Moniter stays blank

Yo my lil bro has a mag crt moniter i have no idea what model it is but one day i was installing a bounch of games and updates on his pc and i was on there for about an hour then i left the room to see what else i could put on there and i came back 5 mins later and the screen was black like it wasnt on but the moniter was on. so i moved the mouse arround to see if it was on stand by, then restarted the pc, then i turned off the monitor and turned it back on and still nothing but the green light. i also tried see if it would work on my pc but the same prob presist. so i turned off the serge protector and waited about 5-10 mins and i switched it back on then turned on my moniter without any pc connected and the same thing happens and i also realize thhat theres no semi loud electro magnetic pulse sound with the click at the end. i just get a quiet sound thats high pitched were that sound is supposed to go off. is there any solution to this??

I used to repair LCD flat screen from Dell. I am not sure that my method might be applicable to your CRT monitor. Anyway this is how to examine what wrong with the monitor. You have to check if you can see the image on the screen or not after it went blank (Power on both CPU and monitor) 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. In my case, I can see window image using flashlight and check lamps inside. Some of them were broken and it is very easy to replace. 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.
Thank you

Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer or service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

Hi,

With or without the drivers, you can still try lowering your display properties (resolution and refresh rates) PC side. Should this not be sufficient, please post back the brand/model of your computer or at least the video card that is being used.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Moniter won't turn on


SOUNDS LIKE POWER SUPPLY IS OUT OR POWER RELAY IS Bad.

Probably cheaper to replace this mointor with a new lcd which uses 50% less current.

even if you find the parts to fix it i suggest replacing this moinitor altogether electrical failure is a sure sign of other problems in the future.
