is anyone aware of any reason an lcd from a Sony PCG-F630 would not work with a Sony PCG-F540. I installed the screen and when I boot up it shows the background color but no desktop, I have tried switching the video card on the monitor but still no luck, the laptop works great with an external monitor.

Thanks

Every reason in the world... the specs are different. That is like putting a chevy engine in a ford.
Laptops are built for the seller by a number of manufacturers... sony doesn't make its own.
The LCD inverter behind the screen on those two models are significantly different... in size and shape.
There is no reason I can think of, knowing both models, why you would think they would fit each other, because the other specifications for processor, motherboard, etc. are not the same.
It is extremly rare that yu can do this with any product from any manaufacturer.

Is your screen broken, cracked, or damaged? Or did it just stop working?
Most Sony VAIO laptops have an extremely high failure rate of the LCD where the inverter has failed. That failed inverter can be replaced for about $75 by a good repair shop or $155 by Sony. If you replace the screen, be sure to also replace the inverter.
As with the other stuff, the inverters are usually NOT interchangeable.
