37" Philips LCD sound but no picture

If the backlight of the LCD-panel does not function, (no picture) then Master and/or Slave inverter are defective. Inverter boards are screwed to both sides of the LCD display, if they have revision 1.2 boards then they will need replaced with revision 1.3 boards.

I am suffering from the same problem. When I turn on I get sound but no picture, although I do get the backlight coming on when I turn it on, I then get about 1/2 a second of picture then nothing. Even if I select TV specific functions such as the menu, I get no menu screen come up.
Any ideas out there?

Your tv is being attacked by electrical surges which seem very violent and has already damaged some logic controls. Please invest in a AC filter which will protect your tv from such spikes....... but first you need to get your tv serviced from the electrical damaged it has already suffered.

control boards on LCDs and PLASMA tvs are causing no picture , missing area , and other wierd symptoms , it will need to be tested to determine the true problem

Philips 37PF7320A 37 no power but the green light is on

When I turn on my TV it goes straight to the menu screen. You can still hear sound but no picture. When I try to exit you see the picture for about a second then it automatically flashes back to the menu screen. Even if I try to use the functions in the menu screen it flashes right back to the main menu screen. Very frustrated...need help!

Rest the tv by unplugging it from the wall for a hour. If the picture is still gone replace the small signal board.

The problem is the small signal board that is the video processor.
