Solution: Replace cap. Radio Shack sells a 1000uF, 35Vcap for $2. This will work.

Why did the cap gobad? The cap is too close to a heatsink and over heated.

What does this capdo? This cap sends a signal to an ICwhich keeps the monitor 'on' after the power switch is pushed. When the cap is weak, AC ripple voltage isapplied to the IC and it sends a signal to shut the monitor off.

Opening the Monitor:These monitors are difficult to open.

The two plastic pieces snap together and must be pried apartwith a flat screw driver.

After removing the stand, you need to insert a flat screwdriver at the bottom of the screen where two slots are located. Then work the screwdriver around until the two plastic pieces are separated.

Remove the cover plate and unscrew the push button circuitboard.

Unplug the monitor cords from the driver board and removethe screen.

Unscrew the mounting screws from the power supply board andremove.

You will need to pinch the plastic support in the middle ofthe board to remove.

Cap Replacement:

Cap is located near a copper heat sink and the value will beon the side of the cap. It will be bulged up on the top. You will see burnmarks on the board surrounding the cap. Unsolder the cap.

Install the new cap and solder. Make sure you connect + ofthe cap to + marked on the board.

Be careful not to solder across joints.

Keep leads long so you can bend the cap as far away from theheat sink as possible.

Reassemble monitor and turn on.

This should solve the problem.

Display fails after a couple of seconds


Connecting a different computer that works to it doesn't fix the problem(what does that mean, its not CLEAR at all)
my guess is you meant the new PC fails on this bad monitor , too.


ok the monitor fails on PC #2, sure....
so the monitor is bad, why ask for help, buy a new monitor.
why spend $100 to fix it when new is %50
why>?

your not going to fix any monitor, here, on fixya,
but there is one thing to check the very old monitors from compaq
ive answered this 4 times here now.
has menu botton
see that? push that now on the monitor
see that menu..
? one menu selection , has silly horrible, power saver timer on it
and a RTC clock that keeps time of day, (pc can be OFF)
if the power saver is on , get it off now, and if paranoid set the clock.
id set it. so its double safe, see?
this happened back in 2002.
i read you users guide for you its a 2001. oops, its got the above BS.

read page 18 and all related pages to this. clock and saver.
page 18 there, page 16 real.
if it one , the INANE thing will go to saver at odd times.
later this was removed for VESA , update, remote sleep rules. and time.

If you know how to open it up and get to the power supply you will find three capacitors 2-820uf and 1-330 @ 25vdc 105o.they will have puffed up tops replace them. FYI the monitor has a 3 year warranty.

LCD Monitor - green power light blinking - nothing on monitor


Carol,
It sounds like your computer is putting the monitor in power save or sleep mode, and the monitor doesn't respond appropriately. The monitor might be faulty, or overheating. Make sure there is adequate ventilation around the monitor, and that it is clean and free from dust around the vents on the case.

Another thing to try is to check your computer's screen saver and power saving settings. Try turning off the "turn off monitor after [interval]" setting and see if the monitor still shuts off after several hours.

Good luck, hope this helps.

My monitor turns itself off


If it's only a few months old then send it back under warranty.
The fault you have is the inverter circuit.

Hope that helps. =)

My 4 month old laptop is not working


If the monitor turns black - maybe you have a screen saver or there is a fault with your display. Try using an alternative monitor or flat panel.
