Sony KV-34HS420 - Color Problem on HD Inputs

I have one of these TV's that has a problem with the color on both the component and HDMI inputs. In short, there is no green in the image. It's like when you're watching something over component and unplug the (Blue) Yb cable. However, all connections are secure.

I don't believe it's a problem with the TV's green gun going out because I have green in my image in both the system menu, and all standard def sources such as composite and S-Video. If I can't get proper color with the HD inputs on this set it's worthless to me. Can anybody help me shed some light on this problem? Thank You!

What is your HD source? Have you tried a different source? How long has it had the problem? Did it first occur coincident with any other changes?

If component and HMDI signals both run through the same control board on that set (you'll need a Sony service manual to know) then that's likely the problem area.

Thanks for the replies guys. My HD source is a Toshiba HD-A2 player playing Digital Video Essentials on HD DVD. I've also tried several HD movies on HD DVD as well as Comcast HD programs. It's had this problem since I bought it a few months back. My biggest mistake was buying on craigslist and not properly evaluating the TV before bringing it home. Although the guy I bought it from was running a PS3 through it and it I didn't notice any problems at the time.

When u enter the service menu you will see an adjustment named RCUT short for red cut or red low light. This adjusts color for the black portion of the video signal. Lower this setting and the black should return to normal. Be sure to adjust only that setting (or BCUT and GCUT (if theres a GCUT)).
Once your black is black press Mute and then press Enter on every adjustment you made. If u made an error, close the tv and start it back and do not save. good luck! Neccrttv

And be careful because resetting to factory does not affect service menu...

^ I assume neccrttv means "resetting" in the User Menu above. Resetting the Service menu will have definite detrimental effects on the TV. So you should never even consider doing that.

Yeah I meant the user menu (which is most likely what he tried since it didnt change anything)... cause if you reset service menu to factory... you're in for a whole new level of pain lol...
