Question about Computers & Internet
You most likely have bad caps on the power supply board.
Most visibly bad will be the 470uf 25v caps. The tops of the caps will be domed or split and leaking.
Then two of the larger caps. 680uf 25v, and one small cap. A 22uf 25v. All of these need to be rated at 105c. You can use higher voltage caps if you have no choice but not lower.

I have the same problem with a customer's monitor (LT716S); it turned out to be damaged power supply board. As I understand it, MAG has a 3 year warranty on parts, will probably charge you a flat labor fee plus shipping. If you do not have your purchase documentation for warranty, dump it and replace. If you can, then you may wish to have it repaired.
My customer replaced theirs; I am trying to purchase replacement parts to repair...good luck.
