Question about Sharp LL T17A3-B 17" LCD Monitor

2 Answers

LCD monitor very dark.

Hi my LCD monitor (Sharp 17" LCD LL-T17A3-B) is very dark I can hardly see the screen, it seems like a light has gone inside. Can anyone help confirm what the problem is and how hard it is to fix? Are the parts avialable? Its a good monitor but seems a shame to throw away. I can see the OS very faintly so its a monitor issue, hopefuly its a easy fix? Thanks Dan

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.

The fault may lie with the ccfl inverter which basically provides a high voltage to drive backlighting for the lcd display. Not sure where you can get this part other than Sharp, but look round on the internet on this subject. I successfully repaired a similar problem with a portable dvd player using a ccfl inverter normally used to modify pc base units with neon-type tubes. Cheaply available at Maplin electronics,but may be a bit large to fit inside the monitor? Could be fitted outside as the wiring is quite long enough?

Open monitor and look at power supply board for capacitors which are "balooning" or deformed in any way. These look like cylindars on the board. These tend to dry out and make what you are describing occur. Replacing them usually fixes about 80% of the problem you are describing. Those parts run about $0.25 to $0.75 each.. well worth trying, right?

LIGHT GONE IN SCREEN
With the unit turned on, turn off the lights and with a flash light shinning at the LCD screen, do you see any images ?

If so, the Back lights or inverter have gone south.

That is a cheap 17" unit and would not be worth the repair cost.

No picture, monitor won't show anything black screen. Monitor was working fine put it on another computer and it won't show images. Could it be part of the power saving system? Is there a reset button?
Does the monitor show absolutely nothing, not even when first turned on? In that case maybe the cable could be defective or connected improperly, or the new computer might not be compatible (or set to output to, say, digital port, while you've got a SVGA monitor). In that case you'll need to connect a working monitor for the time required to reconfigure the computer.

If the image does appears at boot, or resetting the computer, and then disappears, it could be that the new computer is set to a resolution which is too high for the monitor, which goes in protection mode and effectively turns off. Again you'll have to gain access to the computer (maybe booting in Safe Mode) and lower its video resolution to something the monitor can handle.

Hope this helps, have a nice day

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

Are you using the digital connection?? If so try using both the analog and digital connection then set the digital as the Main monitor in your graphics card interface. To check if the backlight is out, darken the room, and light a flash light into the screen. If you can see a picture, then you need to replace the backlight. Good luck
