Hi I own a U1604A 40Mhz scopemeter (discontinued). Suddenly osciloscope's channel 2 lost it's GND, all the multimeter's functions doesn't work, means ac voltages measures lowest, all dc voltages measures 0V, resistance nothing and the beeper of the continuity test doesn't sound.

So far, I only installed the first firmware which was found in the CD and I also changed the internal battery because was 2V instant 3V.

I appreciate your help since it's a very useful instrument.
