SOURCE: Need info on component 3071 on power supply board - burned up.

Its been a while since i worked on that power board. But I believe you are refering to the orange diode that runs into the single connector for the video board next to the power supply. I replaced mine with a 1n914 diode after replacing the 2200uf lytic cap and the tv fired right up.

First place to look will be the power supply module, look for bad caps, check the output DC voltages, it will be an in-depth troubleshooting to narrow down the problem.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

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:

SOURCE: I NEED A POWER SUPPLY AND CORD FOR A MAGNAVOX 15'

Either you can get this universal type available inthe market in any electronic spares store or it is easy too make one by yourself if you are familiar with electroncis.
All you need is a mains transformer with secondary voltage at 12 volt and 4 amps capacity, use a bridge rectifier , good storage capacitor of about 4700mfd/25 volts and if possible use a 12 V regulator so that the power is smooth, regulated and protected..

It sounds that there is some shorted component/s one either main power regulator board, or at the main digital board. Your TV need a through checkup.

Magnavox 42 LCD 42mf438b/f7 turns on/off by itself sometimes screen goes blank tv unresponsive to remote


I have exactly the same problem with a Magnavox LCD 42", very similar model 42MF437B/37. I don't have a solution. If you unplug the TV and plug it back it starts working, sometimes for hours, sometimes for less than 5 minutes, before it turns off again. Does anyone have any real solution?
