The back light inveterate board and CCFL lamps should be checked. Check and replace the faulty component. Back light inverter can only be replaced as card basis.

it was an inverter board and screen back light issue. you must check loose connector like dry joint .

Tv turn on now,pictures only flashes few sec. than dies have audio left only?Yes,than the tv 2 long LCD inverter boards are dead.These 2 long LCD inverter boards help the LCD screen panel to have a backlight to produced a picture.Tries websites like Shopjimmy.com,Ebay.com to buy those 2 long LCD inverter boards for the replacement.

Hello, I have exactly the same problem with the exact same TV, white screen for about 15 minutes and than image appears perfect as if nothing happened. I have asked an ebayer which sells TV parts and he suggested it could be a main board or tcon board. I am quiet hesitant to fix my tv, but if the tcon board would fix it, i'd go for it. Did You manage to solve the problem yet?

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.

The antenna jack may be loose, but that's not your issue. The screen image shrinking is an indicator that the tube is going bad. If this is a plasma or LCD then you have a circuit board issue. Time for a new tv, I'm afraid.
