    I happened to fall into a lake with my phone in my pocket, and I have the same problem, it just flashes as though it is about to start up normally, then it turns off, and repeats over and over...

    when i go and turn on the phone or plug in the charger, the screen just flashes. The odd thing is, I didn't do anything to the phone. I just turned it off at night and wouldn't turn on in the morning.

  • OpenAirwaves Feb 04, 2009

    Yeah. The small front screen flashes between the vCast screen and black, while the main screen flashes between black and white.

    Mine is doing the same thing. I was at work using it as usual and then all the sudden it started flashing the vcast screen. What a shitty phone.

    i have the same exact problem!! i just got my replacement phone yesterday (the one before got stolen) and this morning i was texting..and then my friend was playing with it and it started saying "intial programming needed" and i was like wtf..i already activated then i opened my phone 10 minutes later and the screen was black and it said "downloading file" and "image cannot be seen" so i tried turning it off but it wouldn't turn i took out the battery..and i tried turning it back on and now the v-cast thing comes up and then the screen turns black and it just blinks...i have to take the battery out so the screen will stop blinking..

    my friend said that it might be because i over charged the battery..cuz it said to charge for 12 hours..but i charged it for like 15 hours..and that shouldn't make a difference..but she said that her dad had a verizon phone and the same thing happened..and the lady at the verizon store said that he overcharged his phone..and she pushed some buttons and it started working..

    My phone flashes vcast and one time locked on problem at usb bootblock message. I tried several things like removing battery, holding end botton, plugging in charger and and holding the lock botton. There has no water damage or major drops. The crazy thing is i was using 1 hour before the problem was noticed.

  • irishtaylor3 Mar 30, 2009

  • dksam May 22, 2009

    Turn it on, all it does is vcast flashes off and on. When flipped open as a phone, just says 'VCast'. When flipped open for texting, says VCast Phone'.

Same thing here... got caught in the rain, and now it just goes on to the V-Cast screen and flashes.  Removing the battery does nothing.  Tried a blow dryer to the case (didnt disasemble) but this had no effect.  Any ideas?

This happened to me when I put the battery in backwards. When I slipped it around so that the "samsung' is on the outside, it powered up just fine.

Turn on, all lights flashing, can't turn off unless i unplug printer

It's highly likely that your printer has reached the "service required" point but I couldn't be 100% sure.

I'd recommend downloading the SSC utility from SSCLG, get that installed and then follow the instructions for configuring to your printer model and resetting the protection and overflow counters.

If that works you'll then want to be thinking about cleaning the waste ink pads or installing an external waste kit.

If it doesn't work you have bigger problems and need to describe the flashing patterns and any other symptoms in detail.

Hope that helps.

Get pictures and video off phone to the computer

Preparation ? if an external Micro SD external memory card is to be used as the desired music/video/picture repository on the W755, install the card in the W755 behind the battery. Then go to SETTINGS & TOOLS ? MEMORY ? CARD MEMORY ? FORMAT and format the new card. Caution: reformatting the card will wipe out all contents on the SD card. Download/install free Motorolla Handset USB Driver Installer onto the PC (execute ?.msi? file). Download/install free VCast/Rhapsody software (no need to actually sign in or use the proprietary Rhapsody service). Start the VCast/Rhapsody software. Turn on cell phone (works with W755 and may work with other Verizon ?music phones? such as LG Chocolate, but the latter was not tested). Connect phone to PC ? connect USB cable to PC?s USB port first, then connect USB cable to phone . Be patient, it may take a minute to fully ?connect? in the phone?s display. Go to ?Sources? section of VCast/Rhapsody GUI screen ? the phone will register as a directory title using a name roughly like ?VCast xxx.? Windows Explorer will also show a ?VCast? drive/directory device. Files can be selected and dragged to and from source and target directories. At this point various options exist regarding music, picture, video management: 1.) The VCast/Rhapody software can be used to manage music, picture, and videos between the PC and phone. Again, no need to use the VCast service, just the software offline. 2.) Alternatively, other music management software such as Media Monkey (a personal favorite) can be used to move music, create playlists, etc. ? NOTE: Leave VCast/Rhapsody software running in the background as a means to ?connect.? It is best to start VCast, then plug in phone, then start other media management software so that the media management software will benefit from the connection (usually with a directory name using some variation of ?VCast.? Then use the alternative media management software as usual. Please note, this is a generalization based on success using basic software like Media Monkey, for example.

My samsung sch740 cell phone

my phone wont let me hear anything when i call people or when people call me anyone else having this problem?

Sounds like he has the older version of software for the 8300
go to settings and tools , phone info ,SW version and see if your sw version ends with vo2, vo3 or vo4 .vo4 cripples some functions , v03 is the best in my opinion and vo2 is limited version also . unless it is vo3 take it to your verizon service center and talk to someone real nice and get then to flash it back or up to v03 , will take them about an hour to finish it.
you can also
Try pressing
then the service code
then scroll to music setting click ok and see if the option to turn on mp3 playback is listed.
