Sounds like a bad component in the power supply. Most likely a bad capacitor.

Power will not stay on , on my magnavox tv model 32mf337b/27 unplugged like user manual suggested but didnt work even after 30 hrs saw on magnavox.com a few people have had same proble with this model mine...


Magnavox has issues with puffed caps on the power supply. This sounds like its a 32 inch lcd tv. I tried searching for a service manual for this and can't find one. If it is an lcd you need to look at the capacitors on the power supply. If they are puffed up, you will need to replace them with equal or slightly larger valued capacitors. The capacitor values are mfd and voltage printed on the capacitors themselves. You will need a soldering iron to replace them. Lay the tv, if it is an lcd, on a flat surface cushioned by a blanket. Make sure the surface is large enough to support the tv frame, as you don't want to cause damage to the panel. remove the back of the tv. There are numerous screws, and once the back is off, check the power supply pcb for puffed caps. This is the board with the power cord attached. I know in magnavox tv there is a cage covering the power supply, so remove any connectors because you will have to flip the cage housing the power supply to get to the caps. If you feel confident, give it a try. Let me know how it goes
