Hi Timmy,
Here is the zoomed section of the TR-1010P's vertical scan section.
From reading the posts above, i understand that you don't have an oscilloscope, correct?
Have a friend, a contact at work or a neighbour that would have a scope?
Personally, i would try the following method:
V Scan energy is at 60 Hz. As power is needed to deflect the beam it generates a quite powerful magnetic field.
Do you have a telephone amplifier with a pickup coil?
do you have a small audio Amp, i'm thinking of a 1W battery powered amp with a small speaker?
My idea is to use a makeshift system with a pickup coil and an amplifier, placing the coil next to the TR-1010's deflection yoke and listening for a strong 60 cycle hum.
As the CRT shows a flat line (no V Scan) i suspect that you will not pickup a strong 60 Hz signal, but the gadget can help you while poking around in the V section, maybe you have a cut trace, bad deflection yoke connector, dry solder joint, or even a bad new capacitor.
Just a Rube Goldberg device, but it's helped me out frequently.
I used a tel pickup coil + a small cased Amp i found at Radio Shack (years ago).
Good luck!
Best Regards
