Won't turn on - relay clicks, power supply squeals, relay clicks, etc,
The television has a protection circuit. Sound like you know something about electronics so that is cool.
I suspect the HOT or High Voltage Transformer. If you want to operate on it, they typically will short externally from moisture or plastic high voltage breakdown. The TV starts, shorts as it cannot come to full high voltage, then shuts down. If your brave, you can unsolder the HOT which is the part that is on the main board or that comes from the top of the picture tube wire into a dark or spaceship type object.look underneath, sometimes they short underneath and you can scrap the carbon and get it to at least start up and work. Do not leave this as a fix as it can be a fire hazard.
The HOT is the most common. They are around 20-60 bucks. 34" TV. I am assuming this one without looking it up it is NOT a flat screen, as most do not squeal like that nor do they have to de-gausse like the old ones. I just looked it up and yes it is not a flat screen. Old school, so that is more thank likely the problem.
