I have a camcorder HDR-CX360VE, on the first time of trying to use the flash this error code E:91:01 appeared. The flash did not work, it just made the battery charge light flash but the error code has flashed ever since. The camcorder is out of warranty by about 6 months. As the flash is not always required, I had never used the flash within the warranty time. I have now found out from a worthy source that this is a manufacturing fault and to put it right will cost in excess of £120 plus any carriage costs. As this is a manufacturing fault surly this should be paid for by Sony?
