Sounds like the Flyback or HV block if it was screeching. You can get the Flyback 259296 and the ITC222 HV block at the following link. They provide step by step instructions.

High pitch noise from speakers


Hello there!
Sometimes High pitching its just that, static on the area, like if you are near a microwave, or near other electronic equipments, but, if the skreetching sound keep going or even if you do nothing it could be a line inside the sound card, or you need to clean the volume botton with special electrical cleaner. other that these, its contacts, or bad cap for the volume board inside.
Good Luck!

This tv is under five years old?Yes,it is worth fixing.Over five,i would compare the prices for a new LCD tv and the quote priced from the Tv Tech.for the old tv.This tv have high voltage problems around the Deflection circuitries area.Could be any things burn in this area.The high pitched whine sound,i'm sure it is from the FBT-the high voltages flyback transformer,high voltages current have no where to go.Must hire a tv tech. to troubleshoots and replace parts on the Deflection circuitries area.Also the FBT could be dead too,because HV Current bounces back forth and have no where else to go.The prices to troubleshoot unknown problems is about $400 bucks and plus cost of replacement of parts.

My mouse will stop working and when i turnn off my pc and turn it back on i get high pitched sound and the pc will not come on


sounds to me like *********** board has went bad. You can try removing your sound card (if it is a PCI card) since the high pitch sound is most likely from it. If you only have onboard sound then I am afraid you need to have a technician diagnose the problem.

High pitched noise


It sounds like you may have a bearing problem. The motor bearing eventually gets damaged by the water vapor that is drawn in by the fan. This will cause a high pitch squeel from the motor. It is possible to replace the bearing, but it should be addressed by a professional techician.
