Power light is flashing blue but no pic


Please verify that it does the same with other PC also before taking it apart, if it still does not work, then please read below:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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 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.

Samsung t240 monitor lost pic


This problem with the T240 (t240M or T240 HD depending on the coutry) monitor on Windows 7 and maybe on Vista
is due to Samsung´s driver witch is not updated to Win 7. You will have to lower your video
resolution to 1600X1024 (higher resolution accepted) be able to use your monitor. Unfortunately it will not work on Full HD mode on Win 7,
until Samsung releases an updated driver for win7.
I had the exact same problem here and found this information together with the samsung people.
As yet they have no idea when the needed update will be available. Hope soon, till then no Full HD resolution for us.
Cheers from Brazil

NEC 2080 UX - power light flickers - pics of appears broken caps?


you can change these, you need some soldering skills. the monitor is 3 colour sets. so they have same components on the 3 colours. so you take all is leaking out clean the liquid (sulfuric Acid), and replace with a new ones. you find the components in your local electronics stores.

No pic. But it powers up


In this case the monitor itself is damage. If the monitor "SELF TEST" screen appears it is working okay.

Then try checking the VIDEO CONNECTOR and the VIDEO CARD. If both are okay, then monitor itself is bad. Thank you.

Dell flat pannel monitor fail to power up after power outage


rtutt, First, before you start to tear apart the monitor any further, take pic's (close-ups) of screws, cables and their positions BEFORE detaching them from their board mounted jacks. Second, the fuse will be a small pigtail type soldered to the power supply board. It's the board that will have the connector on it that the line cord plugs into from outside the plastic cover. This is Pretty neat for you because if you forget where something goes, you can always open up another monitor. Well if you get the steel shield cover removed (BE VERY CAREFUL NOT TO RIP OFF ANY CABLES OR MULTI CONDUCTOR RIBBON FLEX CABLES) the cables can then be popped off. you can probably catch a video of monitor tear-down on YOUTUBE.com by doin a search on LCD repair. Yes I have seen some that are 8 to 12min long on the tube. Also you will be visually checking all large electrolytic capacitors for SWOLLEN tops of their aluminum can. You will need a large magnifying glass to inspect the solder side of the board for circular hairline fractures around the leads of heavy and larger "through-hole components, that have been thermally/mechanically STRESSED over the years. they will need to be resoldered. Well any way, keep me posted of your progress. Im louie12fix or lmistyrel@ aol.com PS: I have dell and will take pic's of board!!

Try hooking up a different monitor. If that is not an option try looking for a key in the F-keys row that has a pic. of two monitors that might even say lcd on one of them. Hold down the Fn key and push the key with the pic once. If not then push the key twice before letting off the Fn key. And so on

No pic on the monitor


Canon has an option to keep the pic from showing up on the monitor-go to 'clear settings' and put everything back to default.
