If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

I recently bought a Hp Lcd w1907 Monitor off craigslist, the screen worked fine for about an hour then went black, button stays blue. Now every time I power on the monitor it stays lit for 3 seconds...


hi the cause is screen back light not working properly. you need to remove the back cover of the monitor to access the internal part of the monitor. then look for the connector of the cold cathode fluorescent tube back light going to the power inverter board of the back light you will noticed a dry joints which cause a loose connection that is why you hear a sound that cause of spark. you need to re soldered the connector or replaced if totally burned.

Try this, no guarantees but it may need to be reset. Make sure PC is turned off. Disconnect the monitor from the PC and unplug it from the wall. Hold in the Power button for at least sixty seconds, then replug it in PC and wall. If it is reset it should start normally. If not it needs further diagnosis.

Monitor no longer works - all black


there is no reset button on lcd monitors, check power cable first, if the blue pilot led lights but no picture, you might need to bring the unit to the shop for servicing..

Printer trouble


Power cycle the printer. If problem remains, try a partial reset. You can do the partial reset as follows:
1. Unplug and replug the unit.
2. when lights flash on power up, hold down the ON/RESUME and PAGE SIZE buttons together.
3. When only the ON/RESUME button light flashes, you can release the buttons.
4. When the lights stop flashing, the reset is all done!

If problem remains, you are fully justified to ask HP to replace the unit for you (well, if you're still in warranty!). Good luck :)
