Hey all,

Thanks in advance for any help on this. I'm a high school physics teacher and I came across this device in a surplus warehouse and I'm hoping to get it working if possible. It is a wavetek brand waveform generator model 75.

the device turns on but the LED display panel is all black blocks and no digits. I've read the manual and tried the reset procedure of hitting setup 3 times, then f2 and then f3 but there is no response even during this process. I have measured the signal from all of the outputs and no response.. I really hope this is a common problem and is fixable, this would be a very meaningful device for my students in our classroom.



has anyone had experience with this problem on this or a similar device before?

thanks!
There don't seem to be a service manual up front, I didn't fully look


You didn't look at all. The first hit on Google provides the
manual:
