Re: Tries To Come on, But Screen Will NOT Light Up!

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

Re: Tries To Come on, But Screen Will NOT Light Up!

Replace Motorola V3 RAZR Keypad flex and Left Knuckle...

Need a small flat tip, T3, T5, and T6 torx screwdrivers. Remove battery cover and battery. Remove two T6 screws holding the main board cover in place. (will not need T6 anymore for disassembly). Lift gently where battery contact terminals are. Will expose where main Keypad flex plugs into main board. Genty unplug this flex with a small screwdriver. (CAUTION, THERE ARE SMALL COMPONENTS ALL AROUND THE PLUG ON THE MAIN BOARD - BE GENTLE!!!) Once the main flex is unplugged, gently work the back housing piece and main board until it releases from the phone. Set this aside. Looking at the back of the phone now, there will be a total of 8 metal tabs. Two at the top (under sticker), two low on the sides, and then two on each side of the phone under the label. Bend these straight up. This releases the keypad cover, exposing the keypad flex.

With the phone open, looking at the main inner screen, 4 rubber bushings (1 at each corner) cover 4 T5 screws. Remove the bushings and the screws. Close the phone to now be looking at the outer screen. Start at the top, by the camera lens and gently work off the outer cover. With the screws gone, it is just snapped into place.

This will expose the upper flex connection. It will be on the top left if you are looking at the outside screen with the camera on the top. The camera will plug in on the top right. Unplug the main flex and the camera. Remove the camera. (should pull straight out when unplugged. Remove rubber cushion under camera. There will be a small thin metal piece on the right side of the whole the camera was in, remove that.

With the main flex unplugged, looking at the top left of the closed phone, you should see the ears of the left knuckle (chrome) if it is broken, you might not be able to see the whole thing and pieces might fall out. Using the flat tip screwdriver, push this piece out of the left side of the phone.

Turn phone back over to be looking at the sticker in the back of the phone with it closed.

T3 screw in left side top, remove. Hinge grommet should come out relatively easily exposing the tip of the spring loaded hinge. Hold the phone open at a 45 degree angle and depress the tip of the spring loaded hinge. When it is depressed far enough, you should be able to work the top and bottom halve's of the phone apart. Put the top half aside.

The bottom half is now ready to remove the keypad flex. It is held in place by some pretty decent adhesive. Look very closely at how it is mounted into the housing, how the plugs run through, etc. If you are sure the keypad flex is damaged, you can just rip it off. If not, go very slowly pealing it up and working the plugs through the housing. One small tear can kill it.

Keypad flex and left knuckle can be found on ebay. search for...

Motorola RAZR V3 keypad flex
Motorola RAZR V3 Hinge set, or left knuckle, or left hinge.

Follow steps in reverse for reassembly.

Screen stopped working today. phone rings but I can't see anything on the screen Can I fix it?

Richard, Brad Brown may be right .The screen on your phone has a back light,invert er board.
Just like a laptop screen, once the back light breaks or becomes faulty no images can be seen. Try links below, for some possible fixes, before you give up on it.

My motorola v557 cell phone doesn't light up. how


there is nothing wrong with your screen, the problem is from the flex that connects your screen to the phone's main board. This flex must have worn out that's why your screen is not displaying any picture.

The problem is common with flip and slide phones. The flex gets worn out as a result of constant opening and close of the flip or slide phone.

I would urge you to replace the flex and I am assuring you that your screen will display picture again. You might also be lucky to find out that the flex is not well fix, that is, it may have loosed contact.

If you cannot change the flex yourself, maybe you should take the phone to a local repairer within your vicinity, so that the flex can be fixed/replaced.

Good luck.
