what a replacement for one that is damaged or failed? That's a highly specific request.

forget it, most modern consumer equipment will be a 'throw away and get a new one', unless the fault is obvious and easy to fix with simple parts, or the model is nearly new and still in production to get such complete system part.

At work we see nearly new laptops returned for faults and simply replaced, similarly monitors are rarely 'fixed'. Only if you find an exact model match with a different fault (smashed screen for example) then you might be able to swap parts to make one working one

Or do you mean the graphics card fitted in a PC to drive a flat screen or CRT monitor? Most PCs have them built in these days.

I actually mean the board inside the the flat srceen monitor, m y daughter plugged a 15volt dc supply into the monitor when it should have been 12volts. She was cleaning at the rear of the desk pc when the cables came out of the monitor and printer and when she replaced them with what she thought was the right cables and when she the monitor did not work!!! I have taken out the board and I can see a chip burnt out on it

Best bet would be to find a faulty (such as smashed screen) identical model on Feebay I reckon. Given you can now get a 19" tft for sub £100, I can't see a major component being cheap enough to make it worth repair (based on spares always cost a hell of a lot more than they should).

It's worse than that it's dead, Jim, dead, Jim, dead. (There's Klingons on the Starboard bow...)

Seriously, I think you're out of luck. Monitors aren't designed to be repairable these days.

Thanks Alex, gone are the days when you could repair things, all those years I spent on course's and repairing things are now wasted

and they try to tell us to recycle

If its obvious what component is dead (ie its black and sooty) just desolder it and solder in a new one.
Maplins and the like will probably sell you one - or you could do what I used to do - pull apart househol objects til you find something similar looking.

My 'just over a year old' laptop has a dodgy screen. replacement costs nearly as much as a new one so I just use a flat screen (bigger and better) for about £100 mounted above and behind.

If a chip is gone they are normally fairly specific. I had a sony 21" CRT monitor that broke. The chip from sony cost £35, and even then it was very small surface mount, so very hard to solder without the correct equipment. it worked for a few months then broke again so i gave up and at the time that was worth about £500.
