    I have my LCD (sharp) bought in year 2004 not working.

    First of all, the power button was not working. I could turn on and off my pc thrugh the PC on/off. I could not turn on/off my LCD as I used to.

    A few days later, now the entire LCD is off by itself. I have no clue. I need an answer for that.

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.

SOURCE: lcd monitor will not stay on

First thing to try, is to check the cable from Monitor To PC Or Graphics Card.
If you have a loose-broken internal wire, this will be the problem. Dry-Solder Joint et,c.

If the cable, has a socket either end, from monitor to computer.

try to obtain a replacement cable. The second option is to test the output source. i.e Graphics card or output to the monitor.

Hope this helps Mike @ Compurepair.

No power in monitor

First check for a LED indicator? if there is one is it changing when you turn on your monitor? if there is changing light then the problem might be on the power supply or maybe on the LCD lamp. To check the power supply check for a defective fuse a defective fuse has no reading on multimeter and the o.k has 000 reading. the LCD lamp power supply can be converted into different power supply. hope this may help you.

BenQ FP767 17" LCD Monitor Problem - Power LED Blinks

Look for small power transistors 2SC5707 near yellow invertor transformers which go to backlight connectors.
But if problem is blinking power LED powersupply capacitors maybe an issue,check visualy and/or replacement.
Also fuse that maybe blown is not glass fuse near mains socket,It is semiconductor black or yellow colour labeled PFxxx near heatsinks of power supply secondary.

Please rate the solution and provide feedback.

Neovo x17a monitor

Are the settings on the video output correct? Is there a green or orange light illuminated. There is a difference between the Power LED and the Signal LED which is green. If you have no signal the LED will remain orange or yellow but not green. If the LED is green, then a signal is getting from the PC but not necessarily good. Check the signal with another monitor or TV if you can. Check the cable.

No power in dell e173fpf

I would expect the same (new) part failed. Try another dual diode otherwise you may be chasing the problem around the board.. Good Luck, Tim
