Question about Computers & Internet

Open Question

I have a cornea MP740 monitor as a second monitor screen. It is not my main screen. It went dark suddenly. I assume it may need a new bulb. I cannot seem to get it disconnected however and some of the things I am trying to pull up on my computer are going to the second dark screen - until I get this one fixed, how do I get everything - like my emails! - to pull up on the main computer screen? And how would I know what is wrong with the cornea?

SOURCE: Monitor suddenly goes black

Is this monitor and LCD flat Panel? If so this is due to a bad power supply, an inverter board going bad or LCD backlight bulb blown. When the backlight goes bad it gets just enough power to start up, but when it is on for a long period of time it goes black because the bulb is not stable enough to hold the charge because it is going bad. These bulbs can be changed, but they also can be costly!

SOURCE: computer monitor wont stay on

LMAO it sounds like it is going into power-saving mode because there is (or it -thinks- there is) no signal. Has it always done this? Try punching up the controls when you turn it on and changing its behavior through those menus. Doublecheck the monitor's connection to the computer. Alternately, if it is connected and a display is coming up for those 10 seconds; perhaps just going into sleep mode, with the power LED changing appropriately; you can look up the exact model, and find schematics and previously solved instances of your case.
Even if you can't find those, you could read through some introductory electronic circuit books (and the internals of the monitor...unplug and read the books' safety bits first) and determine what went bad and how to replace that component.

SOURCE: Why did my HP Pavilion ze2000 screen go black?

john79:

I know that you had a chat about this matter, and I hope that your issue was solved. However, I had made a note of it when I saw the chat go through. I was unable to help at that time, but remembered having seen something of this nature and wanted to follow through on it.

Although the ze2000 is not listed, other 2000 models are listed in the following link as defective - and recognized as such by HP - with this very specific defect. (Please see http://h10025.www1.hp.com/ewfrf/wc/fastFaqLiteDocument?lc=en&dlc=en&cc=us&product=18703&docname=c01087194.)

Again, if your issue has already been solved, congratulations. Otherwise, I hope that the information provided here will be of use to you, either in fixing the equipment problem yourself (perhaps with a BIOS update) or by convincing HP to do something about it. At least you would be armed with good solid documentation of their recognized issue!

If this information assists you in resolving the problem, please take a moment to rate the solution at a "FixYa" level. If you do not feel that you can rate at a "FixYa", please post back with more information regarding what has occurred subsequently and/or more details regarding the situation, and I will gladly help you until we have reached a definitive solution. Thank you for using and rating FixYa!

SOURCE: My new monitor turns on then goes blank after a few seconds.

It sounds like a power issue OR weak signal. If you use an extension cable on your monitor cable this can couse the problem.

Why does my TCL tv stay dimmed and very dark screen? I've reset it and everything?


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I have an NEC '19 Multisync LCD 1920nx monitor. The display went blank and will not come back on. There's power going to it. It just doesn't display and image. How do i fix this?....thanks


the inverter or the lcd bulb may be out. inverters are cheap, bulbs are not. is the screen dark like its off or glowing black? if its dark like the bulb is off, next, look closely and see if you can make out a faint image on the dark screen, if so, it is likely the inverter.

Cornea 1810 monitor power cord


Apparently the monitor's power consumption is near or slightly exceeds the specified value.
My suggestion would be to purchase an adapter with higher rated output current - if for example your original adapter was rated 12V 4.5A, go for a 12V 6A rated adapter. A 30% safety overhead will hopefully contribute to higher reliability.

Used as second monitor suddenly stared to go dark


If the screen is lighting up for a fraction of a second when you turn on & then goes dark, this indicates a fault either with the backlights on the screen or the inverter part of the monitor. You can check the backlights if you have access to a backlight tester, you need to remove the rear cover & connect the backlight cables into the tester, if this checks ok then look for a problem on the inverter board, checking the capacitors for any signs of distress.

Screen went black


I don't know. I've never actually replaced parts in a monitor. If the bulb is expensive, it might be best to buy a new monitor. They're cheap nowadays. Or you can check if there's warranty on the monitor and it can probably be fixed for free.

If possible, try a new video cable. If it does not correct itself with a new cable, the problem is not serviceable. Flat screens do one of three things: inverter will go out (no light), line input board signal failure and power supply low volts on 12v B+.
