Its only an idea!
Crt monitors needed to heat up the vacuum tube. Before opening, so i guess you just need to wait for it to heat up. Then try to turn it off. then turn it on again.

Monitor wont turn on help


Hello there, first thing you should do is to check the power cable.You can do that by changing it with PC power supply cable .It is the same. If it turns to be OK then disconnect the VGA cable from monitor and then try to power monitor on.There should be an activity on front power LED. If the power LED is not showing any light at all, then do not go further the unit is not working .Else the power led should blink a couple of times then a window pop up scrolling on the lcd saying :" no video signal" so the unit is OK ..Hope this helps. Cheers.

Whats the problem with no picture on the monitor but the cpu is working


Can you observe any LED lights on the monitor panel when you try to turn it on. If no then check your power cables. If you can see the LED lights but screen does not show try to unplug the VGA/HDMI cable and clean it by blowing air through the plug and then reconnect it. Also try to turn on the monitor without connecting it to the monitor as this will verify if the monitor is OK because if it is it should display a message to check the input signal or no input signal is detected. If it does and you are still not having a display then the problem is probably in your CPU and more specifically in the VGA card.

I have the VE278Q which is connected by display port, every time i turn off my computer and then turn it back on the monitor can't be found, I have to unplug the display port cable, unplug the monitor,...


when you say monitor can't be found did you mean the monitor has no reactions when you turn on your pc?

here are some test you may need to do to know which part is faulty
1. Turn on your computer, did it display the monitor's logo on screen? When it does monitor is good, when only blank screen it could be the vga cable or the video card.
2. See if the led indication lit. When it lit to steady green, it's good signal is coming in from the video card. It should be followed by screen display. If no display it could be the backlight inverter lamp busted or faulty inverter board. When lit green then turns red, no signal coming from the video card. Check vga cable if fix properly to both monitor and video card. Or may need to reseat properly connection of video card from the motherboard. If no led indication lamp, then monitor is dead. Check ac power cord for continuity using multitester. Check power supply section in the monitor, replaced bulged or blown capacitor with exact value, this components were the first to get affected when lcd monitor failed o turn on.
3. When computer was turned on got display and then monitor turns black, go check the vga cable, Fix the connection properly or may need to replace it with new one.
4. When no signal appears or display blank screen after logo, then check video card. First remedy is to disconnect it the reseat properly to the motherboard. If this have no effect change your video card.

go follow these steps and let me know which is closely to your problem so I can give you a good advise.

Power on power led blinking


Hello.

The LED blinking light usually means that the attached PC is not powered on or the VGA connector (end of cable connected from the monitor to the PC) on the monitor, the cable or the VGA port on the PC is faulty.

Try your monitor on another computer. If it works, there is a problem with your PC. If it doesn't work, the VGA connector, the monitor's VGA cable or the monitor itself, is faulty.

Hope this helps.

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!
