I think its the flyback and its starting to leak. this is a component responsible for the high voltage of your tv set. always observe safety in dealing with this. Have it check by a qualified technician. Good luck!

Hello there, You have to specify where the noise is coming from. Is it coming from the speaker or from the back of the unit. SMPS power supply powering your unit create this kind of noise when some capacitor gone out of their value.

Good Luck.

Check your battery first. Cold weather does horrible things to car batteries... if it's more of a grinding sound I would say that your starter gear is bad. I believe they call it a ring gear? I had a similar problem with a kushman scooter that I use to deliver snowcones through the neighborhoods. It has teeth that need to engage and if those teeth have been grinded down it will have a hard time engaging....
