Question about Sharp LL T15A4-H (Black) 15" LCD Monitor

Open Question

SHARP monitor (-B, not -H) has 3 inch wide vertical 'zones' visible in LCD. Worse to the right.

There are 3-inch wide vertical 'zones' appearing on my screen, zones where the resolution appears poorer in each zone towards the right side of the screen and at it's best (ie. normal) in the left zone. There are distinct edges to these zones, but no dead pixels. They are most noticable when the screen is dark or blank (but switched on). The WIN XP 'starfield' screensaver is a good illustration. It shows clearly the defined zones getting more grey/white towards the right, while the left zone appears clear and normal. They sometimes flicker into view even on the brightest screens, and sometimes are only just visible on a fairly dark screen. The only thing the computer does which seems able to affect this phenomenon is if I try dragging a bright window (eg. My Computer) across a darker background, it appears to break the effect up into smaller chunks to the right of said window for a few seconds. I have tried adjusting every graphics card and monitor related setting on both the PC and monitor to no avail, I have tried it on many different computers and it stays problematic as described above. I have tried it with Linux, WIN 2000 and WIN XP (investigated most thoroughly with XP, with which I intend to use it) on several graphics setups. ALL THE SAME. HELP! I do not want to buy a new monitor (note the expense required) P.S. I may even try soldering if that is what it takes (I have basic skills in the area) (:-|)

SOURCE: LCD monitor very dark.

The most likely cause for this problem is the backlight in the LCD. Over time, this light gets dim causing the problem you describe. I have never actually replaced a backlight myself. With the price of monitors these days, even if I could find one I don't think it would be worth my time and money to replace. But if you want to take the chance, try finding a monitor with a cracked LCD on ebay or look at the back of your LCD screen after you remove it from the monitor and see if someone is selling a used one somewhere by searching for the model number of the LCD screen.

I'm confused as to how you're connecting this with s-video. Are you using an RGB / s-video adapter?

What is the exact monitor brand / model?

SOURCE: Monitor menu screen appears on screen

Try a hard reset: Unplug from power source, disconnect from PC and wait for 10 minutes. Reconnect everything and see if the issue is resolved.
If not, then you either have a loose contact on the menu button or failing circuitry. I'd recommend calling Sharp tech support in this case..

SOURCE: Sharp light turns green thern turns yellow screen goes black

it is going into sleep mode, good luck with this.... i am currently asking how to get my hard drive to quite putting my monitor into sleep mode.

although it hasn't worked for me because my screen stays black, one of the options given to me is to try to start in safe mode and then adjust your settings to "never" on the energy/sleep/hibernate mode

some one else suggested that i remove and reseat the video card

hopefully one of those will work for you

Monitor sizes are measured on the diagonal from corner to corner.

A 17" LCD may have a screen width of 12 inches measured from side to side.

If you are measuring a old style CRT monitor (Cathode Ray tube) the visible screen area will be about an inch less as there is about 1/2 inch of plastic frame holding the CRT in the chassis. The manufacturer can advertise the actual size of the screen regardless of how much is actually visible to display information.

If you are talking about software not utilizing all the available screen area to display the image, that is an issue with the people writing the software code not keeping up with the changes in hardware.

In the past year or two, most displays have switched to the 16:9 and 16:10 wide aspect ratios while most web content is still written for the 4:3 old style aspect ratio. Eventually, software developers will catch up with cusrrent hardware.

There is a 4 inch wide back vertical strup down the diplay screen

It is probably be a faulty LCD crystal, or a bad internal connection where the electronics meet the LCD. I would think it could happen if the monitor is jarred or dropped, I guess it could occur also if the monitor was brought in from the cold weather and condensation occurred inside?

Unless you have access to a trained LCD technician, your only option is return the monitor for exchange or repair, or buy a new one.
