    My exact Tv is doing the same thing. It gave us trouble for a while ... then after about 2 years would just show the green light and then never go on..

    I was told it is an ssb board.........$350 dollars to fix...........

    I think this part was defectively designed...........

I have the same problem.

another fixit post tells you to remove the back and take off a metal part:

This is the older brother: A lot of the reviews describe your very problem.

Magnavox should do something about this!

Manavox tv won't turn on after power outage

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

My 2 year old Magnavox 37MF231D/37 LCD TV just blew the picture screen. The audio comes through fine, but the screen is dead black with no menus, info, nothing. I tried various inputs, same result. I...

The problem can be in the backlight inverter board (hard to get to), or the main power supply module may not be working. Look at the power supply first since it is easy to get to, look for burnt parts, bad capacitors.

Either your inverter board or video board is bad. If you can see picture while the TV is on then its your inverter board. If not, video board.

Magnavox Philips 26MF231D 26 in. LCD Television wont turn on. The green power light is on but unit does not work; it won't power on or off using the power button, and screen remains black.

Most likely you have defective capacitors in the Power Supply. It is not an expensive repair but something that needs to be done by a svc. co., if your not familiar with Switch Mode Power Supplies (SMPS). I hope this helps and Thank You for using FixYa.. Let me know....

An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.

I have the 26MF231D and it worked great afterward (even though you can't mount it)

Here is how you remove the cover.

Tv damage

It sounds like u have a damaged lcd panel. When your panel gets like this there is not much u can do to fix it. It will be cheaper to get another TV than to order a replacement panel. If your bought the service protection plan you can get it replace no problem but if you didn't. There is not much you can do for it.
