HI ALL
Need advice on our T.V,every now and again the picture goes PINK,

every thing else working,We thought it was all this changing over frequency bit.But just had DVD player on and sceen went pink again.
Is there an expenation for this?or is it dying?and need to get new one
The T.V is about ten years old ,may be more,a NEC brand,never really had any issues with it untill now.And I cant blame the Sydney Mardi Gra,as it started happening before that

,
Anyhow,some one may have some usefull advice
if so Thanks
