monitor turns on and off every few seconds

Kaye Andrea Ruiz  tell us what happens when it turns off. Let us know if the Power LED goes out or if it is just the screen that goes dark. Shine a flashlight beam at an angle against the screen when it is dark and see if you can still make out what it should display. this is most likely a main board issue but could be the power board as well as the backlights. Hence we need more information. Another thing you can try and do is to remove the back from your monitor and take some good pictures of the boards. Post those pictures with your QUESTION so we can see what you see. Voeg afbeeldingen toe aan een bestaande vraag
