LCD Screen backlight problem
I have an Acer AL 1521 LCD screen. I have bought a newer power supply but after a few minutes the screen goes black. I can see that there is writing on the screen but it is too dark. I suspect that my backlight might be packing up. Any suggestions?

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!
