Thanks for using JustAnswer
Please initially check the leads that go into the back of the set and any other equipment you may have like a satellite or cable box make sure the leads are home good and true both ends then......
Is the red missing on other inputs like a dvd or vcr?
If you press the menu button of the sets own remote control can you still see the red missing perhaps in the lettering of the menu?
Let me know please
Thanks for the response. I have tried all of the above. It is defiantly problem inside the TV set. It looks like we lost red color om our TV. The only color we can see is green and blue. I was told that my light engine had gone bad and needs to be replace. This is almost a $1K.
Well if all the above checks have been carried out and you still have this the light engine has failed i'm afraid
The $1 k is a little high however and I would ring around for more quotes
If you think you can do this yourself....
The options are to replace the DMD board DMD chip included $500+ and hell to align
Light engine to be removed from set and despatched to a light engine rebuild company like www.triststatemodule.com $300-$400
Or a replacement light engine $400-$600
You would need to be fairly technical to approach the above work and a service manual is a must have www.nodevice.com should have one
