I will make this as short and factual as possible.

Blue and green guns work fine

red crt does receive voltage through "screen" and "focus" I.E. I can brighten the crt with the screen setting and focus the scanlines with focus.

As stated I can see scanlines when looking into the lens.

There are no menu displays showing on red crt. G/B crt works fine

This problem is across VIDEO and Input A & B

I am hoping some one will tell me " replace cap #163 or something but I am expecting replacement of a board.

Thank you

Most likely the CA(G) board. I may have one left. PM me, $75 incl shipping within North America, $100 outside of North America.
