Television and Home Theater

I have owned my TV for around 5-6 years now. Shortly after the first year ended the lamp blew and was replaced.
Things have more or less been fine until recent.

Maybe about a week ago someone pointed out to me the color was "off"

I have attempted to go into 'picture' and play with color, tint, vivid etc but nothing has had much an effect. We either go bland/yellow/tan ish or purple and green.

In the movie UP you see lots of red balloons...but you won't on my TV. It is like red disappeared. Women lipsticks all look like some sort of shiny brown..

Went through the blinking light syndrone. Fixed that and tv worked great for about a week.

Now getting code 23. Any ideas or tips greatly appreciated.

46UX16B rear projection television.

When first turned on picture is black and white. Folding and flipping like a '60's tv waiting for the vacum tubes to warm up. Then after about a minute the color pops in but the picture is not clear. Almost like a distorsion but not so bad that you cannot watch.

Would this be a ic convergence chip replacment?

Would it be a power board issue?

Could it be the flyback going bad?

Television does power up. No flashing lights. No codes when accessed.

Any thoughts?
