Tektronix T912 Sillyscope,
Plug it in,hit the power button,fan comes on,power indicator light flickers,no
other signs of life. Get a flash on the screen on power-off.
My "What could it be" question might seem vague,but I was just given
4 of these scopes and they all do the same thing.The fella that gave them to
me has 4 more that do the exact same thing.He bought them new in 79-80.
So,here we have 8 scopes with the same symptoms,that is what led me to think/hope there is a known failure issue with this model.
I downloaded the schematic,but have not had a chance to open one up yet.
I am hoping some "back in the day" tech might remember this model and recall
what the common failures were.Thanks for reading this........
