The first thing I tried was the soft and then hard resets. When I returned home I plugged it into my computer, and was able to connect with ActiveSync, but I couldn't get past the touchscreen setup (caused by the hard reset).

I removed the battery, removed the back plate, removed the slide and keyboard, removed the LCD/keyboard/camera connectors, cleaned the contacts with alcohol, reseated the connectors, and reassembled everything.

When powered up, the touchscreen still didn't work.

I downloaded the latest official ROM upgrade from Sprint, connected via ActiveSync, and ran the ROM upgrade. I went to get a pizza for dinner, and when I returned the install had finished and the phone was at the screen setup. The touchscreen is still dead.

Any thoughts on the next step? Does anyone know of a source for a new lcd/touchscreen?

Thanks in advance,

Its probably nothing too serious, I had the same issue and it was due to dust stuck in between the screen and the actual case. I took a pressured air dust can and removed the particles between the screen and that worked for me. Give that a try, also you might want to use something flat like a small sheet of paper and run it along the sides of the screen under the case to make sure you remove anything that might be stuck underneath.
