Re: How to troubleshoot a faulty 7B92A?

Thierry Delaitre

thank you.

The 7B92A is still in the vertical slot.

Regarding pin 7 and the TRIG'D light, the light is off when the scope gets switched-on (with AUTO, AC, INT). The TRIG'D light switches on if i change the mode to NORM. The light stays on if I revert the mode back to INT.

Pin 10 remains at a constant DC high voltage and Pin 8 remains at a constant DC low voltage. both pin 10 and 8 do not show any visible waveform

I use a scope probe on the same scope to troubleshoot.
