Maganavox flat screen tv no pic, red light blink codes...

Maganavox flat screen tv build date Aug. 06 for Dolby Laboratories, model number 50MF231D/37, 480 watts, turns on after power has been unpluged but at ~ 10 seconds goes from green light (on) to red light blink code. No picture, no sound, no menu options at this point. Red light blink code is 4 rapid blinks in about 4 seconds, pause 3 seconds repeat. TV is hooked to sound system so no direct sound to tv only red, blue, green wires. Signal comes in through direct tv with DVR box. Took down last night tried with other system using red, white, yellow connectors. After moving and after worked. Put back up and worked. Turned off for the night, then same problem again this morning....red light blink codes, never got picture again.

The LED blinking 7 times is a code to tell the service tech what is wrong with the TV. From what I've read at other sites it sounds like there;s a good posibility that it is a power supply gone bad.

You probably should call a TV repair shop for assisitance.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
