Dear tektronix fans
To introduce myself Hubert ON6JZ living in Belgium and an electronics repairer for 45 years
I now have a tektronix 2712 on the table that does not work.
It has been idle for over a year.
At startup it gave all kinds of error messages , after replacing both batteries on the digital board and on the digital option board it seems to start up normally ,
but I get no response from any button and the encoder does nothing either
All supply voltages are correct and viewed cleanly with a scope
I replaced all the smd electrolytics on the sweep board and on the digital storage board
No result
On the screen I get an image of out of memory.
Does anyone have any tips on where I can look for this error?
Thanks in advance
Hubert
