Got the power going fine, but no luck with the address failure; it's one of the ICs which is bonded to the panel which has failed, hence meaning the only fix is a new panel (not economical.) I haven't spent too much on it so I should be able to sell it for parts, but it sucks that Pioneer would engineer it like this.

As long as you manage to get your money back on it thats the main thing and if you sell the main parts thats even better as its still keeping it from the landfill site.
the address failure do you mean the issues with the picture on the screen?

The address failure causes a 2" wide white bar on the screen. It is caused by the PDP driver ICs on the X of the screen failing on the far right. They are bonded and epoxied straight to the ribbon, essentially making them unreplacable. I don't know why they couldn't go on the X buffer boards.

i get you know pity though i wonder if the person who sold it to you knew it had this problem or could the bad power supply cause this?

I suspect they knew the problem existed but didn't care (may have just put tape on that side, as it is still a perfectly watchable 49" TV with that) but then the PSU went wrong. He seemed honest, it has been in his garage for about a year as the technician he contracted couldn't fix it, or maybe he gave it a go himself, who knows.

Tom strange question and probably very late, but what did you do with this tv in the end ?

Scrapped it, saved the bits, threw the panel out the window and took it to the skip. (Stress reduction!) The plastic screen contained all the bits.
