Troy, I've been there several times. For some reason, some versions of the QHY5 circuit board do not have any write-protection on their CMOS chip and they tend to get scrambled. There is a routine for reflashng the CMOS and this has worked for me two out of three times. The third resulted in a dead camera. There is also a method of DIY modification to the circuit board which write-protects it. The way you tel which version of the circuit board you have required you to open the camera. You remove the sponge/foam protection around the sensor to reveal the surface-mounted components below. If you can't find the details let me know. Probably have it hee somewhere.
