| Green is out of focus. I tried to adjust on the focus block but I can't get a thin line using convergence adjustment pattern. The red and blue are fine though and also the convergence. |

| I just found out that there was a coolant leak from green CRT. If the green focus won't adjust, will putting coolant and resealing fix the problem? |

| Yes you can refill the tube. Coolant leaks usually means the set is junk. |

| I took the crt assembly out. I found a rubber expansion diaphragm on the side broken. Can it be replaced? Can I use any Projection TV Coolant? |
