This different problem power LED blinking and no display. We tray to open screen frame first take out the stand then open the back cover. Second is open all wire (LCD cable, Inverter cables and keyboard cable. Third take out the power board. Now you can see the four capacitors spoiled and around the inverter trans changed color. That means we have the problem of inverter trans need to exchange and two capacitors near to transformer are spoiled because trans gone (this is a solution for no display problem here). And two capacitors near to output cable are spoiled this means 5 V has problem then power led is blinking, we need to exchange capacitor. Better we change all capacitors by 1000uF 25V. Now we will close the back cover and stand. Monitor is okay.
