Hi, I have a faulty DSC P73 - bought very cheap as faulty - someone had dropped it and after disassembly it appears that the bearings in the lens have been badly displaced. However I want to modify the camera and remove the lens for use on a telescope. I have figured out how to mod the shutter and remove the lens and remove the IR block filter. However I need to fool the camera into thinking the lens is still OK and over come the "switch off and switch on again" message. Does anyone know how to fool the camera into thinking the lens is OK? or what the camera uses to sense the lens is OK. There is an optical sensor (probably IR) which seems to be part of the correct lens deployment detection - but I have tried various combinations of breaking the light path to no avail - any help would be very appreciated for my slightly off the wall question. Thankyou.
