The Way Im understanding your problem is,
it seems like you need to hook your rcas directly to the tv and switch the surround to aux or something similar to that.

Bad power supply or backlight inverter.

If the backlight is not turning on, you should be able to see the lcd image by shining a bright flashlight at the screen.

Backlight inverters are loud, so you can hear them operating (high pitched whine) and if the backlight is coming on, you can see white light leaking around the edge of the screen, and even a little inside the cabinet.

Philips are legendary for having power supplies that fail due to bad capacitors, so that could be the culprit as well.

If you really need to buy a PC board, I would contact Philips to see if they are still made. They should be able to tell you who can supply one if they do.

You probably have a component breaking down on one of the circuit boards. It would have to be checked out to find out which one. Stargazer
