I have an old Tektronix 3347A 100 mHz scope with an control problem.
Power-up is OK and runs fine for about 5 minutes then all buttons become
inoperative (all lighted buttons go dark) but CRT display is fine.
Anyone know of a website with ideas for this scope?
Thanks!
While I'm not familiar with that series, by the description of the
problem I'd start my search at the power supply.
