Hi there, My monitor got blank. There is no display in the monitor, i checked on other computer also. I checked the ciruit and found the irregular voltage at SM transformer. Does the voltage at the pin no. 1 of SM transformer is higher than the voltage given with pin no. 4 of it.
Does the thermistor sounds beep when checked with multimeter, I don't have CRO to check and I am willing to check it myself. As I have learned the maintainance course also.
And tell me some technique to check the voltage after the SM transformer. The EHT also doesn't produce I think the power supply is out.
my monitor initially display the windows logging in, after finishing the logging it goes blank but the cpu is runing. how can i fix it? my monitor initially display the windows logging in, after finishing the logging it goes blank but the cpu is runing. how can i fix it?

c. Install new Display card and check display, if not giving display it means motherboard have a problem
2) LED not giving power on then problem from monitor
a. replace monitor power cable and check display

If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.
Can I assume (?) you re-tried firmly checking each cable connection and the power supply is soundly in place including checking the fuse in the plug That's all I can suggest as the things I would do if in your shoes.
The power -inverter board probably needs an overhaul.
I redo many of these.
If the screen was pinkish or flickering before it finally got to this point, it is possible that a bulb has gone bad.

Sounds like either your video is out on your computer or the monitor is bad. Does the monitor work on other computers? Will another monitor work on your computer? This is the only way to figure out if it is the monitor or the video card.
Hi this is the way how to examine what's wrong with your LCD
monitors. Power on both CPU and monitor. After going blank, you
check that you can see the image on the screen 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.
