I have a suprima which is causing me a bit of trouble. It was randomly locking out before and sometimes both LED's were going off on the original PCB. Whenever I went to look at it, it worked fine but my customer was just reporting when it failed etc. I replaced the PCB with the new upgrade kit with wiring loom etc. Now a week later I have just been told its stopped working again. I haven't seen it yet, but apparently the red light is flashing fast and then going solid red. Any suggestions on what to check first?
