Of all the sets I've had recently, only one has worked OK without changing capacitors. You can't just keep plugging these things in and expect that they will work OK. Or check old caps with an ohmmeter and think they are good. Even if it does work, it usually won't for long and you will end up frying flys or other expensive parts. The noise you are hearing is your flyback screaming for mercy. Back in the day, there were TV/Radio repair shops everywhere because these things broke down. Especially if they have been sitting for 40 or 50 years. The first step in learning how to repair them is to learn to change capacitors.
ive had a lot that i got working without replcing caps
