Computer Monitor Fail!

[Tengtooltom]

My Computer screen has gone black.
When I switched on last night the screen would not come on. The light behind the on/off button on the screen does not come on.
I have checked the mains power lead with my meter - its ok.
The screen is a Dell flat 18.5"
Is there anything else that I can check or just go out and spend?

I'd have a quick look inside first, fuses, loose wires, signs of burning &c.

power off, reboot & see if you get a splash screen.... manufaturers logo or "no connection"... if you do it may be the video card

Some dell monitors have an issue where the power button on the front fails, however you should still get a light on it behind the on off button, which suggests more like a terminal failure.

Computer or TV repair shop might be able to fix it before you splash out on a new one?

I have just connected it to the laptop - The laptop screen adjusts size as if in two screen/monitor mode. Nothing on plugged in screen.
Tried the power off etc but no life on any of the buttons etc.

I am now going to dismantle and have a look......
Can I replace the switches?

I can feel the tension in the room

I've had flat screen TV's and monitor light fail. It's normally a cold cathode item that surrounds the screen. On cheap (Chinese made) it's virtually impossible to seperate so the whole unit has to be scrapped. On quality items it's sometimes replacable.
This gives you an idea -

Has yours got a seperate 12v dc power supply these are favorite to go down,have a feel if it is warm and check there is power getting to the actual monitor.

Most dell monitors glow orange in the off position

Mine doesn't

 

[Tengtooltom]

Mine has the telltale brown goo coming from the capacitors and both are after swelling - just as per the link.

The on/off button used to glow red/orange while off and green while on but it went off altogether yesterday....

Have ordered the parts and I hope to be back in action by wednesday

 

[Tengtooltom]

I got my delivery from www.cpc.co.uk yesterday and spent a 1/2 hour getting up and running again.
Two capacitors (24p each) and a few minutes with the solder gun.

you managed to get all the magic smoke back in then?
