Loud sound would be coming from defective color wheel that is mounted i light engine, next to lamp housing. Replacement of color wheel is required expertise/ experience and professional will do that for you in correct and in safe manner.
Contact local tv repair shop to get color wheel replaced in tv.
Thanks.

when i turn on my tv the light turns orange green for a few seconds.

Need to check the cooling fan.
-- open the back cover & unplugg two of cooling fan socket(black & red wires or yellow & red wires)

If the noise still remaining, need to exchange the color wheel.

Hi and welcome to FixYa,

Initially, if you have confirmed that the source of the buzzing sound is from inside the TV, then that would indicate a component about to fail or would need attention. Let us try process of elimination:

• tuner - most unlikely, the tuner is responsible for selecting the channel. No component/part of the tuner could make such a mechanical buzzing sound;
• speaker(s) - most unlikely, the speaker could have a buzz but generally would not affect the video nor cause snow (weak TV signals);
• transformer - a strong possibility although without knowing the exact model, at most generic ideas; power transformer, flyback transformer, horizontal drive transformer (unlikely);
• arcing - another strong possibility. This could be caused by damp, dusty surroundings of the components especially at the FBT area. Another area that could have adverse effect when dusty/damp would be the anode cap.

This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Tt might be the problem with he color circuit board, bring it to the repair shop for repair, or if you can do it do re-soldering to any visual crack at the soldered lead terminal of the components on the circuit board and then try put on to check if the problem goes away?

Is the buzzing coming from the back of the TV, staying loud even when the volume is turned all the way down, or is it coming from the speakers?
