The most annoying Monitor in the world

For some reason my monitor is giving out the most annoying high pitched sound in the world. Its a really squeaky sound and Im positive the sound is coming from right behind the glass screen. As soon as I touch the monitor so it moves in the slighest the sound goes away, as well as if I change the position of the monitor, but then the sound returns again after a few minutes.

Anyone have an suggestions of what the hell it could be.

It sounds like sumthing hasnt been oiled enough. rofl.

And its also doing my head in!

Wonder why it stops though if I push my hand on the monitor slightly.

 

Sounds like the high-voltage coil or the high-voltage capacitor is going bad. I'm not a TV repairman so don't ask me how to fix it. AND DON'T TRY TO FIX IT YOURSELF, EITHER; IT STORES THOUSANDS OF VOLTS FOR DAYS AT A TIME--OR EVEN WEEKS--EVEN WHEN IT ISN'T EVEN PLUGGED IN. IT CAN KILL.

It's like this: When your body comes into contact with voltage that high and in free-flow from something like the capacitor in your monitor, it brings the fluids in your body to a boil so fast, it can actually burst your skin open like a breaking rubber party balloon. It is the same process that bursts a tree open and splits it when lightning strikes. The fluids it that tree come to a boil so fast the tree explodes.

I hope I've put the fear of God in you about it. Leave that job to a professional.

 

Put the fear of god in me just abit. I backed away while reading your post. rofl.

The comps been on for 1 hour 10 mins and no squeaking so far.

 

I have close to 40 years extensive experience working on & replacing CRT's for Radar Displays, & TV's, so I can vouch for the previous entry.
STAY AWAY FROM THE INNARDS!!
What you may be experiencing is the High Voltage Lead connected to the CRT from the H.V. Power Supply may somehow have Moisture around it and the High voltage (12-18 Thousand Volts) is just "looking" for someplace to Discharge itself. Or there may be a crack somewhere around the CRT. Even though the face of the Picture tube is 1-2" thick, You could still "Feel" some of the Discharge.
Suggestion I have is take it to a local shop, & have them check it out.

 

reality of availability of tv repairman

How many tv repair shops have you seen in your area ?
Almost nobody fixes tvs anymore. Most of the fellows in that
business have closed shop
Have fun finding a real tv repair shop.
There was a tv repairman in my coffee clutch. Alex was referred
to as a nice fellow "but he really didn't comprehend the meaning of the word TOMORROW "

 

I ran a T.V. repair shop for a short while (8 years) and have repaired many sets that came in with the complaint, "It's making a high pitched squeaking noise that comes and goes." It's was invariably something mechanically loose around the horizontal output (flyback) transformer. Although this component operates at a very high voltage, it's relatively safe to work on when de-energized. It's good practice to use a grounded probe and neutralize any residual charge that the CRT may have since it acts as a large capacitor in essence. That residual isn't enough to electrocute or even injure a normally healthy person, but ever time I ever got bit by it, my natural reflexes caused me to jerk away so fast I usually left some skin behind on a sharp edge somewhere.

Anyway, the solution was often to apply Glytol (High Voltage Insulation goop) to the area around the flyback, after determining as close as possible where the noise was coming from. Normally that was determined by probing around with a dry wooden 1/4" X 12" dowel. The slighest pressure in the right area usually silences the noise and pinpoints the source. Sometime it was only necessary to tighten a loose ***** or tweak the sheet metal housing that guarded the items.

I don't mean to minimize the dangers of working on things such as this but seriously I have never known of anyone to die of electrocution from the residual charge on a CRT of any size. The guiding criteria would perhaps be, if you don't know what a flyback transformer is or where the high voltage wire connects to a CRT, leave the work for someone who does.

Just look at this example of what electrical energy can do and make your own decision.

Cheers. ps. You're correct, there wasn't enough money in that business for me either and it apparently has gotten worse.
