I'm stcuk in front of a "frozen" DSO1024A in the dual trigger mode.
No matter what button I push, if I turn the scope ON and OFF and ON or unplug it it remain frozen.
The values around the monitor are displayed ( trigger, sensivity ... ) but no trace are on the display.
No matter what button I push, the keyboard is dead.
Any way I kick it back to life, some type of BIOS MASTER RESET ??
( The bios is up to date, it's a new acquisition and had been running perfectly for the last 5 month )
It's probably something like a stuck button, or a loose cable. Resetting the BIOS probably won't help, since that happens on every power-up. Did the scope work at one point, then stop? If you shake it, is there anything loose inside?
I would suggest some light to moderate "percussive maintenance". If that doesn't work, a repair is in order.
