This is a system fault but unfortunately,you may have to replace either the power or motherboard depending on whether the green LED blinks continuously or completely dead
Check if the signal cable for the display is connected and whether there is any kink that may break a wire inside the cable. If the circuit for display inside the computer is broken, most of the time you would hear beeping when turning on the computer.
If it EVER works, then the problem is not a failed part, but a weak part. The most likely component type to give you such problems are capacitors. But very few repair techs know how to find such problems, and even fewer have the equipment needed to find the bad one(s) in-circuit. The failure mode is high ESR (ESR means Equivalent Series Resistance). The lower the ESR, the better. Capacitors with high ESR cannot stabilize circuits which demand high pulse currents, such as in switch mode power supplies.
the green light blinking is normal if set has been unplugged--when set is plugged back it should blink for about 70 seconds and then go out--then you can try to turn it on---it is the DM unit inside the set booting up.
If the light just blinks and never stops you have likely bad caps in the DM unit---there are kits available for that.
The other possible reason is that so called reset switch may be bad--fairly easy way to find that out and it is more common than you would think, let me know if you have questions.
Hit the front of the tv near the blinking light... give it a good rap or two. See if this helps. Helped mine. I had the same problem and the tech who came out to the house told me that it would work and it did! I could hardly believe it but it worked.
