This is a problem in almost every tv set made as whats causeing this noise is a loosly wound coil or transformer thats vibrating so fast cause theres a tiny gap in between the windings that it makes a noise or "sings". Sorry to tell you to fix this problem could be a hit and miss thing as it could be in the deflection yolk on the neck of the picture tube ,the flyback transformer, the horizontal driver or power transformer or one of the many many coils on the circuit board. If you have no training on tvs then this is not a repair you should try. But to find out where the singing coil or transformer is could be very time consuming and if you do find it theres only a few small things you can do to try and stop the singing. Like sqeezing around the top and the bottom of a coil some silicon and letting it dry before you turn on the set or for a transformer you can take small homemade shims and stick them around the core or underneath but dont break the core!!! other then this simply replacing the part works most of the time too. Good Luck

Squeeky fan belt noise after driving a little

It sounds as if the belt is dry. Belts dry out after a certain amount of time and then start to make chirping noises. If the belt is not badly cracked, you can try using a belt lubricant spray. These sprays usually only last for a short period of time, though.

TV makes a spinning noise coming from the lower right side.

If there is a red light blinking that means that the projection light needs to be replaced.

TV screen Flashes blue and then shuts off.

When it flashes blue, are the flashes bright blue lines going across the screen with the picture in the background, if so, It sounds like the Blue tube or blue driver circuit is breaking down after a short period of time. If this is the case, the uPC that controls the set is detecting a large current drain on and is shutting the set off for protection, An engineers expert eye is required I`m afraid. Ian.
