My dsc-h1 bought in 05. I am now unable to access the menu, zoom, change view finder, macro, change flash, ... well you get the picture. I have tried to power boot.. holding power button for 30 seconds and no go. The sony tech was stumped. I can use my dial to access the pre-adjusted settings but not the main camera settings. New batteries, memory stick good, and it worked fine 2 days ago with no trauma to the camera since the last use. Any suggestions?
