SOURCE: Television won't power up
It sounds like the high voltage circuit got damp and arced. This arc caused the horizontal output transistor to short.
You might try replacing the output transistor if you're experienced in this type of repair. If not then you need to take it to a repair shop.
The "whistle " you're hearing is the power supply indicating that it has a short on its load. When the power supply has an over load (short) its frequency drops down when your ear can hear it oscillating. This type of power supply is a switching power supply normally operating a several thousand hz(cycles) which is out of range of human hearing.

Check your TV resolution setting to make sure it is at at least 720p before getting into the cables. (You may have to look in the manual to find this, or the set may not permit manually setting the resolution.)
First, verify your A/V cable connections: The TV/HDTV switch in the main cable connector should be set to "HDTV". The Red, Green and Blue video connections should be connected to one o the two Component input sets on the TV (make sure the colors are not mixed up, e. g. Blue and Green reversed). Also, make sure you haven't connected the Red audio connection to the Red Component jack and vice versa (you would still get left-side sound from the white connector, but no video). Also verify that the audio cable is connected to the correct component input set (Component 1 audio in or Component 2 audio in)l. Check the connector on the X-Box to make sure it is properly seated. Make sure the yellow cable is not connected to anything - it is used only if no component or HDMI input is available on the TV.
If this doesn't solve the problem, unplug the A/V cable from the XBox and try using an HDMI cable connection instead (some early models of XBox do not have and HDMI connector). If this works, there is a problem with the A/V cable connection. Try switching the connections to the other Component input. If that works, the TV has a problem with the Component input. If that does not work, the XBox cable is bad, or there is a problem with the connector in the XBox.
If the HDMI cable doesn't work either, there may be a problem with

The power supply section of the tv needs a voltage rectifier or diode or similar possibly there is a fuse inside but there must have been a reason for it blowing. Usually aging electrolytic capacitors are the cause

Fault to the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
