Hi,
My tr3a webcam is also died (white screen), while i did not serve more than 4 hours in 3 years!
I recovered last week a webcam from an acer 3100 aspire laptop (produce of bison or logitech, I don’t know actually). It seems possible to put in in the tr3 cam box : it’s an unique board which dimensions are smaller, there are:
1) a flip flop switch to reverse the cam,
2)a miniusb 5 pins connectors
3)fix focus lens
4)a green led on the right of the lens.
(surprisingly the usb connector on the board cam has 5 pins and the usb cable has only 4 pins)
Apparently, just have to recover the focusable lens on the vaio, move the green led to the left, cut some plastic and fix all with some glue.
I didn’t have the time yet to search the driver to try this webcam, if it works I probably put it in the TR cam box. I think that the resolution is 1280 x 800 pixels (data found on ebay), thus better than TR. I will tell you all probably next month.
I think that the ideal is to find a laptop cam part who has a flip flop switch, which is not the case of the EEE pc.
