Convergence problem? Service manual needed? KP-48V75	Can't Post

Hi,
Looking for a little help with my Sony kp-48v75. While trying to get the convergence correct, I noticed that the blue is very blury, it looks like it has a halo around the blue cross. I try to adjust the convergence board, no luck on tring to clear it up.
I'm pretty sure I need to go into the service mode to make some adjustments, just tring to figure out which one.
Anyone with any ideas? Service manual?
Thanks for your time.
Jim

Not a electrical adjustment, sound like the coolant is contaminated, I would check this out before you mess with the service menus

Thanks for the reply, how can you tell if the coolant is contaminated? Will it be discolored? Cloudy?

Thanks again
Jim

Thanks again for the reply
Just checked the coolant, I had to go though the back of the TV, I did not want to remove the screen just yet.
Anyway, the coolant in the blue tube, looks a little cloudy, hard for me to say as I never looked at it before I had this issue. I guess I should change it. Any good web site showing how to do this? And good places to buy the coolant?
Thanks again
Jim
