Hi;
My oscilloscope screen will lights up momentarily and then the screen will be dead blank. I suspected the problem is from the protection circuitry A6 board. But the fluke service manual really sucks. Not at all clear with its description. I just broke the feats...really!. the manual say to pull it out, so I did and crack the feats....LOL.
Anyone would like to advice me how to dismantle the A6 board. Cannot see any clips or screw holding it onto its slot. What would likely be the problem? opto?, diode?. The fans would rotate couple of turns before it went dead every time I press the on button. Even the fan connector cannot be pulled out.... Now, is there a clip somewhere?
I would also like to clean up the fans, replace it maybe... How do you dismantle the fan.... its not even described in the service manual...
thanks for any help rendered...
