LCD will not turn on power blinks on and off screen flashes same

I have a Magnavox LCD TV - when I try to turn the TV on the power switch light blinks green on and off and the LCD screen will flash like it's trying to turn on - it will do this for hours until I pull the plug - when I wait and plug it in again it's the same the power light will blink on and off - when it blinks on that's when I see the flash like it's trying to turn on.

You have a bad capacitor. Location is 2074, this is a 25 volt 2200MF 105 degree radial cap! Have a tech check any other caps nearby as well! This is a good start for repair......PS no flashing allowed!

Magnavox 37MF23ID, would not turn on. Power button only blinks (green light). We have switched power cords and nothing happens. No picture, no sound.


if the power light comes on but the screen stays black, then your TV might be on the wrong input Channel. for example: you switch inputs when you play games or watch dvds vs. watching regular tv. Try to change the input

My magnavox tv wont turn on just clicks and red light flashes


Sounds like main board fault. 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. http://electronicshelponline.blogspot.com/
