The power light (green) flashes on and off for an extend period of time then it turns off. This is repeated several times until the television finally turns on. I am tyring to figure out if I should fix it or replace it.

Re: Magnavox # 37MF231D
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.

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.
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
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
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,
get a memory stick( flash drive) and up load their soft ware from their
site. I plug the stick into the computor and uploaded the software.
I then plugged the stick into my TV on the side. A screen came up and
the software loaded on the TV successfully. The red light then turned
to green. However, I now have to unplug and plug the TV several times
for it to turn on. It works fine but once the TV is turns on, but when
I turn it off and it cools for a while I have to repeat the same
proceedure off plugging and unplugging
Dont know if its the same model but Ive seen a few with a cold solder joint on a switching relay in the Vertical circuit do this.. (Be careful if its a CRT TV.. 27.5KV is common off the flyback transformer).. 27,500 Volts.. Good luck!
