Brightness weirdness on Philips 20PT1553-00

I recently obtained an Philips 20PT1553-00 TV set. The picture is usually relatively dark. I have to turn the brightness and the contrast fully up to obtain a viewable picture. The effect of the brightness-control is nearly non-existent. Sometimes (very seldom) the whole picture brightens up and the brightness-control works. This lasts usually bwetween 5 and 30 seconds. After that, the picture turns dark again.



Has anybody experienced something like this before? Does anybody know what could be wrong?



Thanks

The turning-dark-again always happens, when I try to adjust the brightness of the picture after it turned bright. As soon as the brightness is at approx. 2/3 the picture turns dark. The effect is not temperature dependent (happens after 2 hours or direct after switching on the set).
