Hi all,
I am working on a Kenwood CS-2150 oscilloscope with a fault in the power supply (I hope it is NOT the flyback!). It generates a high frequency noise, coming from the flyback, but all voltages are low and, if I leave it connected for a while (just some seconds), something starts to get hot, as it smells a bit...
So far, I have found and replaced a couple bad transistors on the PS section.
Of course, I need to investigate further but have no schematics nor any other service info for the unit. I think the CS-2100 has a similar power supply. I wonder if someone could have the shematics and/or service manual for any of these units.
Thanks a lot!
