Does this mean that my Monitor is F.U.B.A.R./Dead? If Not how Do I fix it. Monitor gets power and the green light comes on, but the stay black. Please help.

After I jumpered the picofuse, I noticed that the 2N7000 was running hot. I replaced it with a bs170, (exact replacement). Now the thing works like it's supposed to. After I replace the picofuse, I'll put it back together.

Mine had a similar problem. Try shining a light on the display and seeif you can see (very very faintly) the BENQ logo when you turn it on.If you can, what you will probably need is this:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220271974700

The description says that it is for Dell and HP monitors but I thinkthey use very similar components. In my case I only had to replace theBel 3a ms125v fuse and it's working perfectly now.

Sorry if you don't like eBay, but that was the only place that I could find those parts and the seller seems really helpful.

Backlight is torched, it happens without warning. These can be repaired, but finding the appropriate backlights, and trying to get this thing apart is a royal pain in the you know what! But your backlight has burned out! Sorry!

FIX THE COLOR, IT HAS A GREEN TINT THAT DOESN'T GO AWAY WHEN TRYING TO ADJUST COLORS FOR DISPLAY DON'T KNOW WHAT CAUSED IT
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Different lines of color appearing at the top of screen
Connect an external monitor to your laptop. If the problem appears only on the display of the laptop and not on the external monitor (in the same time) that means the video card is ok and the problem could be: the screen of the laptop or the invertor or the cable that attaches the screen to the motherboard. If the problem appears on both screens, external and laptop, most probably the video card/motherboard is defective.
Have it checked/repaired by a professional.

Westinghouse LCM-22W2 has "ghosting"
Usually, LCD monitor ghosting appears when the cable isn't tight, the cable is faulty, or low quality. The cable should be less than 8-10 feet long. Try using a different monitor cable (they're mostly interchangable) and see if the problem goes away. I'd put my money on the cable or a loose cable connection.

I receive the same error. If I use the profile colors are off (not just a little). Other fora have posted to uninstall the driver and use a generic monitor. This allows Photoshop do its thing properly.

Dell P1110
Hi, The part where you see some color bars and blinking green led is what we call MONITOR SELF TEST. A diagnostic pattern consisting of four colors (red, green, blue and white) appears, and the LED flashes slowly. this happens when signal cable from the monitor is disconnected from the tower and leaving the power chord for the monitor plugged in. If the monitor works properly on a different computer. then its a problem with the computer's video card sending out signal. im 85% sure that its a problem with your video card.

I have a Benq Q9C4 monitor and when I press the power button on the front, it lights for a second and then goes out. Nothing shows on the screen, (It remains black), and no heat comes from the vents, so obviously nothing is working internally that creates heat. Do you have any ideas?
