My hitachi rear projection tv has a very green picture. This issue started out as a red blob, which is still present, but now the total picture has a green tint to it. Is there any easy fix to this issue or am i better off buying new technology.

unplug your TV look on the back for a three controls marked red / blue / green "screen" turn / tap on them; watch the screen when you find the "dirty" control clean it with "TV tuner cleaner spray"
I have the same tv and the same problem, but my yellow is a cloud around the outside of the screen. My tv was recently moved, and a repair shop told me that sometimes in a move these tvs light engine takes a shock and causes a yellow "band" on the screen. I am hearing that these light engines are not cheap either. Hope this helps you.
If its a LCD projection TV (such as Sony Wega, Hitachi, Epson, Philips,
and some Panasonic, some Mitsubishi), and the green image is in the whole
screen or just one part as a blob or a line. Is most probably that one of your
LCD Color Filters is damaged (burned out or starting to get busted), I don’t
know if you can just replace the color filter, I believe you need to
change the whole light engine system or the optical block. There are some
places around, I found some on ebay but you should definitely try on
discountdashmerchantdotcom their price range $260.00 - $330.00
Suggest you call Hitachi and complain. There is an issue with all projection LCD tvs (not just Hitachi) was that the light engine assembly did not have enough vents for cooling. This translates in a green or yellow blob that starts small and grows larger because the LCD screen frame starts to deform with the heat. Guess they did not test with young kids in the house and the tv on more than it is off :-). In March I managed to get Hitachi to pay for the part and I paid for the labor to get this fixed (out of warranty). The new light engine supposedly is better at cooling though I do see a faint 1/4 inch band of green at the bottom of the screen. Blackburn Electronics in Anderson IN has fixed many of these in the Indianapolis area.
your set has indications of several problems. red green and blue. indcate convegence issue. the fact that the picture is concave is a indication of totall loss of covergence power supply. the convegence menu missing idicate loss of some voltages from what know as the flyback.AND SHUTDOWN. indicate further problems. generally when convergence fails ..not always the set wont shut down. it could be a simple issue but further trobleshooting would have to occur to narrow it down.
toni, you`ll need a tv tech for this problem, spark gaps need to be cleaned, crt sockets need to be cleaned and crt pins on all 3 crt`s need to be sanded, this is a common issue with this model set, good luck, BMW Rider
