The red and green lenses project and the blue is not lighted at all. Are these bulbs available?
This is a CRT(cathode ray tube) not a bulb. A Bulb is totally different. If you replace one Tube, you need to replace all 3 or the colors will never match properly. However, This model no longer has parts available. Even if they were, the cost would be close to $1000 in parts. I would not recommend repairing this TV.

It sounds like your looking for a CRT (red) the part # is on the CRT and could be puchased through any Zenith (LG) distributer- usually around $300- $500. Google the part # when you get it and you may find a used Picture Tube (CRT)for cheaper.

When the TV was last used, the picture was clear and bright as always. It was turned off and when it was turned on a few days later, the blue CRT was not functioning. Is this a power supply issue or a burned out CRT?
