- MOSFET needs a turn on pulse and a turn off pulse as gate capacitance is huge.
- NTSC is like 320 x 240 pixels, which is TV, which is lower than your computer's 800 x 600.
- Do not use an oscilloscope to measure 230V directly, use a transformer, differential probe or attenuator.
- An oscilloscope 1M probe or a DMM 10M impedance can load circuits with nano-pico amps of bias.
- Red socket and probe for positive and black socket and probe for negative
- In schematic indicate pin numbers of every IC or map the correct part if manual place and route is used.
If the waveform on the scope droops then you may need to use a 10X attenuating probe or mode. this attenuator is at the tip of the probe hence better measurement possible, also very high frequency signals may be best transmitted over a 50 ohm impedance matched line to the Oscilloscope.

Is it oscillating ?.... We cannot say, it could also be DC, you need to see if a Clock is present. use a signal tracer or a DMM freq mode, or AC measurement. or build this solorb.com-elect-logprobe. When you do not have a scope you can build one for the PC.
