Resolved Question:

I have 2006 Magnavox model number 37MF33ID/37. It wont power up. I press the power button and it flashes a continuous green light on and off. On occasion the screen will also flash dimly on and off in the background. After a while it may or may not eventually power up. What is the problem?

Hello

 

OK what you have here is failing electrolytic capacitors on the powerboard you need to remove the rear of the set trace up the powercord to the powerboard and look for leaking or ballooning electrolytic capacitors

You can get new capacitors at radio shack or similar or online at www.mcmelectronics.com take note of their working voltages and values fr example 1000uf 25volts and they can only go back in one way as they are polarised

 

Let me know if you need more info please
