Question about Sony Computers & Internet

Open Question

My HMD400 Sony monitor suddenly goes blank(black screen no image no raster) after clicking on(green lite) status..then reverts to yellow led blinking by the start/pwr button...blank screen/no image,no raster. Other monitors work fine so its not a CPU or software problem. Im thinking it could be a fly back transformer,however, I might pull the main monitor board to avoid the hassle of testing with equipment i don't have, i also understand this glitch could be a power issue too! I vacumed the entire unit after discharging the CRT and didn't notice any loose componant wiring but resistors,caps etc do flame out from time to time!...Help!!!!

Blank Screen while Green LED is Blinking.


It's because I accidentally plug the cable to the built-in graphics card port. Now I connected it to the right one and my monitor is working great!

when you open your pc now,do you still hear a click sounds like you hear before ,when your computer has no problem yet? now there is no sounds .do the ff..
1.try to press the numlock key and observe it ,if the indicator LED lite on and off,the problem of your computer is your video card,
2.if you can't hear anything, when you open your unit and the indicator of your monitor goes the color orange,pls..check your memory .clean the memory and the memory slots using the contact cleaner .before you replace a new memory.
3. and try to use a another monitor,maybe your monitor has the problem.
