Same issue here and that power supply on ebay doesn't look like it would fit. Would you by chance have a link or pic or this psu? Yes I do understand this topic is over a year old.

I had the same problem with a Magnavox LCD TV. It would not turn on and the light on the external PSU flashed. I found a replacement 12V 5A power supply on EBAY. It brought the set back to life.

Why toymax magnavox 37mf331d 37 in tv worked good i turned it off came back to turn it on and it wont come on the green light that is usually there its not on ?


Fault with the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

When I press power, light blinks for about 15-20 minutes, then goes off. Press power again, on solid for 30 seconds, then goes off. Press power again, TV finally comes on.


Your television is in need of repair. Hard to tell what exactly needs to be repaired but when the power light blinks in that way then this is the TV's way to tell you it needs to be serviced.

I lost the picture on my 37" LCD model 37MF331D/3. The audio is fine.


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Philips Magnavox 37" LCD Flat Screen 37MF331D Have replaced power board,main board,hit power a faint light on whole screen for about 2 seconds the nothing.


Disconnect the LVDS Cable that runs from the small signal board to the display panel and apply power,if the screen comes on,the Small signal board (aka Scaler Bd ) is the faulty board. other than that,all that's really left that has gone bad for me is the logic board.

Powering on my tv


Dear smmmobil,
The problem lies with the SMPS (switch mode power supply ) of your TV. The smps board needs to be replaced.
