Re: crt not working

Mr fool, Hope I?m not too late but if it?s only five months old you should contact the manufacturer?s technical support immediately. Most computer equipment has a one year warranty and a failed power socket or connection would definitely be covered. If you open the LCD case and try to repair it you will void the warranty. Let us know if you have any more questions and please don?t forget to rate the posting.

Re: crt not working

Well it seems that there is a loose connection inside (cold solder) especially the power supply circuits. try to open it and inspect if there is a bad solder and resolder it. good luck!

No picture on monitor - green power light blinking

There's an internal electronic part/s of your monitor that is cold soldered / defective. I suggest to bring the unit to an authorized service center to properly diagnose & fix the problem. regards

Power light is green but screen is black

Do you get anything at all on the screen--like white writing at startup?
Even if your video drivers have become corrupt, they are not used until Windows actually starts.
It very well could be the flourescent backlight has gone bad. Can you adjust the brightness/contrast at all to see anything?
If those controls do nothing for you, then you're looking to get a new monitor.
Your monitor does have a sort of power supply for the backlight and that could be bad, but if you're not into taking it apart, then you are far better off buying a new monitor.

Blank screen

This looks like a problem with the video card or the power supply to the monitor. Try connecting a different monitor and if you still face the same problem then probably you may need to have a look at your video card or its connection in motherboard

LCD monitor goes blank

It appears that the display resolution set in your display properties is out of the range that the LCD can display.

Try this.

Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)

Monitor is blank but green light is on

if you disconnect the data cable while the monitor is on, you should get a red and cyan message telling you to check the cable, that assures you that the problem does not coming from the monitor, instead check th video card.

Blank monitior

There is probably some electronic malfunctions inside your monitor. Since I will not be able to actually check your monitor, the best solution for this is bring your monitor to a qualified TV/CRT technician in your area for proper diagnosis. He's the right expert and the second opinion to that kind of problem. Problems regarding inside the monitor are usually not fix-it-yourself kind of thing for non-expert like you compared to software problem, which can be mostly fix by yourself guided by an expert.
