right ive got a techwood lcd tv with hdmi compatibility,and got my xbox360 running through it on a hdmi cable,all was well,until a few hours ago and now,no matter wether i use scart or hdmi cable the screen looks like its an old ega/cga picture,all blues and cyans,the picture is still there but in the worst quality EVER!!!!please tell me i can do something about it?
cheers

 

same display regardless of connection? what about with a dvd player or some other signal source?

 

ill try that,but yeah,hdmi cable,scart and the scart like hd cable (5 pins) all do the same

 

oh dear,just tried another tv and its fine
so ive screwed my dads tv then?shit!

 

Try turning it off from the wall for 30 seconds..

 

Only blues or cyans means that the red signal's not reaching the display driver. Use a different input or a different cable and see if it changes things.

If the display's the same regardless of input (tuner, SCART, composite, VGA or HDMI) then yes, it's most likely fucked.

It might be something simple like a loose ZIF connector on the input board of the TV, but you'd have to open it up to find out
