from the flex cable inside the phone sometimes get loose. Make sure they are tightly plugged in. If that doesn't help then the flex cable needs to be replaced. Some of these repair shops wanted up to $65.00 to replace the flex cable! I could replace the phone for much less than $65.00! So I decided to go to ebay and type in Motorola V3 Flex cable......hundreds of places came up that sell this flex cable. I found a place in my area and ordered one. It cost me $5.00 and I got it within 2 days! I looked online on how to install the flex cable and everything from how to disassemble the phone to installing the new flex cable and reassembling the phone was right there! I followed the instructions and I installed the new flex cable and the phone is as good as new!!! Both screens are working and I didn't loose any pictures or contacts from the phone!
All it cost me was $5.00 and about an hour of time! It even came with free shipping! Go to google and type in Motorola v3 black screen and look thru the solutions. Some of them will explain how to disassembe the phone and replace the flex cable with detailed pictures! You can buy the torque screw drivers at Home Depot or on ebay! Good Luck!

Yup I agree.. I have the same issue going on with my Hubbys phone right this minute.. I have a Flex cable on the way for it.. Just the Keypad is lit on mine.. But the Flex Cable is the one cable that controls the LCD the side buttons and the key pad and yes its the cable you see running in back if you take the battery out.

hi there.
the problem your having is caused by a ribbon that connects the screen and the mainboard in the phone.
the ribbon seems to have either come loose or detached.other than that being a problem it will almost certainly be a screen issue where the lcd has burnt out.
but in my professional opinion it will almost certainly be a ribbon issue

1), remove the bottom part (completelly)
a) do you know how to open the bottom part?


2) remove the cover on the top part
a) disconnect the keypad LCD Flex Cable

3) remove the two chrome "big screws" that allows it to open and close

4) CAREFULL!!!! WHEN YOU READY TO SEPARATE THE TOP PART FORM THE BOTTOM!!
a) make sure the Flex cable is loose, and take a screw driver, push the ping on the other side (try to do this at the edge of a desk or table) keep pressure until this side pops out. KEEP IN EYE ON THE OTHER SIDE!! that the Flex cable does not get cut out by separating the two sides.

5) Replace and pop the two sides together.

6) Put everything back together.


Good luck!
let me know if I need to be more specific

On a RAZR, there is a problem in the joint or hinge where the phone opens, and the flex cable that connects the two often comes loose. This can usually be fixed short term by pushing the halves of the phone together firmly, and then opening and closing the phone. Do this while the battery is out.

For a long term fix (or if that doesn't work), you have to take the phone apart. It would be best to take it to a repair shop for this.

try reflash the phone or replacing the lcd

hi, Check if the external display working fine, also try to unfold slowly and see if anything comes to the display,coz this is normally the problem with display change over switch. all the best sreejith
