Since yesterday my MX2 LK-202-24 USB Rev 1.5 is dead . The LCD does not power on from usb cable but it does if i connect the floppy power connector.But it does not end here. If i power up the LCD from floppy power connector my PC does not recognise the LCD. I have tried this many times in two different PC. Could this be faulted hardware? I have nothing connected on the LCD (outputs,sensors). I have purchase the LCD about 4 months ago.
