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 just fixed this exact problem and it was on the main board. I made a video on what part and how to replace it. I also added a link to the part I ordered to fix it. L5973D STMicroelectronics Mouser

I have a Magnavox 37MF321d/37 and the screen needs to be change. Im a handy person and the question is should i replace it my selft? or should i pay to get it replace? how much will be the diffrent money...


The screen is the most expensive part of the TV alone.
The cheapest new replacement screen will be about $300 at Shopjimmy.com, but they are currently out of stock right now.
Paying someone to replace it will cost more that the TV is worth.You maybe talking about well over $800 for someone to find a screen and do the work.

I hope I answered your question on this one.

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.
