We solved the problem with Sony experts from Vio. Thank you

Unfortunately, there are a couple potential problems. First of all, if you RCA rear projection tv is fairly old and is not a High Definition tv, you may not have an hdmi, dvi, or component connector cables inputs. Without these, you are left connecting your blu-ray only by the standard yellow (video), along with the audio (red and white) rca cables... either way, the High Definition portion of the blu-ray won't work with a non-High Definition tv. It may be time to buy an HD capable tv to use your blu-ray effectively...

The tv will show correctly in 720p mode. Cable box and PS3 must be set to display in 720p or the green tint will remain. For the PS3 I return it to 1080p when I am about to play a game, blu-rays and dvd's can only play in 720p.

It is my understanding that the 46F500 HD Ready only goes to 1080i and for Blu Ray you need 1080p. There are no ports for this format.

Sounds like convergence issue....Can you describe " colors
go nuts"..........If red green or blue separate, replace STK392 IC's
located on large heat sinks.........T.
