Philips 50PF9631D/37 tv turns on, has sound, but black screen

SOURCE: PHILIPS 50PF9630A/37

Quick test of the plasma screen itself:

1) Turn on the TV
2) Try to bring up an on screen setup menu using the remote or buttons on the tv.
3) Does the menu appear? If so, the screen itself is ok.

If it doesn't come up you make have an issue with the screen itself. I am not sure it would be possible to set contrast and brightness settings such that the picture would completely disappear, but I suspect you should be seeing something on the screen just from having turned it on.

We also need to know more about what you have connected to the television. HD televisions typically have several inputs on them including HDMI, digital cable, VGA and component. Let's say for example you have PS3 connected via HDMI. You can tell the PS3 to send audio across the HDMI cable as well as video. You also have the option of running separate connections for your audio signal. It is the existence of these options that make it necessary to understand where and how you have things connected, very specifically.

You have sound but no picture. Green power light is on and NOT flashing. You get a screen flash or flicker on power-up or even a minute of screen before going all black. It is your inverter board. Common problem on LCDs (maybe more so on Phillips?). They are easy to replace (unplug-plug) and are available on the net.
