Sony rear-projection TV with color problem

[[email protected]]

Hello people,

I have a Sony KP-46S15 tv with some strange problem. The picture is
good, but it's black/white, doesn't matter if it's cable or video
input. But, the weird thing is that the OSD is colored, all the menu
items are normally colored.

This color problem was flickering some time ago, and now it's
permanently B/W...

Any tips?

Basic troubleshooting would be the tip. If you need tips at this point, you
need a tch to evaluate the set.
