H.D. C.R.T. anyone?

[MX70]

I have a Toshiba 30HF85C (2005 build) CRT widescreen that I picked up for free (all 111 pounds), even had the remote and manual . The previous owner was just glad to get it out of his garage. Not a bad set, it works almost perfect but the edges of the picture show some colour separation, perhaps covergence needs to be performed? Also the HDMI, while working perfect with my Telus Optik box, refuses to work with my Playstation 3. The set will do up to 1080i, and I have seen this issue with another Toshiba HDTV model similar to mine where it didn't cooperate with a gaming system using HDMI. I just use the analogue component ColourStream inputs with the PS 3 as the games I play are only 720p anyway. I did miss out on a free Sony KV 34XBR920 at about the same time I got this set but then I would have needed to make space for that, and probably would have put my back out too
