I switched on my HP54610B scope today having not used it for a couple of years. The fan started (possibly a bit noisier and a bit slow but I¡¯m not sure), and the display remained blank, even after turning the brightness to max. It worked fine previously. I have downloaded a manual to start troubleshooting it, but before I start that I thought I would just ask if anyone is aware of any common/simple known problems that might cause this.
