That depends on the value of the television and the cost of replacing the power supply and connections.
Most likely you have a short in your power supply or other connections causing the tv to protect itself by shutting down. You can check with our Repair Service lookup icon for a repair service near you.
Before you call them you may try unplugging your unit for 30 minutes or so and plugging it back in.

My magnavox tv will not power on light turns yellow


I have many thoughts to this problem, having seen many sets before in the past, one issue could be software related which all sets now have, with value range sets this tends to be a more basic code and can be easily bothered by other remote controls for other equipment and lock up, so powering off and trying again is a good starting point.
Remote controls can suffer with poor battery connections or batteries which in turn cause a remote to miss-fire a command, in another answer on fixya I pointed out that its rubbery buttons or contact mat under plastic buttons can sweat leaving a residue which causes miss-fire (the amount over the years I have cleaned).
Its a matter of prying apart (and or screws) if you are lucky clean contacts with meths spirit and soft rag (few are glued together but most are clipped).
In a modern set they have many little power supply circuits for each system (oldies had one big lump) these have to fire up within a certain time or a "fault" is deemed by the system so goes to standby or shuts off, if the set repeats this problem in a short time period it may have a fault which only an engineer could solve.

Hope this helps

My magnavox tv model num 50mf231d137 will not turn on it turns on then turns off with red light blinking


How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information google.com/+GopakumarGopalan

When i go to turn the tv on the green light go on and then off. i did the coe test error code repeated 10 times


I found that by simultaneously holding down the remote control "power" button and "volume" button for about 30 seconds the blinking light would go out and a solid green light would come on. Even though the solid green light came on the unit would still not power up. After doing this several times however the unit did finally power up in a normal mode and appears to be working again

Flashing green light


Did you try this yet

SYSTEM RESET
If the TV will not respond to either the remote control
or the front panel controls and/or will not power Off,
press the SYSTEM RESET button with a pointed item
like the end point of a paperclip. The TV will turn Off
and the TIMER light will flash quickly for about one
minute. When the TIMER light stops flashing, you may
turn on the TV again. Changes you made the last time
the TV was On before you used the SYSTEM RESET
button may be lost, however, the changes you made
previously are not lost.
POWER/TIMER Indicator
The green light is a multi-function indicator. This light
will flash rapidly for about one minute each time the TV
is plugged into the wall electrical outlet, when power
is restored after a power failure, or using the SYSTEM
RESET button. Do not attempt to turn on the TV again
during this period. Wait for the flashing to stop and
the light to turn off, before attempting to turn the TV
on. While the TV is powered on, the light illuminates
steadily. If the TV has been programmed to turn on
automatically using the Timer feature,

Watching tv when the picture went black and now the green on light flashes for 30 times and turns off


A green flashing light for this model of TV indicates that the lamp cover is open on the TV.
  1. Unplug the power cable to the TV.
  2. Remove the 2 retaining screws on the lamp cover with a Phillips type screwdriver.
  3. Remove the lamp door completely from the TV.
  4. Remove the two retaining screws on the lamp case.
  5. Lift up the fixed wire handle of the lamp.
  6. Pull out the handle slowly and remove the lamp case.
  7. Insert the new lamp gently into the correct position. Make sure it is inserted correctly.
  8. Using a manual Phillips screwdriver (Do Not use an electric screwdiver), tighten the screws you removed in
    step 3.
  9. Replace the lamp cover and tighten the cover screws.
  10. Plug in the power cord and turn on the TV. After the initial warmup period (which may take up to several
    seconds for full picture brightness), the TV should operate normally.
If any of the following conditions exist, turn off the TV, unplug the power cord, and repeat steps 1–9 to ensure that the lamp unit and lamp unit
door are installed correctly:
  • The lamp indicator flashes green.
  • No picture
  • Dark picture
  • TV will not turn on
If, after repeating steps 1–10, the problem still exists, call Customer Service at 1-800-631-3811.
