Why is my Haier washer making a loud high pitched noise?


No. The high pitched noise did not originate in the control panel but rather in a part of the machine that was chafing or rubbing against something. And now the mechanism is stuck. Check for that first before messing with a control panel.

`How do I fix my LG tv? It's making a high pitched noise and there is a black screen, is it fixable?


Get it to a tv dealer but my guess is its died. It may not be economical to repair but you may be pleasantly surprised and its a small job. LG are usually pretty good so I'm surprised its gone at this age.

High Pitched Noise Coming from Sony STR-DH510 LCD Screen - how to fix?


Hello
The problem is with its backlight inverter board. there are some step-up transformeres [small ones] fitted on board. If any one's core bacome loose this fault will occur. Just open the TV and listen to which one makes hi-pitch noise. Replace it, if you can buy it from the electronic market at your town. In most cases, the inverter board needs replacement.
This board can locate on the right or left side of the panel, fitted vertically.

When plugged in via usb, the LIDE 600F scanner makes a high pitched buzzing noise and will not start up.


Hi

The scanner is not able to find the home position to start.

Hence open the scanner and check to make sure the scanner assy. is moving to the end and when it senses the home position it will try to move a little away from it and then return back. But if the sensor is dirty or broken it will make a loud noise like belt slipping.

Try to find the sensor on back of the Tube assy. and try to fix it.

Mother board problem


The noise must be coming from the power supply. The only thing running before you press the power on button is the PSU.
Unplug the power cord on the PSU. Check the back of the PSU for a red slide switch. Make sure it is set for 115v. Than disconnect the main power from the motherboard. Plud in the power cord, (still hear the high pitch noise?). Swap out your power supply.
