Sansui aux-410r amp crackling when switched on followed by high pitched sound and other sound like vinyl played at high volume and stylus being dragged across it .can anyone help please.


This is some kind of componant fault. To find out where determine if the sound is in one channel or both. If in both it could be in the power supply or in something that has both channels common to it. If in just one channel than at least you have the good channel to work with. You can test the bad channel by poking it with an insulated tool. It should make buzzing noises. If it makes buzzing noises in the good channel and is differerent in the bad in anyway you have found something. If the sound also comes and go suspect bad soldering.

High pitched noise coming from TV

High pitched noise red light blinking


A high pitch noise comes normally from blown capacitors from the motherboard or the power supply. But mostly high pitch noise comes from power supplies.

You could have to open up the power supply to see them.

Verify if it is the case and replace the faulty part.

High pitched noise


I am about to post a in depth guide about how to fix this problem. It's because a capacitor inside the TV has blown which causes the buzzing high pitched noise. It's really easy to fix however and only costs about £1 / $2 to sort out.

You can read a similar guide here http://www.fixya.com/support/r741402-polaroid_flm_373b_lcd_tv_black_screen but I will shortly be uploading a guide on the buzzing problem!

High pitched noise


The power supply is starting to fail on your LCD. The noise you hear is because the circuit is trying to provide the proper power to the rest of the circuitry and is forcing itself.
The noise does increase if you tune to an HD channel because of more demand for power for a brighter picture.
Let me know if you need further assistance.

High pitched noise


There is a singing coil in the power supply. This set uses whats called a Switch Mode Power Supply(SMPS) and as the picture changes, so does the amount of current the TV draws. Thats why the sound changes with the picture. This could be an indication that a part is going to fail soon or it is just a loose coil winding or a transformer winding. You should have the set checked out by a pro to be sure. Good Luck
