SOURCE: Screen went blank

There is something you can try. Using a Torx 6 driver, remove the two screws located beneath the battery. Gently pry the plastic cover loose. There will be a flex cable connecting it to the other portion of the phone. Gently disconnect it. Using 99.5% isopropyl alcohol and a soft bristled brush clean the connectors on both the cable and the circuit board. Reseat the connector and reassemble the phone. If this does not work the flex cable or LCD may need to be replaced.

SOURCE: Blank Screen

Try resetting your phone thus:
First turn it OFF, take the SIM card out.

Press
* 3 send at the same time and turn phone on. Keep them pressed until the reset screen appears.
Give it time to reset.

If it works, you should update your phone software. Using Nolia PC Suite.

SOURCE: Blank or White screen on new Motorola Krzr k1 cell phone

If the phone still works, check to see if the left side of the hinge (when the phone is open and facing you) is loose. If you can wiggle the top 1/2 of the phone, the hinge is damaged, therefore damaging the flex cable that runs through it. If that is the case, replace the hinge assembly and the flex and you're good.

The K1 is no joke to take apart. Flex replacement requires full disassembly. I would recommend checking out www.wirelessunlimitedinc.com, or www.myspace.com/wirelessunlimited to have it done professionally, less than Motorola will charge you.

Or give it a shot if you want, you need a T5 Torx and lots of patience and care.

SOURCE: nokia 5130: blank screen, phone doesn't turn on

That means your phone got a corrupted software installed to its memory. A hard phone reset can solve this problem. Typically a nokia symbian series phone can be formatted using this code *#7370# then the default key is 12345.

Hope this could help.

My phone is switching on with blank scream


Hello,

When the phone turns on with the blank screen, can you receive or make calls?

If you can receive and make calls, the fault should be from the screen. Maybe it is not well connected to the board or the screen is bad.

But if you cannot receive or make calls, then I think your phone has a virus. The virus might have corrupted the phone software files, thereby, not allow the phone boot. In this case, you need to flash the phone.

Best wishes.

Blank white screen in my Acer Travelmate 5730 Laptop


Hello Karthik,
This must surely be a problem with your monitor, because you say that you see the white screen while boot up. If this is a graphic driver issue, you may have the problem after booting up in windows. Since its been only a month old laptop, the product must be in warranty for sure. Take away any CDs in the drive, any USB drives and see if this white screen appears. Let us know.

Thank you!

Motorola RAZR V3x Whiye screen problem


I have managed to fix the problem by doing a software update.
I stumbled across the solution..........I had the phone connected to the computer when I started it in the 'boot loader' screen as opposed to just turning it on. This time the computer recognised the phone was connected and through the motorola software update program I was able to update the software and the phone now works fine.
BTW I did lose all my address book, messages etc.
To start in the boot loader screen hold down the * + # + pwr keys all at once.

Blank screen


I had the same problem, so I hit the side of the Garmin a few times. It works perfectly now. Something inside was unaligned and needed a little force to knock it into place. I didn't hit it HARD.
