Question about Televison & Video
Replaced convergence ic,s no improvement. Manual red convergence works, but blue still does not. Noticed that red and green CRT,s reflect their colors when a light is shined at them, but blue does not, no blue reflective color. Could the blue CRT be bad and not manual converge?
How about looking into the tube when its on. if its cloudy then change the fluid in the tubes that need it. usually the blue on these seem to be the first to need it. I have never replaced the crt on these.

Thats a very strong possibilty the phosphorus may be burned off the CRT face. Does the blue project when powerd up and looking in from the raer of the set? Look into the blue CRT lens while its playing If you can see a clear picture I would think that you have some open resistors in the blue circuit, If you cant see a picture its time for a CRT. If you need a CRT let me Know I have a good source for them Used.
