My old NEC 68cm Flatscreen TV has started getting the "blue screen" intermittentaly (and it's no longer all blue but has violet fringing on the upper and lower left hand corners that extend about 1/4 way to middle.

When the picture was getting lost momentarily , initially I thought the problem was withthe signal but I have also noticed the colours are off when the picture is "fine" .

Short term - I have selected 9/16 aspect from the set top box and the DVDR VCR combo and that reduces the effect , but I know it's there so I can still see it.

Am correct in assuming the tube is on it's way out ??? ... got a vague recallection that this is what I saw on the old Sanyo 54cm before the picture tube died all together.

Worth getting a TV service guy fix it ?
or should I just wait for the tube to pack in it because it's likely to be a pricey job fixing the problem ?

I don't want to replace the TV just yet (unless I have no choice), am waiting on HD 1080 plasmas and LCDs to become less power hungry, their technology to become more reliable and , of cause for the price to fall a bit more.
