Philips LCD 52PFL7403D/27 black screen

[Guest]

I just purchased a used Philips 52PFL7403D/27 LCD. Worked fine for a few days (some flickering, but I adjusted some settings). Now when I turn it on I get the Philips opening screen, then TV goes black. I can hear the sound, no picture. Tried changing the AV slots, still all black. Can't even get the blue menu screen. Please help!

Look for bulged caps in the power supply.
