Thanks for your reply. No I don't know how to troubleshoot a vertical
circuit, but I'd like to know how.
I have a voltmeter, but I assume I need more than that. What do I
need? I would like to be able to do troubleshooting so I would
consider buying more test equipment..
I don't have a schematic, so I don't know where the vertical circuit
is. Would it help to have one? If so, where can I get one?
I would expect I could buy a new 25 inch TV cheaper than I would pay to
repair this 20 inch one; so it's either fix it myself or throw it out.
