My TV, HITRON CS 6404SV gives a mild whistling noise when switched on.

The mild whistling noise is usually caused by a fault in the HV circuit of the tv. My money would be on the flyback transformer. Since this is un-doubtedly the most dangerous repair that can be performed on a CRT tv, I strongly suggest that you seek the assistance of a qualified tv tech. I am talking about a part that generates 25000V.

Power light not on, no sceen on , whistling sound coming from tv

The whistling is caused by the power source that is overstressed by a short - a big part inside it has failed. The tv must be opened and the parts tested by a pro. Call one, there's nothing else you can do.

High pitched whistling

Try changing refresh frequency, color depth or resolution (wait for the whistle to appear before testing). Admittedly, you might have to give up some image quality - less colors, or less resolution. There is probably a problem in the TV syncing mechanism - if you can, try getting it replaced. "High pitched whistles" in video and TV hardware are usually harbingers of bad news.
