Like I have said I really don't know what I am doing with the scope yet for sure, but Nomad helped quite a bit here, I turned down sweep time/ div to 2 and put the probe on pin 2 on that ic I had replaced and the line rises but I really don't think it really shows a waveform I don't know. The first picture is with the probe off and I had set the line to 0% at the bottom. The second photo is with the probe on pin 2. Perhaps I need to make adjustments

From what I can see you do have a signal on pin 2. I just can't say if it's any good or not. It should be in the neighborhood of 4 MHz or so. Or at least that's what the service manual says.
I went back in the thread and found where the schematic and some service notes were uploaded, but not the service manual, so I'm attaching that here. It can probably answer your questions faster and more accurately than I can.

Forgive my ignorance as I have never had the pleasure of owning an analog scope (cool!), but what is with the bright and dark bands? Is that persistence from the phosphor or a camera artifact?
Why not adjust the horizontal scale a little to try to see the rise and fall of the actual signal? It is clear there is an AC signal there, but it is not clear what it is.
1/frequency=cycle period. If you expect to see a 4MHz signal, set the time per division close to that period so you can see whats happening.
Did you calibrate your new probes?

Yeah, I am new to using a scope and I need to work with it a bit and do some research in them, I will try your adjustments and also look into how to calibrate the probes because no I did not calibrate them yet. Thank you for the advice I appreciate it, this is a new ordeal for me
