LG Monitor L19NT-A with interference on screen help

[ivtec]

Hi guys; I already posted in the computer forum but did not get any tips on this Monitor issue, may this is the right place to post this issue!
I send new Pic how this intermittent fault goes away by pressing 2 fingers against each other in the middle top edge of the panel.
Any help would be appreciated

Nice vid. Your Mr.Buzzer is a interference suppression film capacitor 450nf, 275V. I'd check that first with a capacitance meter. It should read 450nF. With an Ohm meter it should be 1Meg and charging up a cap. You can find these caps on other power supply boards from other LCD monitors and TV's. Swap it, check your display again for noise in the signal.

Thanks CapLeaker; why when i press on the top edge of the panel it goes away every time? see pic with attachment that i posted a couple threads above.

could try putting something there where you put the pressure, for better contact, then reassemble, seems like loose contact in that section.
