White screen Im going to trade in my RAZR v3c, but in the meantime, is there some way I can get the white screen to start working again? Turning it off or removing the battery used to work, but it is being very stubborn right now.

I tried many remedies (new flex cable,cleaning connectors, new LCD board, taping the flex connectors to the board), but the issue persisted. Finally, the best solution came using a piece of toilet paper folded a few times and cut to fit. The TP acted as padding between the flex connector and the board (adding more, even pressure to the connector) and, more importantly, kept the metal piece inside from shorting out parts of the main PCB. It makes sense as often times my phone would work fine until pressure was applied to certain, seemingly random ares of the phone. Now it doesn't. or hasn't since I tried this. Also tried it on another v3c i had with the same problem. Fixed that one, too. Hope this helps someone out there. Also, this is the last time I buy a phone from eBay.

Open and close it a bunch of times. it works for me.

You can start by taking the cover below the battery off using a Torx 6 driver, unplugging the "flex" cable and cleaning the connectors. This will probably be a temporary solution as the connector most likely needs to be replaced which is a much more complicated process. If the connector is not the problem you may need a new LCD module or new flex which can be very costly especially if you are due for a new phone.
