Re: MY TV is dead!
There is a install kit 483531057673 for this model when the set is dead. The kit will contain 7404 and the Horizontal Driver Transformer 5402 along with resistors that will limit stress on 7404 and includes complete instructions.

First, you will want to isolate the problem. Is it feedback from an AC outlet you have it plugged into? Is it a recent noise that just started with no changes to Tv or its environment, then you may want to consider that a circuit is going and decide if it is worth repairing, You should find that type of fix at a shop for under $100
The TV was making the clicking noise and not turning on because an internal error was being detected.
Now things had got worse , and something had blown inside the TV.
The burning smell and high pitched noise is coming either from Flyback transformer or PSU board. Repair is a delicate matter and must be done by a technician.
This is an issue with one of your power supplys wether it be high voltage horizontal power supply or the reg power supply. The beeping noise is letting you know that it has some power but not enough to start the high voltage needed to create the picture on your tube. I would seek professional help for this issue.
You have a problem is in your horizontal section which also is part of your power supply. The high pitched whine is from the Intergrated High voltage transformer (also called the flyback transformer). This sound occurs when the freuency of the transformer changes and or the voltage gets too high. The click occurs as a result of the drawing of excessive current by the HOT Horizontal output transistor. This is repairable, but requires the correct equipment and a schematic.
There is a coil in the set with a magnet glued to it, called the horizontal linearity coil. Sometimes the coil "sings", making a squeeling sound. I have seen this many times, and there really isnt anything actually electrically wrong with the set. To stop the squeeling the coil should be replaced.
A high pitched whine is most of the time the power supply trying to run, but it is being loaded down from a short somewheres in the set. Sometimes a resistor on the CRT board will open and make the set shut down right after start up, sometimes the horizontal output transistor causes this problem, almost any circuit for that matter can cause this problem. Good Luck
That high pitched noise you're hearing is the power supply telling you that it has too much of a load on it and lowered its operating frequency which in effect cuts its output way down! Normally you don't hear any thing since the power supply operates at a frequency that's beyond human hearing.
In an RCA this indicates more than likely that your horizontal output transistor is shorted and this short was caused by the flyback transformer shorting. This is a common happening with RCA's
You'd need to take to a tv shop and have it checked out.
