Re: Dead phone I think????

This cannot be a software problem; it is a loose connection from the phone itself to its LCD. if you press the screen it should flicker back and forth. I am having the same issue; I of course, did not buy insurance on the damn thing. Does anyone know how to open this thing up to play with the connections? I have basic knowledge of electric devices the problem here is opening it without further hurting the already ailed phone. Suggestions welcome.

Phone got wet in salt water-let it air dry for 4 days-sim card ok-top screen works-when flip phone open-other screen lights-up but is blank-can't pull-up menu-when put battery in-phone...

Take the phone and place it in a bad of minute rice....the rice will pull the remaining moisture out of the phone... however the corrosive nature of saltwater may have left deposits inside the phone that are causing it to may never work correctly again... but try the rice before giving up on it...even the rice may take a few days to work...

My samsung screen is white but it works ive tried everything, this hbas happen before screen going white and the battery had to be without juice to come back. it works but ithe screeen is white

hi, the main reason the screen turns whits is due to the thin ribbon that sends the data from the circuit board to the screen being damaged what happens is that the thin copper wires that are inside the ribbon ware and then break causing a short to the screen and this is what turns the screen white. this happens on most flip and slide phones as the ribbon moves when you slide or flip the phone so over time it becomes brittle and you lose the connection and this turns the screen white.

sometimes it will right itself if you open and close the phone a couple of times but this wont be a long term fix how ever it may be that bad that this will no longer work, its not expensive to get this ribbon replaced but taking you phone to a small phone shop would be your cheapest option.

When you flip phone open inside screen stays white

Moto RAZR phones are notorious for this. Best thing to do - Get a new phone. Inside of the hinge, there is a sensor that detects if the phone is open or shut. When you open the phone, it still thinks its closed, so the screen stays white, and if im correct the outside display should still work. Pretty much not-fixable unless you know someone who can take it apart and re-position the sensor (will void the warranty)

Best thing to do....Upgrade.

How do you change the faceplate on the nextel i95?

BASIC disassembly of your phone(i60/i90/i95)
This ONLY covers unscrewing the housing and splitting it open? that ALL. You'll need a T-8 torx driver for this.

Step 1: Turn you phone off, turn it over, take off your battery cover, take out your battery, and take out your SIM card. Be careful with your SIM card. Unscrew your antenna, remove it, and take out the metal antenna tube.

Step 2: Get your T-8 torx. Unscrew the THREE torx screws in the battery compartment. They are located in the bottom two corners and in the top left corner of the battery compartment.

Step 3: Peel back the right hand side of your ?Nextel? sticker just above the battery compartment. Peel it back ONLY A LITLE, until you expose the fourth torx screw. Use your T-8 torx to unscrew it.

Step 4: Carefully separate the two halves of the housing. BE CAREFUL, and keep in mind that at the top of the phone (near the flip hinge) there are cables still attached (the flip ribbon cable and the headphone jack). You will not be able to separate the two halves of the phone body all the way and will want to make sure to keep the top part of the housing relatively close together. If you screw up and damage the cables up there? don't try to blame us? we warned you.

Step 5: Do whatever it is you wanted to do that required you to split apart the housing in the first place (e.g. replace a keypad, PTT buttons, etc.), put the two halves of you phones body back together (carefully aligned) and screw the torx screws back in.

Step 6: Put your antenna, SIM, and battery back in, and you're done. Enjoy!

**Now let's talk about the flip. This ONLY covers the removal of the front and inside lenses of the flip. If you want to remove your flip completely, or remove the LCD of the i90. SEARCH the forum for info on how to do that. You'll need a T-6 torx, a SMALL flat-head screw driver, a hobby knife, and a blow-dryer for this.

Step 1: _This is optional, but is ideal for those nervous people out there who don?t want to take any chances. Remove your antenna and battery but put your battery cover back on.

Step 2: FIRST, open the flip. With the phone facing you (as if looking at your screen), look into the gap between the flip hinge and the phone body in the very center of the flip's hinge. You're going to see a small slot in there. Remember that slot? it's important.

Step 3: Close the flip and turn on your blow-dryer. Keeping the dryer about 4 inches from the surface of the front lens (the blue thing on the i95 or the silver thing on the i90) heat up the lens surface. Keep your blow-dryer moving around? DON'T concentrate it in one spot, you'll end up melting something. All you want to do is soften the glue a little. You don't need to use the dryer for too long to accomplish this. A minute or LESS should be fine, use your GOOD judgment.

Step 4: Once you have heated up the front lens enough to soften the glue underneath, quickly open the flip and use your small screw driver and poke it through that slot we talked about in step 2. You are pushing on the back-side of the front lens when you do this. BE GENTLE! You should be pushing the top of the front lens away from the top of the flip. Manipulate the phone in your hands as necessary so that you can hold the top of the front lens away from the phone. Remove your screw driver and close your flip (careful not to let the part you pushed away slip from your grip.)

Step 5: GENTLY pull the front lens away from the flip a little bit and use your hobby knife to cut away at the glue. BE CAREFUL not to knick or cut ANYTHING EXCEPT for the glue when you do this. In this process you will cut a little, and pull a little further away, cut a little, and pull a little further away. Continue this until you have completely removed the front lens. Once completely separated, make sure little to no contact is made with the glue on the back of the lens or the front of the flip. The more you touch it, and/or the more **** that falls onto it (dust or dirt or whatever) the less sticky it will be.

Step 6: Use your T-6 torx driver to unscrew the four torx screws on the front of the flip. These screw hold the inside flip lens down, so once they are out, be careful when you open your flip.

Step 7: Open your flip and gently remove the inside lens. BE CAREFUL. On the i95, the LCD is NOT glued to the inside of the flip. It is held in by the inside flip lens. You'll need to GENTLY remove it from the lens. If you're not careful.. you'll damage your ribbon cable and be screwed.

Step 8: Once your done doing whatever it is you wanted to do that required you to take your lenses off in the first place, just reverse the processes in step 7 and step 6 to attach your inside flip lens again. Then simply pres your front flip lens firmly back in place. If you were careful, the glue should be undamaged and would be PLENTY strong enough to hold your lens securely in place. Presto, you're all set! Enjoy!

Blank or White screen on new Motorola Krzr k1 cell phone

found the solution to the white screen! it's the flip sensor.. what you have to do is open the phone hard and fast... make it so when you flip it open, the sensor knows when to turn the screen on and off.. this may take up to 5 or more times.. jus keep opening it hard and it will eventually work!!!

V3 problem

There's a small magnet in the flip that tells the phone that the flip is closed.  the sensor in the body of the phone is still thinking that the magnet is near it, so it thinks the phone is closed.  if you don't have any magnets near it (a phone holder with magnet closers, cover, etc) then it'll need to be repaired.
