We changed the coolant fluids in the blue and green and now the screen is clear in the middle and blurry on sides and color is off on sides also??

You are going to have to Realine the Convergence and set Focus to each Tube on the Screen/Focus block Control.Their is 3 on Top Focus and 3 controls under them for screen drive R/G/B.
You will need to know how to Enter Service Menu:
Do you still have manual that came with TV?

Picture is pale, yet reds are bright. checked color, brightness, and conversion settings. TV seems unresponsive to the color, tint, and brightness adjustments.

Convergence ICs or the resistors powering them are bad. Check for open resistors near the ICs if any are open, change both ICs and the resistors.

Blue screen with sound but nothing else!

I, too, acquired a Phillips without a manual and was experiencing a similar problem. My model is PTV 916, but if your TV has a "source select" button, say a prayer and press the button. From that point, I don't know what else I did, but I do get TV programs now.
