I would check the DC filter caps in the power supply and voltages first.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Power light is blinking


Count the blinks and the pattern of the blinks (3 long blinks, 1 long blink followed by 2 short blinks, etc.).

Remove the Power Cord, Remove the screw and cover that houses the memory and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.Does anything post to the screen at all when you press the Power Button? Maybe your video card is bad.

Why my acer projector wont flash and shows just blue blink on its power botton


I'm not understanding what it is you are trying to say,it sounds like you are trying to describe two problems.

Projector won't flash? Are you saying nothing displays on the Screen?

And what just shows blue blink on it's power button the computer?

Blinks and Beeps tell the technician what is wrong with your system. Notice how many times it blinks and where the blinks are long or short. There is a pattern to to blinks for example (3 short blinks or 1 long blink followed by 2 short blinks).

I'm going to assume your system has a memory chip problem and when you press the power button it just blinks and nothing ever happens, not posting on the lcd screen at all.

Remove the Power Cord, Remove the Battery, Turn the laptop over and Remove the screw that secures the Memory Cover and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

D100l has blinking caps lock


Give us more details if you want help. Blinking Caps when? When you boot up? Is it booting all the way so you can use the computer?

Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.
Does anything ever post on the lcd screen?

Xerox 4595 canot boot . power save button blinks


Count the blinks and the pattern of the blinks. Blinks and Beeps tells the technician what is going on with the laptop.

Maybe you have a Static Charge Buildup. Remove thePower Cord, Remove the Battery, then Press and Hold thepower button for 30 seconds. After 30 seconds plug the power cord back in(leave the battery out) and hit the power button to see if it boots. Ifit does, you can put the battery back in and let it charge.Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

Dell inspiron 531 with vista home premium, sata DVD/hdd, wont boot past bios screen, blinking cursor in top left corner. with nothing hooked up, says no boot devices available. i have tried each one solo,...


That blinking cursor is the way in which the BIOS is telling you that Windows or any other OS is missing . Since you are getting it without even an hdd connected it means that the southbridge is defective. Which means that the motherboard is dead, replace it.
