Most people know what spark plug wires look like, hopefully you do to. You should see some red wires inside your set that are thicker than all the rest of the wires in there, these are carrying your high voltage. The component on the main board with only one of these wires coming from it, is your flyback. It feeds into the splitter, which should have about five or so wires running into it... visually inspect for burns or sparking, that is usually a good sign something is bad in the high voltage. Anyway, if you check out the post from maierTV about ctc169 chassis, there is a good way of testing your splitter listed within that post (which they have made several times over)(it may not be your chassis # but still might work for testing HV Splitter). I would start with that, but once again, these are really high voltages around 30,000 volts, and there is also the 120v from your outlet that wouldn't mind getting a piece of you too. Whenever servicing a TV it is in the best interest to have an isolation transformer to help protect yourself. Is your life worth less than the service call could cost? Just pay the 60 bucks, but make sure they give an estimate, then if it's not worth it, buy a new one or at least they will have told you what was wrong, and then try the repair yourself.
