Maybe part of the difficulty of fixing this problem is how various it is. The APPARENT symptoms are the same or similar, e.g. green tint/contrast problems, but the causes may be different. For example, my US 5005 (Nov'04, hacked 0098) has green tint challenges to boot(AV1,AV2, S-video, other dvds, live TV-- all green in darker scenes), but the recordings are fine, that is, the recorded discs play normally and look normal on my computer and a Magnavox dvd/vcr/tv combo. Additionally, transcoded recordings (from DVD+VR to DVD-Video) look perfect on the Pioneer 563A. Heat's not my problem, although it appears to be the problem for some.
The US 5005 doesn't have a SCART.
I'm going out on a limb here, in fact, I'm just guessing... but I'm thinking that the 5005 thinks it needs a stronger input signal.
Here's why I think that... (I used to sell TVs back in the stone age)
You can achieve a similar-type picture with your TV by turning down the "picture" setting in the menu (This is turned way up at the factory so that you have a bright picture, but it shortens the life of your tube a bit) until it starts going black and white (different brands have different settings "picture" "color" whatever)
Also, with bright scenes my 5005 looks normal, it's only the less bright to darker scenes that turn patchy green
And finally, Green is the majority 'color' in TVs. So when the signal is weaker(or treated as such), it makes sense that what is left is Black and White(not colors) and green.
The simplest way to test this 'guess' would be to connect some sort of signal amplifier between the source (cablebox, DTV box, etc.) and the 5005 and see what happens, but I don't have such an object.
OK... just my two cents.
