Question about Computers & Internet
Hi I have two HP 2009v monitors that have previously been working fine, all of a sudden, after turning the base unit on windows Xp shows the, monitor lights are on but the screens show blank, do you know of any cause & resolution? Thx
I had this issue with my HP monitor too. Turn on pc and look at the monitors with light shining on them - you'll probably see the images, which indicates they illumination portion of the monitor board burned = much cheaper to replace!! You did not mention if they are L.E.D., but I'm almost willing to bet they are - and over 3 years old too, huh? Sorry for the bad news - hope this helped!!

Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After it went dim and blank, you have to check if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

You have a monitor with a common problem. After a few years some LCD monitorswill blow a power supply. The problem is caused by parts calledcapacitors overheating in the confined space of he monitor. If you aregood at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htmYou can take the back cover off your monitor and look for the bad parts,replace any that look like the pictues and your monitor should workfine. The capacitors do need to be installed with the correct + and -connections, note the stripe on the old one and insert the new one thesame way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.

Testimonial: "I am very happy that this guru was able to concisely evaluate the problem from the information provided. "
The power supply-inverter board is probably at fault. Remove the back cover and locate the standard ac power cord connector. The board that the power input connector is soldered to is your power supply - inverter board. Check the electrolytic capacitors on the board. They probably went bad. A visual inspection is usually enough to find out which ones are bad. They will be either bulging or cracked at the top and leaking fluid. I usually replace all of the capacitors that have the same rating whether they look bad or not. Will save you another repair later. If the caps don't look bad, you can take the board to your local tv repair shop and have the caps checked with a esr tester. It's more accurate and they can be tested with the caps in place. Hope this helps.
