Sounds like you need to repair the power supply, don't fret, it can be really easy.  Here is a pair of youtube videos I made after following some advice on this website from other posters:

I had the same problem with the blinking green light. These are the parts one the power supply I replace to repair it. note: If the power supply is repaired you will get a solid green light and the backlight will light up almost immediately.

I have a flat screen lcd 42 inch model number 37MF321D/37 and the on button just keeps flashing and the remote does nothing?


You have either a bad power supply ( a very common problem) or the inverter board that runs the back - light is bad. The power supply board will have capacitors that are leaking or puffed up looking. Same on the inverter board. If you can get a component leval repair then that is cheaper ... But most techs just replace the board. Not a do it yourself job. Expect a cost of $200.00 to $300.00

Not powering up right away


This is a big problem with these tv's. Magnavox built them with undersized capacitors, and they blow. You have to open the back, remove the power supply and replace the capacitors numbered 2074 and 2081. This sounds like a real tech job, but read my other solutions, and you will see it is not so hard. Good luck.

This is a bad power supply and an easy fix. Their are several electrolytic capacitors on the power supply. If one is bad it will have a bulge on the top. Mine had a bad 2200uF and a bad 1200uF capacitor. About $7 worth of parts at Radio Shack. Radio Shack had the 2200uF but it was axial leads instead of radial. (leads come out of each end instead of one end) but It will still fit. They only had a 1000uf capacitor so I combined that with a 220uF capacitor and wired them in parallel. Make sure you put them in with the correct polarity.
