You can also try booting with only 1 RAM mod connectet at a time. Make sure to check the working one in both slots incase the mainboard is defective. If the unit boots with one of the RAM mods in both slots the other one will need replacing.

I have just fixed an Aspire 7250 with following symptoms: Only blue Power LED or battery charge LED come on, fan spins, no backlight, no video either on internal screen or VGA output. Problem solved desolderig BIOS flash chip (W25Q16) and flashing BIOS 1.10 with an universal programmer.
Remove the main battery and try again, also! the power adapter charger should be checked for correct voltage, if okay! pull one stick of ram and test, and the second piece not forgetting to put the first one back and power up, if all this fails you will need to get it assessed.
If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp.

Try this to see if can give us some codes with it's on board diagnostics. Hold down the function button of your laptop and then the power button while still holding down the Fn/Function button on the left side of the keyboard. See if this gives you either an error message on your screen or, flashing lights above your keyboard. Pay attention, write down what lights where lit up what ones flashed, etc. This is to diagnose if the LCD isn't working. Comment back if you get either the light code or the error code on the screen. IF nothing happens try holding the Fn/Function button on the left side of keyboard and holding the F4 button, see if that makes any lights flash above your keyboard.
Laptops are so integrated that usually a system failure that involves power issues such as in your case where you cant get it turn on with anything on the screen mean the mainboard (motherboard) is damaged. This usually leads to buying a new laptop or paying for the board to be replaced which usually costs as much as the laptop.
you get a black screen right, nothing at all then no bios, no logo, nothing at all?
Do you get any beep codes and if so in what order?
did you try different ram?
First try to plug your laptop to an external monitor. If it works, you screen is bad, if it doesn't you probably need a new motherboard.
