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?
