Magnavox MWC20T6 Powers self off after 10 seconds

I have a Magnavox MWC20T6 TV. When i power it on, it turns off by itself after 10 seconds. It doesn't matter what settings it is on, or whether is it on TV, DVD, or VHS. I am a professional computer and network repair technician, so i'm not afraid to do the work myself. Does anyone know what the problem is and how i would go about fixing it?

Thanks

SOURCE: Magnavox TV combo with Dvd & VHS will not stay on.

Frist of all the tv is made by Funai the next thing is it is very hard to get parts from Funai at least it has been for me they tell me anywhere from 2 months to a year on parts. Now if the set is trying to load a tape without a tape being put in then shuting off you have a bad diode on the main board.Part is marked (D1224 on main board which it is called (LED) the Funai part number is (QPQS1R563ST) Need to replace this LED per Funai tec i have done this on a few of these models this problem stands true for 20 inch 24 inch and probley any others that are made by Funai that would have this kind of problem. The led that im talking about is under the VCR chasie in the center of the board and is clear glass looking. It has to be put inone way for it to work you have to unsolder it from the board. If you are not able to do this then it would need to go to a repair shop to be done. The shop may or may not know what is wrong so you could tell them, let them know that this is per Funai tec fix for this problem also give them the part number and hope that it does not upset them some shops would be ok with it and others would not.

This is most likely the reset control on the back of the TV. When power is turned on it goes through the reset button and then to the TV. As it weakens over time, it can create the problem you have. See if the web site manufacture will sell you that part, or take it to a TV tech. for replacement, about $10 for the part not including the labor to take the back off and replace the part.

How to resize picture on a magnavox mwc20t6


Look for a setting called Aspect Ratio. It will include options like 4:3, 16:9, Zoom 1, and Zoom 2. Then click through the options to select the correct one for your program. Usually older SD programs will use either 4:3 or Zoom 1, while HD programs will be set to 16x9 for Widescreen hi-def viewing. There should be a button on your remote labelled Aspect Ratio or Picture that can toggle through these image modes.

Magnavox mwc20t6 doesn't turn on


Hi
If you have a friend that is keen on electronics, your tv set may be open and checked for a blown fuse, as a firt step of troubleshooting. This is applicable when no light in the front panel is on or blinking. If this do not work or the fuse blows again, there is a short circuit or a bad component that need to be replaced. But this task require another approach.
Please follow the instructions on dealing with high voltage parts of the tv set.
I shall be glad if this is helpful.

Magnavox Model # MWC20T6


Manual will not help - if you unplugged it all night, and it will still not power up, try one more outlet in the house. If it still will not help, then you need to replace the power supply for the TV. Sorry.
