Curious TV fault: advice appreciated

I have a small unbranded LCD HD TV which I use for occasional casual viewing when I don't want to fire up my projector. It's fed from the HDMI output of my AV amp, through an active splitter which also feeds the pj.

Today I tried watching a signal routed directly from a DVD player into the set's composite video/audio inputs. I've done this before and the quality has been fine - nowhere near HDMI standard obviously, but perfectly watchable. But today the picture was appalling: hugely over-bright and washed out. I tried changing the set's picture controls but couldn't get anything like a decent result. A bit of experimenting showed that the SCART input gave the same fault and so did the TV's own built-in Freeview tuner (which in the past has also been fine).

Is there a known type of problem which can cause every input except the HDMI one to give such dreadful results? Any thoughts will be very welcome.

If I were you, I'd try resetting the TV.

Thanks, Rob. I'll give it a go in the morning.

Edited to add:

Well, that did the trick, so thanks again for the suggestion. What a strange fault, though. Mind you, the set does have another oddity: the aspect ratio can't be adjusted on an HDMI signal. It seems that that input does indeed bypass some of the display circuitry.

The HDMI interface was designed solely as a widescreen interface so any provision for aspect matters, if any is provided, has to be done in the source box.

Gavtech, that's interesting; I can (fortunately) adjust the aspect ratio on HDMI signals on my projector, but, from what you say, that must be quite unusual.
