60 inch maganavox rear projection tv blue color almost gone if it is a bulb where can I buy one

Tv have CRT coolant chemicals problems.Tries websites like Tvrepairworld.com,Tvrepairkits.com to buy a CRT coolant chemical kit to used.

Your problem sounds like the projection bulb is going bad. It is the main problem with projection TV's, and is usually very spendy. I would recommend calling Zenith and request a new bulb.

that means that the phone needs to be unlock by the network provider

This is a common problem. Its called a convergence failure.

Problem #1) Convergence

That requires the fluid being replaced in the Blue tube. I suggest that you have a qualified technician service it.

Replace the STK730-130 IC. You can get the IC at www.tvrepairworld.com under the convergence IC Catagory

IT NEEDS A LIGHT ENGINE. COST A LOT TO REPAIR.

the picture tubes are liquid cooled,coolant is contaminated and mist be changed.any questions just give us a call 410-388-9399

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images. 

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.
