Magnavox rk4490 ak05 tv will not turn on

Each time our power goes out our Magnavox rk4490 ak05 tv refuses to come on for hours or days. There is no "click" when you hit the power button on the tv itself or the one on the remote. We can hear the sound when we turn our satellite and surround sound on but cannot get the tv to turn on!

capacitor problems in power supply or a regulater isolate the power suppley by disconecting the line output stage/unplug scan coils for example and run a 60w bulb as a dummy load one wire to earth and the other to rail voltage colecter of line output transister if the bulb glows steady the power supplys fine

SOURCE: magnavox with pic tube tv skips over channel 3..goes from 2 to 4

You are right about the auto-programming, but Magnavox no longer has the original remote.

For my answer to be right, you must have posted this question to the EXACT CORRECT model # of your Magnavox TV - 27ms343s:

Press TV on your Verizon remote, and then press "0" and "3"

If that fails:
Press MENU to see the TV’s on-screen
menu. In the menu, use VOL.+/_ and
CH.+/_ to make adjustments or selections.
You can press MENU on either the
remote control or the front of the TV to
access or remove the menu.

My magnavox 42mf438b lcd tv will be fine for about 10 minutes when i turn it on, then the screen goes completely black but it still has sound. it stays like this even if i turn it off and back on. i can...


that set is highly rated by users .. it first came out in early 2009 (i think) so you might check to see if any warranty remains ... the display is illuminated by several lamps .. each lamp has its own high voltage inverter .. all the innverters are powered by an output of the low voltage power supply (often 18 volts)... i would suspect a problem with that low voltage power supply.. either a bad capacitor or a thermal issue .. .. ..

Magnavox 42 LCD 42mf438b/f7 turns on/off by itself sometimes screen goes blank tv unresponsive to remote


I have exactly the same problem with a Magnavox LCD 42", very similar model 42MF437B/37. I don't have a solution. If you unplug the TV and plug it back it starts working, sometimes for hours, sometimes for less than 5 minutes, before it turns off again. Does anyone have any real solution?

Magnavox lcd tv not turning on


Also changed swollen C2074 and C2081 and it now works perfectly! a bit daunting for a novice like myself but with a steady hand and decent 'put it back the way you took it apart' skills, all went well!

Picture goes off


A temporary solution is to unplug the TV for a few minutes, remove static from the glass with your hand. It is important to unplug rather than turn off. If you have a degauss button you can also press that before unplugging. Wait several minutes or an hour. Then plug it back in. If you have Picture in Picture it may be an issue with that and to permanently solve may need a repair person. The unplugging may get you by for a few days at a time. That's at least better than an hour.

TV turns on at odd hours by itself


Hi, I had the "Ghost In The Machine". I tried out what I descibed in my original posting.
#1. I unplugged The Set.
#2. I pushed in and held in the power button in for about 5 minutes before bedtime. ( The PC trick I learned) I gave it 5 minutes because a tv set has much more power inside it.
#3. I again pushed in and held the power button in again for 3 minutes the next morning.
#4. I plugged the tv in again. The red standby light was lit. The set did not immeadiatly come on when I tried to power it up.
#5. 5 Minutes later I returned and hit the power button on the remote and it came on like nothing ever was wrong.
#6. It has been fine now for 3 days!!! Powers up when commanded and shuts down like normal. It has yet to come back on or act up as it was doing.
I will keep a watch on it and if it starts up acting again I will repost. I hope this information will be of use to anyone who experienced the same problem. It didn't cost a dime, just some patience. Thanks for a forum that people can exchange information and save trouble and money unless all options are exhausted. Bill
