You need to check the primary input ac connection e.g fuse and then measure if you have 330 volts across the filtering capacitor..if this is ok or the fuse blows then disconnect ac-line and check pwer supply eg smps swiching transistor...probably gone to heaven..and replace it and optcoupler..i.e. refere to eventual kit from philips they have repair kits for your tv!...it may be a "standard" problem..if you can get a copy of servicing the smps...in technical manual for your tv it is best...ron

My magnavox tv model num 50mf231d137 will not turn on it turns on then turns off with red light blinking


How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information google.com/+GopakumarGopalan

I have a magnavox model number 32mt3305/17 the green power light on the front panel is on but no sound or picture...just a black screen ...the fuse is good


You have lost your high voltage section, and that is why the TV is in shutdown mode, it has a horizontal output transistor that is shorted, and it is located on a metal heat sink near the fly back. You can have it repair if taken to the shop for about 100.

No sound or picture just blinking green light


That sounds like a power supply Issue, Unless you have the full service INfo and proper equipment its best to call a repair tech for your model as an isolation transformer is needed to saefly diagnose the power supplies.
