This indicates a fault in the circuits, its a protection which turns the tv off.

You need to have this checked by a repair man, or get your hands on a service / repair manual.

Magnavox television won't stay on


I know this is going to sound strange but I have something to check. If you have LED lights in your house turn them all off. When they are off turn on your TV and see if your TV stays on. Yes, there could be many problems but this one is cropping up quite a bit. If this does not work then you need to take a look at the power supply board.

Magnavox tv lcd 47" wont turn on it, use to have unplug from the wall wait a wile then it would turn on ,now it wont turn on anymore


I don't have a model number,but am willing to tell you that this is a classic problem. Magnavox LCD TVs have had bad capacitors that will prevent them from starting up and staying on. Thanks for asking and show a few hands of support!

Magnavox 32MD357B - TV won't stay on when first turned on


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of 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. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

My TV keeps shutting off


Tvtek is on the right track. The remote will not solve the problem. Sounds like a voltage regulator in HV circuit if it only lasts a few seconds. If it stays on for a couple of minutes, beam limiter cicuit is pushing to overload and shutting unit down. Magnavox set not hard to repair, but a 27" set is not cost effective to repair either.
