The internal screen on my LG Env Touch remains blank after opening. The interenal keypad lights up when opened, but not the screen. The phone did not get wet, to my knowledge, and was functioning properly...

Hi, most screen problems usually happen after a fall or a knock against a solid object. There are two things that might have happened here. One might be, the screen got a hairline crack and the connection to the lcd is broken. The other is that the lcd did not crack, but the connector flex cable is disconnected. The first requires a replacement lcd. The second requires an inspection to see if the flex is disconnected or broken. (You will have to open the phone). If you cannot DIY, then take it to a repair shop. Replacement lcd can be found on ebay.

Motorola RAZR V3 LCD SCREEN went blank - black screen

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.

Razor v 3 keypad will not light up,everything else is fine

Hi,keypad light issues for Motorola phones are usually caused by the flex of the phone and also the Keypad IC.

The flex of the phone is located inside the phone, it controls the functions of the screen an also the keypads of the phone.

The flex is a thread like object that is located inside the phone. To see the flex, you will need to disassemble the phone to get to the flex of the phone.

After replacing the phone flex, your done.

Also it might be the screen of the phone. But in other to know if it's the screen, you will need to test a new flex.

You can get a replacement flex from any of the phone repair stores around you.

also When buttons on a cell phone does not work , it is usually a problem from the Board of the cell phone. An IC problem...

IC are small chips that has different functions on the cell phone. Each IC chips on the cell phone has it's function. The IC controlling the function of the keypads npt working is damaged and needs to be replaced.with another IC chips.

You can get IC chips from your mobile company mini office or you can simply go to the nearest Expert repair store around you area to replace the damaged IC chip that controls the key pad not working.

Sometimes, it might just be dirt or water spill that is making it not to function. You can open the cell phone and clean the keypad area,

Hope it helps.

Thanks for using fixya...

your screen dosnt display anything?I am not quite sure what your asking but ill take a crack at it changed the housing and when you put the phone back together the lcd stoped working,if this is the case you either disconnected your lcd or you damaged the flex cable to the lcd,either way you need to open your phone back up just the top part where the lcd is,you should beable to see the flex cable coming from the phone to the lcd if it looks connected disconect and reconnect and try it if this does not work you may need a new flex cable wich means that you may have to get a whole new keypad cause the flex cable usually only disconnects from one side,well good luck
