What makes you think Blue tube is Bad ,It may just need coolant fuild changed out.

HI, thank you for visit fixya.
Common problem on this set .
Picture tube liquid is dirty.
Mostly in crt green and crt blue.
Do you have electronics skills?. If so, open the TV ( back cover), you will see green,blue and red gun. After turn on your tv, select any channel or video signal, cover with piece a paper two guns at the top ( any), and see how look the picture in the front, try one at time, ( press menu on remote control and see leters-clear). I am sure the green and blue will be no clear. all the time red tube is fine.
REPLACE COOLANT LIQUID PROJECTION ( solution).
I will be here for any quetions.
Thank you

You CRT coolant needs to be replaced, its a very common problem with the phillips and magnavox projection TVs. If you need more info on the Coolant Change let me know.

It is not the gun ,but the convergence IC that needs replaced providing that you have went into the tv menu and selected convergence and manually adjusted the blue convergence.

Sincerely the Hammerman

If the red gun stops working it could make the picture very blue-greenish. This could be caused by a number of problems, including a coolant leak, but it's most likely a bad electrical connection somewhere in the set.

Best left to a professional repair guy, frankly.

If you are still needing the red gun for the phillips I have a link that I will post that has one complete with yoke, Purity rings, lens and coolant chamber. Here is the link they offer free shipping also.

i suggest to have it check by a qualified service technician. there seems to be a problem with your crt (cathode ray tube). because inside this projection tv are 3 crt guns responsible for color red, green and blue, which only qualified technician can adjust it and replace if it is necessary.
