OK I dont have a manual so a couple of things to check.
First turn the color level all the way down.
If it looks B&W then you have a color problem that will be deep.
If it is red you have a chance.
IMPORTANT if you pull the back take the speakers off 1st.
A newer XBR set had an exploding back, taking it off would cause
it to shatter. Be gentile with it.
Look at the CRT socket board. There are usually 3 controls
R, G, &B. Try turning the R down.
Also look for bad connections especially where there are 3
identical transistors. It can be a shorted CRT. LIGHTLY tapping
the tube neck will sometimes make it flash back to normal.
but so will a bad connection on the board.
Last thing you can try is swapping the 3 identical transistors.
If it turns a different color one of them is bad, you can take
it from there................
Beyond that it gets deep.
Good luck
