I had a 700w laying around with a good screen. My daily 700w treo had a crack on its lcd. I wanted to swap out screens. I did so, and put it back together. Now I only get a black screen when the phone powers up. I replace the replacement screen with the original cracked screen and even that one now gives me a black screen. Have I missed something??
Yes, most likely you have missed the proper technique of installing the ribbon strips correctly into the connection block. I did the same thing and it took me three tries to get it right... I stumbled on this by playing with other ribbon strips on the phone that I could access better and found that there is some sort of “step” or “threshold” inside of the connection block that makes you feel like to have "seated" the ribbon strip at the bottom of the block when in fact you have to push harder to actually push the ribbon into the block fully and make contact with the connectors, and then snap the locking bar down. It's an easy mistake to make since the connection block and ribbon strip for the screen are hard to get hold of with your fingers... try using some tweezers or small long nose pliers to hold the ribbon and seat it fully. Now I still am trying to figure out how to unlock and install the touch screen ribbon into the connection block… it’s really small and does not seem to what to unlock to allow for a full installation of the really small ribbon strip and lock it in, so I used a piece of duct tape to hold it in place and it works fine… not my perfect fix on this one, but my ph works… Robert R.

1. Disconnect the Treo from a charger or USB cable.
2. Remove the battery cover and take out the battery.
3. Press and hold Power/End while you insert the battery.
4. When the screen lights up with the logo appears, release Power/End.
5. Press Up when the Erase all data? prompt appears.
6. Press Up to confirm the hard reset.
The computer doesn't know if you have made changes or not... until it talks to the device... so, instead, how about shutting down ActiveSync or changing the connection settings so that it can only sync when you want it to.
I was able to find many parts for my 700w on ebay including keyboards. You should be able to find what you need too and the keyboard is a sinch to remove and replace onew you have the two needed tools to open your phone, the T-6 screw driver and a cover removal tool that help unsnap the cover which is a bear to do without the tool. Do an ebay search to "Treo Cover tools" or "Touch screens for Treo 650" and you should find all you need.
