Question about Motorola Mobility RAZR V3

Dead screen My screen doesn't work, I disassembled the phone and found the integrated ribbon type cable worn through in the "hinge" area. Is this replaceable? Or is it not even worth trying to fix? Phone still "works" fine.

    My phone was working perfectly fine, and then when I got home after a long day, I just wanted to relax and text some friends, and then everytime I would close my phone, I would have to restart the whole phone. So then, I finally got into the habit of not closing the phone, it would stay open, and then before I went to bed, I closed it. And, the next morning I restarted it at least seven times, and the screen is still dead. It doesn't come on at all, I can play ringtones, and text, but I can't see anything on the screen. Someone help me, I can't get a new phone for a while. And, this one is giving me so much damn trouble. Helllpppppp !?

To replace that cable you have to disassemble the entire phone including the keyboard, screens and the lower part, then buy a new flex cable (this includes the keyboard, keyboard backlight, backlight driver, cover sensor, screen cable and connectors. all of this is part of one flex cable) and replace it.
You have a 70% chance of breaking the new cable even before getting the phone reassembled.

My screen scrambles and i can't get it right


The problem with the phone that is causing the screens scrambling is that the flexi ribbon that supports the slides of the phone is getting weak or worn out, therefore, fixing the flexi ribbon of the phone will correct the problem for you. You will have to disassemble the phone to be able to replace the phones flexi ribbon. If you are not familiar with such repairs, i will advice you seek assistance from a friend who is technically able to assist you with disassembling and reassembling the phone back together.
Hope this information helped.

Razr v3x screen suddenly won't work even with phone turned on. Yesterday it was working just fine then this morning lcd is dead. I can hear it when somebody sends me an sms but I cannot read it since...


check the oem ribbon that runs to screen. the design of phone hinge is faulty, and usually cuts the ribbon that runs up to the screen after months of openings and closings,preventing it from lighting up. sometimes its the earpiece wires on the ribbon that get cut which prohibits u from hearing anything when u hold the phone to your ear and u have to switch to speaker...bummer..sooo my friend, CHECK THE RIBBON.

How to repair broken hinge of my Verizon LG Vx8350


I was able to take apart a VX8350 I have with a broken screen. I don't see any way to replace just the hinges with replacing the whole top part of the phone including the screen. The ribbon cable from the screen runs through the hinge part into the main assembly of the phone. It appears the cable can't be removed without cutting it.

Top flip section of phone broken,


Yes you can do this but it is safe to take the phone to a mobile repair shop and have them repair it for you.

Remove battery cover and battery. There are four small screws visible on the rear cover, remove those. Wiggle and distort the back cover a little at the bottom of the phone until it pull partly free from the phone, slide a guitar pick or small flat blade screwdriver between the phone and the rear cover, at the side of the phone, pry this cover off until it snaps free. You will see the main board now. Remove the two screws holding this board on, carefully fold it back towards the battery area. The main ribbon cable is visible now. Remove a green tape on the socket where the ribbon cable joins the board. pull the ribbon away from the board gently and use a screwdriver or something else to cut the adhesive between the board and the cable. The socket has a hinged brown piece closest to where the cable comes in, that flips up to release the cable. The small cable coming from the number pad is removed by gently prying up the rectangular connector from the board. Now with the board free you can remove six screws from the plastic backing plate, and remove that plate from the slider assembly (one of the screws is hidden by a piece of green tape). On the front half of the phone there are six small screws on the rear side (the camera side). Four are visible, two are hidden behind rubber plugs at the top of the phone. Separate the chrome trim from the backing plate by starting at the bottom of the phone, by the key pad, and it may be stuck from a little day-to-day dirt but separate it there, then swing the bottom end out and release the front cover from the two clips that hold the top end together. You now can separate the ribbon cable from the screen assembly in a similar way as you did with the other end of the cable. Reassembly is the reverse of disassembly. Be sure to replace the pieces of tape, and the wire mesh shield attached to them, they serve to prevent radio frequency interference between parts of this device, and between this device and others.

Good luck, and happy dreams.

See my solution posted on 30Sep. Open phone then press/squeeze between camera lens and vol up/down switch. That is where the ribbon cable is located. This will reseat the cable pins. The ribbon cable works itself loose in this area when the phone is opened and closed. This procedure will usually reseat/straighten this ribbon cable.

Your flex cable has most likely gone bad. If the phone is under 1 yr. old I would suggest have it repaired by a warranty repair facility. If you are going to try replacing yourself let me know, I will try to help w/ disassembly. Good luck.
