Backlight problems


If the capacitors in the power supply are bulging that indicates that they have failed internally and need to be replaced. That would cause the back light inverter to shut down just like you are having.Replace the capacitors and you should be good to go.

Compaq 1720 monitor: the green light on the power supply went away, the voltage converter was very hot and the monitor went blank

You need to find out if the power supply is still putting out 12vdc, you may have to test it with a load (use 12v car bulb such as the brake lamp). It is getting hot can be due to bad power supply or too much load because of short circuits in the monitor. Please post back what you find about the power supply first.

Went in and out til it finally went out

This is very likely a bad power supply inside the monitor. A person with technical skills could replace all the ELECTROLYTIC capacitors in the power supply and likely solve this.
** hazardous voltages inside. Technical person only.

Turned it on a minute later went black

Good day sir/ma'am hi, if you monitor turns black, here are the more common probable reasons;
  1. Your PC went to standby the screen saver kicks in, just reset your PC then the monitor will power on again.
  2. If not, your PC is not giving you video signal, check to see if another monitor will work, we then know what part is bad, the monitor or the PC.
  3. If the monitor is the culprit, then your monitor's back light or inverter board just went bad. you need to replace it.
There are usually two main circuit board on your monitor, the power supply board and the main board, at this point, you need a professional to do the work.
The process is opening the monitor and locate the LCD screen connection to the main board, to check if the contact is snug. we then test. if still nothing happens, Then we go to the power supply board, to check for connection problem, It would help if there are light signs, like blinking, orange, red, green and the likes? Anyway, if the power supply board is not the faulty one, we substitute the main board with a good one and test to see if it will work, test again. If still no respond, we test a new LCD unit, then test, at this point the monitor is working already, if not, we then replace the power supply board. Huh, very expensive, we already have a new monitor. Reminders, these are to be done by a trained personnel. If you attempt to service this, its expensive, so I suggest you let the service shop do this for you to replace only the faulty part.

My Dell 1905FP 19 monitor went black & green power light flickers

It sound like a short circuit. I had this problem with 1907FP model. It had an USB port on the monitor which got damaged and it was shortening to the groung. In your case it might be a bad internal power supply board.

Monitor just went off. no power light. changed fuse but monitor is completely dead

possibly a power surge killed the main board in the LCD. if the fuse was blown i would suspect a power surge. you could replace the circuit board. either that died or the power supply died- depending on if it has internal or external power supply that might be blown as well.

i would take it to a professional LCD/ LAPTOP repair person. they should be-able to test it and let you know what needs to be replaced
