LCD Monitor Troubleshooting

Hello.

I have an S-17 AG Neovo 17" LCD monitor that I found in a dumpster.

It didn't come with a power supply, so I bought a new one for it.

It works great except for one annoying problem; when it initially gets an analog signal it can take over half an hour for the screen to display. It shows a black screen. Once displaying, it works normally for hours at a time. The longest it's been running so far is over 11 hours.

The screen initially lights up fine with the "no signal found" message, so it's not the backlight.

The amount of time the monitor is powered before the initial VGA signal is received (by turning on the connected PC) has no effect on the delay.

Multiple PCs, video cables, and video cards have been tried. The problem is identical with each configuration.

The delay also occurs when the system automatically powers down the screen due to inactivity.

The delay does not occur when the machine is restarted through Windows (warm booted).

With or without drivers installed the problem persists.

The digital and S-video ports have not been tried.

Any help would be appreciated. It's otherwise a perfect monitor. No stuck pixels or cracks.
 
The 3 1/2yr. old 17" lcd will probably be the next one you find in a dumpster for the annoyance of repeatedly turning off and then back over and over again in order to see it finally stay active and displaying the Windows desktop for more then a few seconds! Once that is done daily as of lately you can reboot, boot up in Vista instead of XP or vice versa here and have no problems.

It's just getting the lcd to stay in the active not standby mode for longer then a few seconds. This is no surprise since lcds are generally seen lasting longer then crts having a 30,000 to 50,000 hour life span over the crt's what 10,000 to 15.000. There's always a good reason why it's in a dumpster! Foobarville!!!
 
Whatever takes the cake! :P

I'm about to toss the monitor here soon enough maybe out of a window but still need it until deciding on a replacement. Fortunately I had already planned on getting into a newer HD type display anyways after Q4 2007 was over.

But for fixing something found in a dumpster? The cost of repairing an old lcd someone tossed isn't worth it compared to buying a new or at least somewhat new lcd in good shape.

I've found that this is rarely the case with computers and peripherals. On average, 75% of the equipment is there because it's outdated or has cosmetic damage, not because it doesn't work.

The last LCD monitor I found in the trash, a 15" Dell, worked fine and came with both cables. It simply had a few stuck pixels and some scratches to the edges of the plastic casing.

LCDs are often cheaper to repair than replace if the display is still intact. They're a lot easier and safer to work on than CRTs. They're just unfortunately more prone to damage in the first place.

Has anyone run across a similar problem with an LCD monitor, and did you find a solution? I'd like to keep this one because it's nicer than anything else I own.
 
Even if someone tosses something simply due to a newer type coming out there's still always a reason why someone dumped it. The probelm description just happens to match what is being seen on an older 17" model lcd where the time factor outweighs any reasonable repair charges.

At this point I have the choice of leaving the system running 24/7 or fighting with the on/off switch repeatedly until the desktop remains displayed. After nearly full years of use this one will simply be another one recycled which will be the case here. Any old monitors are generally seeing that over simply tossing them into a trash bin.

The model you have there should be at least brought into a place that services or ships under warranty to the manufacturer since they can make an inquiry on that make and model. After a certain point however even lcds reach the point of no return.
