May be a bad monitor, or possibly running the monitor at too high frequency/resolution. Try changing to something generic like 800x600 at 60Hz to test and see if it's still gdoing it. If so prob a bad monitor

View sonic computer screen was dropped and now when you turn it on the picture comes on and then it emits a high pitched sound and turns off. any suggestions?


Sounds like you may have broke at least one of the lamps . The high pitch sound you are hearing is the high voltage that goes to it .

I have a dell 153fp and it is brighter at the bottom of the screen than the top. It also makes a very high pitch noise. Is there any fixes for these issues?


Check the lamp caonnector (white connector with pink and white wires ,or pink and black wires), look for arcing on the board around the inverter transformers. It sounds like the top lamps are not on fully. It can also be from bad soldering works at the lamps ends.

SyncMaster 793DF 17" CRT Monitor: monitor makes high pitch noise...


With a piece of wood or plastic hit the flyback with the monitor turned on. If you note some change in the noise. Replace the flyback.
Normally, it is the cause of the noise.

Warning: High Voltage!! Do at your own risk!!!!!!

Monitor Goes black, or flickers on and off


The high pitch sound is coming from the inverter. It is faulty and needs to be repaired or replaced. The inverter supplies high voltage to the CCFL lamp, this lamp gives the backlight to the LCD so you can see the LCD images.

E153fp high pitched sound when on


Sounds like the LCD or the inverter are failing. Generally cheaper to replace than to fix

Dell E197FP - Screen turns off and on constantly


Check the video connector to make sure it is clean and tight. Look closely for broken or bent pins by GENTLY rubbing your finger across the pins.

Otherwise, it sounds like the monitor screen is failing or has faulty wiring or components inside.

Sounds like you could have an open ground? Also might check the wiring to see if you have a faulty connection in VGA cable or power supply cable

Screaming acer!


sometimes if the inverter board (the part that drives the backlight) has a cold solder joint on it, it can actually generate a high pitched resonating sound (aka a screaming squeal sound)

if it's under warranty, have the manufacturer correct the problem.

if not under warranty, retouch the solder points on the inverter board, or have a repair tech fix it for you.
