If it is a new TV and under warranty, return it. There is an internal fault and it needs to be serviced.

have your unit power supply check, maybe some cold solder or leaky capacitor is the culprit.

SOURCE: magnavox 15inch lcd shuts itself off

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Upside down


Your Horizontal and Vertical Flip is reversed for some reason. This will be a little difficult to do/see, but turn on the TV and Press the Menu Key. Goto "Lock" and press OK. Once you see the Lock Code Box come up, press and hold the Volume down on the TV and the OK Button on the Remote for 5 seconds or more until the TV shuts off. This resets the Memory.
If that doesn't work unplug the power from the TV now for 60 seconds then plug it back in. It should power up at that point.
If that doesn't work it is probably an issue with the Logic Board and a Re-flash of the Logic Board from a Company who has the Equipment to do so will fix it. This shouldn't cost anymore that $150. Goodluck!

Picture keeps going out on Philips TV 47PFL3704D/F7, 2009 model. The sound stays on. It happens very randomly-may be fine for several hours, may happen every few minutes. Also happens when playing video...


I think that the connectors from the backlight inverter board that go to the LCD panel's backlight are a bit loose which explains why it comes back on when tapped. I am positive that unplugging and replugging the inverter cables should do the trick. WOuld like to do it yourself? It requires you to open up the tv ofcourse.

My Magnavox digital converter box shuts itself off every 5 minute


Check that you have not got an auto power off setting on. Check that the aerial connections are good. That the signal is strong from the stations it is picking up. Weak signals can cause the box to shut down.
It the box is very hot when it shuts down, you might have a fault on it.

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.
