Come to the ETF convention and have somebody show you how to use one.
They could have a workshop.
A calibrated scope is THE #1 tool for TV service. Second is a resistance-capacitance meter. Voltmeters (preferably analog) are third, since many charts list DC only and
its not always easy to figure out the DC average from a calibrated
scope trace.
A multimeter will, however, be used much more than an UNcalibrated
scope, which will still solve TV problems quite well.
