Sony KV-32LS60B - CRT - Colours a bit off

[tmcw]

Picked up one of these recently, has an AE-6B chassis. Works fine, although the colours seem to be a bit off, don't seem to be as vibrant as I would have expected, so I'm wondering if anyone has had any experience with these sets, and is there anything I can do to improve the colours?

When I adjust the colour, I can get it on the scale to go from B&W to completely exaggerated colours, but somewhere in the middle where you would expect it to be ok, they just don't look right, so maybe it's an issue also involving the contrast and brightness. It's hard to explain, not sure if photos would help. I mean, greens look green, and reds look red, but it's hard to get an overall satisfactory picture through the adjustments. Whilst some of the background colours may be ok at one setting, skin tones look a bit pale, for example.

In the service menu, I can see that there are nearly 27,000 hours on the set, so possibly the tube is the problem here?

I can post pictures if anyone thinks they would help. I have another 21" CRT or a 26" LCD that I can post comparison pictures of the same feed, or what is the best way to take them?
