Re: Compaq monitor

OK your monitor is failing in the Horizontal circuitry.... OR the PSU is failing to supply the correct Voltages. Either way it is probably going to fail completely soon. With monitors so cheap now, here in NZ they are about NZ$20.00 - $50.00, repair isn't adviseable to do so, it would make more sense to put the Repair monies into a NEW screen... maybe time for an LCD?

W2753v screen flicker - refresh

What causes monitor screen to flicker?
keep electronics away from your computer. Mobie phones etc. can distort the image shown on the screen for periods of time, usually when a text or call is coming through.

A nearby device can cause stray magnetic fields that will cause the display to be affected.
A problem inside the monitor will cause the display to have problems.
If somebody turns on their monitor nearby, the monitor's degaussing when it starts up will cause your monitor to dance wildly for a moment or two.

Answer well one major cause can be the weakness of the electron gun that fire electrons on the silicon plate (pixels) that produces image on the screen so there must be some problem in electron gun in my view

Compaq fs740 text too faint and fuzzy to read well

Firstly you need to switch to the monitor's optimal resolution of 1024x768 @ 85Hz and before anyone posts anything about resolution 1024x768 @ 85Hz is the optimum not the maximum. To change to this resolution: Assuming you are using Windows XP click with the right mouse button an an empty part of the desktop and select Properties (or click Start, then click Control Panel then click Display), on the Settings tab, under Screen resolution, drag the slider bar until it says 1024x768 and then click Apply. Also in Display settings you'll find an advanced button, in the advanced panel you'll see the option to adjust the refresh rate, try adjusting this to 85Hz. Now press the Menu Button on the front of the monitor and press + of - until you see an option called "Degauss" and press the select button on the front of the monitor, your screen will do a disturbing jump and flicker accompanied by a metallic thud, this is normal. If this doesn't help message back.

Flickering and screen dark

sounds like the lamp on one side of the monitor is going out.

It is repairable depending on how tech savy you are.

Samsung 226bw visible flickers just after it is turned on

You may have a faulty inverter or loose power inverter connection. OR
You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Concave screen problem also

OK All these Compaq's have a Power Supply problem, or a Horizontal Voltage problem.. meaning they are on the way out. The SMPSU's in these units often fail along with the Horizontal Drive Circuitry. I think it is time for a new one? Repair of such a unint would barely be "Ecconomical" IMHO.
