monitor turns off and on repeatedly

[Gfurr2]

had this problem for a while except it does it for a couple minutes and then it turns on 

but now it just does it forever it just repeatedly turns off and on

Faulty electrolytic capacitors (swollen, leaking electrolyte,degraded) cause the power supply to be unstable and "crash" when the backlight controller tries to turn on the backlight (too much sudden power draw) and causes the power supply to reset.

 

You'd have to open it and replace capacitors with suitable ones, if you have access to a soldering iron/station replacement capacitors would be 2-3$.
